Résumé :

Using local newspapers and tracing the origins of several stories about the development of the sobriquet “Yellow Dog,” this essay demonstrates how the heritage trail markers erected in Moorhead, Mississippi, silence the origins of the term in the suffering of African American men and women who worked in the rolling convict lease camp that built the “Yellow Dog” railroad through the Great Swamp. The marker’s text instead forwards a dubious debate over the term’s origins, excluding its true beginnings in the experiences of African Americans. The heritage trail markers at Moorhead are only one of the examples of how professional state consultants and the Delta Center for Culture and Learning promote racial division—not reconciliation—through erasure of the African American past.

Résumé :

Clinical History: A 2-year-old, female Poodle dog presented to the Emergency Service at the Veterinary Teaching Hospital (VTH), Louisiana State University School of Veterinary Medicine with a history of lethargy and anorexia. At clinical examination the dog was anemic and febrile. The dog was bilaterally blind. The right eye was buphthalmic and the intraocular pressure was elevated (42 mm Hg). During an ophthalmological consult, bilateral severe panuveitis and optic neuritis with secondary glaucoma in the right eye was diagnosed and treatment was instituted. Despite treatment, the intraocular pressure kept increasing (up to 72 mm Hg overnight), and the clinicians decided to enucleate the right eye due to poor prognosis. After one month, and no response to treatment, the left eye was also enucleated. Gross Findings: Right and left eyes: The vitreous chamber was filled with a yellow, gelatinous exudate while the anterior chamber was filled with a translucent, gelatinous fluid. The retina appeared detached and embedded within the exudate present in the vitreous chamber.

Résumé :

Antibiotic susceptibility tests and restriction enzyme analysis (REA) of genomic DNA were performed to characterize the relationship between sources of isolates of yellow-pigmented enterococci. Antibiotic susceptibility tests were conducted with 10 therapeutic antibiotics and 54 isolates grouped by source (wild and other) depending on their origin. In three antibiotics, cephalothin, erythromycin, and vancomycin, there was a significant (p =< 0.05) association between susceptibility and source. Vancomycin resistance was significantly (p =< 0.001) higher in isolates from wild sources compared with that in isolates from other sources. The REA technique was performed on genomic DNA obtained from 17 Enterococcus mundtii isolates from: human (3), dog (4), horse (4), Canada goose (4), domestic goose (1), and Enterococcus mundtii ATCC 43186. A total of 12 different DNA types (A-L) were identified. Except for type D, 11 DNA types were unique and were distributed among dog (A, B, and C), human (E), horse (F, G, and H), Canada goose (I, J, and K), and domestic goose (L). Results suggested that vancomycin-susceptibility testing of yellow-pigmented enterococci may have potential value in the identification of sources of faecal pollution, especially when combined with traditional quantitative methods.Key words: yellow-pigmented enterococci, faecal pollution, antibiotic susceptibility, DNA typing.

Résumé :

Europe. Its distinctive black-yellow skin produces toxic alkaloids in the dorsal and parotoid skin glands. These alkaloids can cause clinical signs of intoxication and may lead to death of an animal after mucosal contact or ingestion of the fire salamander. Although there are many anecdotal reports on dog intoxication with the salamander, there are no published data available for that kind of intoxication. We assume that this is due to the fact that most dogs die after intoxication with toxic alkaloids of the fire salamander. This paper describes the clinical case of a dog which survived the intoxication after the contact with a fire salamander. Publication of this case report has a certain value to those people who deal with dogs because contacts of dogs with salamanders are not rare, but so far there is no publication in the literature on survival of a dog after biting a fire salamander.

Résumé :

In this case report, a diagnosis of pericardial mesothelioma in a four year old male German shepherd dog is described. The dog, which had anorexia, bloody diarrhoea, dehydration and depression and, died on day 10 of therapy, was systematically necropsied. At necropsy, approximately 1.5 litres of cloudy and bloody exudate were detected in the thoracic cavity. The parietal lamina of the pericardium was covered with multilobular nodular masses related with each other, 1 to 5 cm in diameter and grey-yellow in colour. There were proliferations characterised with grey-yellow colour and approximately 1 to 5 mm in length on visceral pleura. The presence of abscess foci with liquefied-centrum was observed when examining a section surface of the lung. The appearance of the oesophageal serosa, thoracic aorta and the thoracic section of the diaphragm were similar to pleura. A thickening was microscopically determined in the parietal lamina of the pleura and pericardium due to papillary proliferations consisting of cells similar to cubic or cylindrical epithelium. Severe lymphocyte and plasma cell infiltrations were observed in the pleural sections next to the lung. Neoplastic cells had nuclei with large eosinophilic granular cytoplasms and large vesicular and single nucleoli. Some neoplastic cells were determined to include intracytoplasmic vacuoles. The neoplastic cells contained some mitotic figures. It was observed that some tumour cells contributed to giant cell formation through integration. In periodic acid Schiff-haematoxylin (PAS-H) examinations it was determined that the pleural basal membrane maintained its integrity. Immunohistochemically, the tumour gave a weak positive reaction with anti-pancytokeratin staining while giving intense reaction with anti-vimentin staining.

Résumé :

ABSTRACT A 3yr old spayed female Brittany was referred with a cylindrical mass on the right side of her face. Three months earlier, a small stone embedded in the right parotid duct was noted and removed through a ductal incision by the referring veterinarian. At referral, the dog’s general physical condition was normal except for a cylindrical mass on the right cheek. Skull radiographs showed a possibly retained sialolith or dystrophic mineralization within the previous surgical site. Aspiration of the mass yielded a thick, yellow/tan, mucopurulent fluid. Cytology of the fluid demonstrated degenerative neutrophils without bacteria. The cylindrical mass was excised with a carbon dioxide laser. The caudal end of the mass was connected to the parotid salivary gland and the rostral one-third of the mass tapered to a point. The caudal end of the mass was ligated with 3-0 polydioxanone and excised immediately rostral to the ligation. Histopathology revealed that the mass was parotid duct ectasia. The dog completely recovered with some mild temporary facial paresis and had no recurrence of parotid duct ectasia at 4 mo follow-up. The case report describes a dog with an unusual parotid salivary duct ectasia caused by parotid duct sialolith removal.

Résumé :

Hemochromatosis was presumptively diagnosed using cytologic examination of liver tissue from an aged male Miniature Schnauzer. The dog was presented after receiving whole blood transfusion every 6–8 weeks for 3 years to treat pure red cell aplasia. The cytologic specimen contained clusters of hepatocytes with abundant intracytoplasmic gold-yellow pigment granules and clumps of extracellular, green-black, globular pigment, both interpreted to be hemosiderin. Histologic sections of liver revealed hepatocellular degeneration with bridging portal fibrosis, lobular atrophy, biliary hyperplasia, and diffuse, severe hemosiderin accumulation. Serum iron and ferritin levels, and dry-weight iron concentrations of liver, heart, and kidneys were markedly increased. Hemosiderin accumulation was confirmed in hepatocytes of cytologic and histologic specimens using Perl's Prussian blue staining. This report is the first description of transfusional hemochromatosis in a dog and is the first to describe its cytologic appearance in a veterinary patient.

Résumé :

An 18-month-old, intact female German shepherd dog was presented for evaluation of severe, frank hemorrhage from the vulva. A complete blood count, serum biochemical analysis, and urinalysis supported acute hemorrhage. Abdominal radiographs were unremarkable. Abdominal ultrasound demonstrated that the uterine body and cranial vaginal lumen were fluid-filled and contained hyperechoic, polypoid masses that were suspected to be blood clots. Exploratory laparotomy revealed a mildly enlarged uterus with a diffuse, cystic endometrium; significant amounts of blood and blood clots within the lumen; and several focal accumulations of yellow fluid presumed to be a purulent exudate. Histopathology confirmed severe, cystic, endometrial hyperplasia and pyometra complex.

Texte intégral

Résumé :

Predator scat analysis was used to infer the potential impact of wild dogs (Canis lupus dingo, C. l. familiaris and hybrids of the two) on threatened native terrestrial mammals in coastal and near-coastal southern New South Wales, Australia. Prey items recorded in wild dog scats were compared with those occurring in scats of the red fox collected at the same study sites. Six threatened mammal species were recorded in either wild dog or fox scats: eastern pygmy possum, grey-headed flying fox, long-nosed potoroo, southern brown bandicoot, white-footed dunnart and yellow-bellied glider. The prevalence of these threatened species in fox scats was significantly higher than in wild dog scats. Otherwise, wild dogs mostly consumed larger prey items such as swamp wallabies and wombats whereas foxes more heavily preyed on small mammals such as antechinus and rats. Our results suggest that foxes are the major threat to threatened mammal species in the study region. Land management agencies in south-eastern mainland Australia should therefore focus on controlling foxes for biodiversity gain.

Texte intégral

Résumé :

The aim of this study is to reveal the morphology of the lyssa in the cat and dog. Eight heads of adult healthy cats and eight heads of dogs of both sexes were used as materials. In the cat the lyssa, yellow coloured, had a helical appearance and its edge facing the oral cavity became sharp; in the dog the lyssa, pinkish white coloured, was more or less J-shaped. The whole body of the cat’s lyssa was buried among the intrinsic lingual muscles. In the dog, although aboral, two thirds of the lyssa were squeezed among the intrinsic lingual muscles, its cranial third was placed just under the mucosa to protrude slightly into the oral cavity. In both species, the whole body of the lyssa was determined to have been formed by the nearly adipose tissue in which occasional striated muscles existed. Moreover, in the middle third of the dog’s lyssa, dense striated muscle fibres were seen dorsally to the adipose tissue, and we also noticed with interest that the lyssa sheath embracing this part contained few muscle spindle-like structures. It was of interest that in the cat a pyramidal rod encircled by a fine capsule of connective tissue was attached to the ventral edge of the cranial third of the lyssa.

Résumé :

Renal interstitial cell tumor (RICT) is a rare renal sarcoma of dogs that arises from renal interstitial cells. Herein we describe a RICT in an 8-y-old female Labrador Retriever dog that died after a 2-d history of lethargy and disorientation. Grossly, soft white nodules of 1–10 mm diameter were present in the renal cortex and corticomedullary junction of both kidneys, left cardiac ventricular wall, and right cerebral hemisphere. A pale-white to yellow, firm, irregular mass effaced 80% of the right pulmonary parenchyma, involving mainly the cranial and middle lobes, and the adjacent tracheobronchial lymph nodes. Histologically, the renal, myocardial, and cerebral neoplasm consisted of interlacing bundles of stellate-to-spindle cells with eosinophilic vacuolated cytoplasm and round-to-oval nuclei with finely stippled chromatin. The mitotic count was 28 per 2.37 mm2. Alcian blue stain revealed an extracellular myxomatous matrix throughout the neoplasm. Neoplastic cells had cytoplasmic immunolabeling for vimentin and cyclooxygenase 2. The pulmonary and tracheobronchial neoplasm consisted of infiltrative nodules of cuboidal epithelial cells that had a moderate amount of eosinophilic cytoplasm and round nuclei with coarsely stippled chromatin. There were 5 mitoses per 2.37 mm2. Neoplastic cells had cytoplasmic and nuclear immunolabeling for cytokeratin AE1/AE3 and thyroid transcription factor 1, respectively. Morphologic and immunohistochemical findings were consistent with a RICT with cardiac and cerebral metastases, and a pulmonary carcinoma with tracheobronchial lymph node metastasis.

Résumé :

By the mid-1930s, U.S. coal miners could no longer tolerate company doctors. They objected to the misuse of preemployment and periodic medical examinations and to many other facets of employer-controlled health benefit plans. The rank-and-file movement for reform received critical assistance from the Bureau of Cooperative Medicine, which conducted an extensive investigation of health services in 157 Appalachian communities. This study not only substantiated the workers' indictment of prevailing conditions but illuminated new deficiencies in the quality and availability of hospital and medical care as well. The miners' union curtailed the undemocratic, exploitative system of company doctors and proprietary hospitals by establishing the United Mine Workers of America Welfare and Retirement Fund in 1946.

Résumé :

A study of interspecific interactions of European (Meles meles) and Asian (M. leucurus) badgers with other carnivores at badger setts was carried out in Darwin Reserve (European part of Russia) and in Ussuriisk Reserve (Russian Far East) in 2006-2011. We used camera traps for the registration of visits of carnivore mammals to the badger setts. Overall, 11 species were recorded. In both reserves, badger setts attract carnivore species during the whole year. Some predators visit badger setts regularly. The visitors can be divided into two groups: species searching shelter, or searching prey. The first group includes raccoon dog Nyctereutes procyonoides and red fox Vulpes vulpes. Raccoon dog was the most frequent visitor in both study areas (34 visits in Darwin reserve and 73 in Ussuriisk reserve). The second group includes lynx Lynx lynx and wolf Canis lupus in Darwin reserve and Asiatic black bear Ursus thibetanus, brown bear U. arctos, yellow-throated marten Martes flavigula aterrima and lynx Lynx lynx in Ussuriisk reserve. Smaller predators are also included into the second group because they can find prey at badger setts too: leopard cat Prionailurus bengalensis euptilura, sable Martes zibellina and Siberian weasel Mustela sibirica in Ussuriisk reserve and European pine marten Martes martes in Darwin reserve. No cases of aggressive interactions between the badgers and the visitors were recorded. But we noted two cases of change of sett owners and one case when raccoon dog removed dead badger cubs from the sett.

Résumé :

Abstract The ancestral homeland of Australian dingoes and Pacific dogs is proposed to be in South China. However, the location and timing of their dispersal and relationship to dog domestication is unclear. Here, we sequenced 7,000- to 2,000-year-old complete mitochondrial DNA (mtDNA) genomes of 27 ancient canids (one gray wolf and 26 domestic dogs) from the Yellow River and Yangtze River basins (YYRB). These are the first complete ancient mtDNA of Chinese dogs from the cradle of early Chinese civilization. We found that most ancient dogs (18/26) belong to the haplogroup A1b lineage that is found in high frequency in present-day Australian dingoes and precolonial Pacific Island dogs but low frequency in present-day China. Particularly, a 7,000-year-old dog from the Tianluoshan site in Zhejiang province possesses a haplotype basal to the entire haplogroup A1b lineage. We propose that A1b lineage dogs were once widely distributed in the YYRB area. Following their dispersal to South China, and then into Southeast Asia, New Guinea and remote Oceania, they were largely replaced by dogs belonging to other lineages in the last 2,000 years in present-day China, especially North China.

Résumé :

Field assessments of the health and welfare of kenneled dogs (Canis lupus familiaris) must be both accurate and rapid. In order to facilitate such evaluations, especially by individuals with limited training in canine behavior and welfare, a non-invasive tool was developed and pilot-tested utilizing dogs housed in commercial breeding facilities. Behavioral responses to approach were organized into three categories: red, indicating a fearful response to approach, green, indicating an affiliative or neutral response to approach, and yellow, indicating an ambivalent response to approach. The inter-rater reliability (IRR) of the tool when used by both behavioral experts and novice raters was evaluated with and without the presence of the dog’s familiar caretaker. Utilizing Cohen’s kappa, the experts had almost perfect levels of agreement (kappa=0.87). The novice raters had substantial levels of agreement (kappa=0.74). Overall, the dogs assessed by the novice raters had high proportions of green responses to approach and there was no statistically significant effect of caretaker presence on the proportion of green responses to approach. The assessment tool evaluated herein appears to have a high degree of IRR whether used by experts in canine behavior or by novice raters and may be a useful screening tool to determine the need for more in-depth welfare assessments.

Résumé :

Natural plant extracts often contain compounds that are useful in pest management applications. The essential oil of Eupatorium capillifolium (dog-fennel) was investigated for antifungal and insecticidal activities. Essential oil obtained by hydrodistillation of aerial parts was analyzed by gas chromatography (GC) and gas chromatography–mass spectrometry (GC/MS). The major components were determined to be thymol methyl ether (=methyl thymol) (36.3%), 2,5-dimethoxy- p-cymene (20.8%) and myrcene (15.7%). Antifungal activity of the essential oil was weak against the plant pathogens Colletotrichum acutatum, C. fragariae, and C. gloeosporioides in direct bioautography assay. The E. capillifolium oil showed promising repellent activity against the yellow fever mosquito Aedes aegypti, whereas the oil exhibited moderate activity against the mosquito's first instar larvae in a high throughput bioassay. Topical applications of the oil showed no activity against the blood-feeding female adults of A. aegypti. Eupatorium capillifolium essential oil showed a linear dose response between adult lace bug ( Stephanitis pyrioides) mortality and increasing oil concentration in an adulticidal activity bioassay. The dog-fennel oil was more potent than the conventional insecticide malathion. In conclusion, these combined results showed Eupatorium capillifolium oil is a promising novel source of a biological insecticide with multiple modes of action.

Résumé :

Infections by free-living amoebae can cause systemic disease in animals and humans. We describe the epidemiological, clinical and pathological aspects of disseminated acanthamoebiasis associated with canine distemper in three dogs of the semiarid region of Paraíba, Northeastern Brazil. Affected dogs developed progressive neurological and respiratory signs that progressed to death within in two to 20 days. Gross lesions were irregular and with yellow-reddish nodules randomly distributed in the lungs, heart, kidneys, spleen, lymph nodes, adrenals, and intestine. One dog had foci of malacia in the parietal cortex and another one in nucleus of brain basis. Histologically, pyogranulomas with areas of necrosis and hemorrhage in all organs affected were observed, associated with myriads of intralesional amoebic trophozoites. All three cases were concomitant canine distemper, that possibly triggered immunosuppression in the dogs. The diagnosis was performed through microscopic findings of infection by free-living amoebae and confirmed Acanthamoeba sp. by immunohistochemistry

Résumé :

In mammals, the pigment molecule pheomelanin confers red and yellow color to hair, and the intensity of this coloration is caused by variation in the amount of pheomelanin. Domestic dogs exhibit a wide range of pheomelanin intensity, ranging from the white coat of the Samoyed to the deep red coat of the Irish Setter. While several genetic variants have been associated with specific coat intensity phenotypes in certain dog breeds, they do not explain the majority of phenotypic variation across breeds. In order to gain further insight into the extent of multigenicity and epistatic interactions underlying coat pheomelanin intensity in dogs, we leveraged a large dataset obtained via a direct-to-consumer canine genetic testing service. This consisted of genome-wide single nucleotide polymorphism (SNP) genotype data and owner-provided photos for 3,057 pheomelanic mixed breed and purebred dogs from 63 breeds and varieties spanning the full range of canine coat pheomelanin intensity. We first performed a genome-wide association study (GWAS) on 2,149 of these dogs to search for additional genetic variants that underlie intensity variation. GWAS identified five loci significantly associated with intensity, of which two (CFA15 29.8 Mb and CFA20 55.8 Mb) replicate previous findings and three (CFA2 74.7 Mb, CFA18 12.9 Mb, CFA21 10.9 Mb) have not previously been reported. In order to assess the combined predictive power of these loci across dog breeds, we used our GWAS data set to fit a linear model, which explained over 70% of variation in coat pheomelanin intensity in an independent validation dataset of 908 dogs. These results introduce three novel pheomelanin intensity loci, and further demonstrate the multigenic nature of coat pheomelanin intensity determination in domestic dogs.

Résumé :

AbstractAn Entlebucher Mountain Dog (57 months old, case 1), a Labrador Retriever (24 months, case 2) and an Irish Soft-Coated Wheaten Terrier (31 months old, case 3) were presented for breeding soundness evaluation to the clinic. During semen collection in all 3 dogs, the pre-secretion and the sperm-rich fraction showed normal consistency and colour, whereas the prostatic secretion (3 rd ejaculate fraction) appeared strikingly yellow. In cases 1 and 2, a severely decreased sperm motility (asthenozoospermia) and an increased amount of abnormal spermatozoa (teratozoospermia), and in case 3, a moderately decreased total sperm count (oligozoospermia) were detected. Sonographical examination revealed abnormal findings regarding the uretero-vesical junction and ectopic ureters. Therefore it is concluded that urine admixture to the 3 rd ejaculate fraction may indicate the presence of ectopic ureters and may cause impairment of semen quality and fertility. The present cases raise questions regarding urospermia concerning: 1. its incidence in dogs in general and in connection with ectopic ureters and 2. its relevance as a cause of deficient ejaculate quality and subfertility or infertility.

Résumé :

Twenty-fourIxodes damminiticks (23 adults and one nymph) have been recovered in Nova Scotia since 1984. There has not been a systematic search for larvae and none has been identified. The recovery of the nymph from a road-killed yellow throat bird,Geothypis trichas,in late May 1990 supports the contention that migrating birds are bringing deer ticks into the province every spring. In March and April 1991, four adult deer ticks were identified, suggesting that these ticks had overwintered. These deer tick specimens indicate that it is possible thatI damminiis becoming established in Nova Scotia, if it is not already established. There has been no evidence for the existence ofBorrelia burgdorferiin the province. The spirochete was not cultured from 650Dermacentor variabilisticks, nor were antibodies detected in a small sample of feral rodents using an indirect fluorescent antibody test. A survey of 137 dog sera samples, analyzed by enzyme-linked immunosorbent assay, also proved negative. There has been no confirmed indigenous case of Lyme disease in Nova Scotia to date.

Texte intégral

Résumé :

Parasite drug resistance presents a major obstacle to controlling and eliminating vector-borne diseases affecting humans and animals. While vector-borne disease dynamics are affected by factors related to parasite, vertebrate host and vector, research on drug resistance in filarial parasites has primarily focused on the parasite and vertebrate host, rather than the mosquito. However, we expect that the physiological costs associated with drug resistance would reduce the fitness of drug-resistant vs. drug-susceptible parasites in the mosquito wherein parasites are not exposed to drugs. Here we test this hypothesis using four isolates of the dog heartworm (Dirofilaria immitis)—two drug susceptible and two drug resistant—and two vectors—the yellow fever mosquito (Aedes aegypti) and the Asian tiger mosquito (Ae. albopictus)—as our model system. Our data indicated that while vector species had a significant effect on vectorial capacity, there was no significant difference in the vectorial capacity of mosquitoes infected with drug-resistant vs. drug-susceptible parasites. Consequently, contrary to expectations, our data indicate that drug resistance in D. immitis does not appear to reduce the transmission efficiency of these parasites, and thus the spread of drug-resistant parasites in the vertebrate population is unlikely to be mitigated by reduced fitness in the mosquito vector.

Résumé :

The night pushes the sun down to the desert floor setting the horizon ablaze with washes or yellow, red, and orange. The smoke from our campfire stings our eyes while the flames make grotesque shadows of the cactus that circle our camp. Fifteen miles to the south we just barely make out the lights of the only tavern in the small town of Punkin Center in the Tonto National Forest, in central Arizona. Lee, a Navajo archaeologist and friend, passes me a bottle of Mad Dog in exchange for a cheap cigar left over from a friend's recent celebration of paternity. We sit in silence for several minutes before I finally ask Lee what he thought of a site we had "discovered" earlier in the day during a random transect of one of the United States Geographical Survey (USGS) sections of the Tonto National Forest quadrangle. The site, christened "Cerebral Pueblo" by one of the other archaeologists on our team who felt that the vein-like undulations of the vascular basalt used to construct the walls reminded him of the appearance of a human brain, was a small, fifty to seventy room community set atop a small hill, well away from nearby roads.

Résumé :

An 11-y-old spayed female German Shepherd was presented for a second opinion of ventral cervical swelling of 3-mo duration. On examination, the dog had significant dependent ventral cervical swelling. Enlarged lymph nodes with cystic changes and severe edematous facial swelling were noted on computed tomography. Fine-needle aspiration of the ventral cervical swelling revealed yellow-tinged fluid, with a predominance of lymphoid cells noted on cytologic examination. On cervical exploratory surgery, the left mandibular lymph node was surrounded by a large fluid pocket; biopsies of the lymph node were obtained. Impression smear cytology, flow cytometry, PCR for antigen receptor gene rearrangements, and histopathology were performed on samples from the left mandibular lymph node. Impression smear cytology revealed a population of atypical discrete cells. Flow cytometry identified a population of CD34+/CD45– large cells. A tumor of endothelial origin within the medulla of the lymph node was identified by histopathology, and lymphangiosarcoma was confirmed based on prospero-related homeobox gene 1 ( PROX1) immunoreactivity. Our study describes the challenges in the diagnosis of a rarely reported entity and highlights that neoplastic endothelial cells should be considered as a differential when high proportions of CD34+/CD45– cells are present in flow cytometry.

Résumé :

The purpose of this study was to describe the clinical presentation, imaging findings, and outcome in 10 dogs diagnosed with Rhinosporidium seeberi infections. Histopathology and cytology records were searched at a veterinary teaching hospital and a veterinary diagnostic laboratory to identify dogs with rhinosporidiosis. Medical records were reviewed for clinical, imaging, endoscopic, and surgical findings. Outcome was determined via evaluation of records and, where possible, telephone conversation with the primary care veterinarian and/or owner. Young to middle-aged large-breed dogs with an approximately equal sex distribution were represented. Unilateral signs predominated. Diagnosis was confirmed by histopathology in 9 cases, and cytology was diagnostic in only 1 of 3 cases. Histopathology was superior to cytology. Masses were soft tissue and contrast enhancing with no evidence of bony lysis on computed tomography (2 dogs). Direct or rhinoscopic (2 dogs) visualization revealed white to yellow pinpoint foci. Surgical resection (4 dogs) can result in long-term disease-free periods (up to 2659 days), although repeat surgery can be required. Dapsone was well tolerated in 1 dog, and relapse was not noted despite incomplete surgical resection (follow-up 749 days). Visualization of pale foci on a rostral intranasal mass in an endemic region should prompt consideration of rhinosporidiosis.

Résumé :

Sea snakes have a strong venom and when they bite can be fatal for humans, whereas snakes found in mangrove areas are weak venomous snakes and non-venomous snakes (McKay, 2006). The low understanding public aboutthe snakes has led to the assumption that any snakes found are dangerous, so research needs to be done in order to provide information on the types of venomous and non-venomous snakes present in coastal areas and around mangrove forest areas. This research was conducted from early January to the end of January located around Merta Sari Beach to Padang Galak. The method used is the method of cruising method is done by determining the habitat that is likely suitable for snake habitat (Asad et al., 2011). Data collected in the morning and at night, by capturing and identifying snakes found in situ refers to the snake identification titled '107+ Ular Indonesia' (Riza Marlon, 2014), and the book 'Reptiles and Amphibians in Bali 'By Mckay (2006). Based on the results of the study, snakes found around Merta Sari Beach and Padang Galak Beach numbered 61 individual snakes with two different families namely Colubridae and Elapidae. Snake species of the Colubridae family found are Dog-faced Water Snake (Cerberus rynchops) and the Elapidae family is the Erabu/Yellow-lipped Sea Krait (Laticauda colubrina) snake

Résumé :

Two species of rock-wallabies occur in New South Wales; the Yellow-footed Rock-wallaby Petrogale xanthopus in the far west and the Brush-tailed Rock-wallaby Petrogale penicillata in the east. Both species have contracted in distribution and abundance across their former range and are threatened in NSW. The P. xanthopus population in NSW now comprises only two sub-populations. Removal of large numbers of goats, thought to be the primary threat, has not halted the wallaby's decline. Fox and cat predation is now considered the major threat. Fox control is currently being conducted. P. penicillata has undergone a dramatic and continuing decline from being common throughout south-eastern Australia to currently being extremely rare in the southern and western parts of its range and found only in isolated colonies throughout the north of its range. Predation (particularly fox, but including dog and cat), once again, is considered the major threat. A recovery program has been commenced involving the media and wider community in locating extant colonies, as well as developing and implementing Population Management Plans. This program has documented further local extinctions and extremely low numbers of individuals in colonies in the southern and western parts of the range. While no surviving colonies are known between the Shoalhaven area and the Victorian border, there remain more and larger colonies in the north of the state.

Résumé :

Shrimp farming is one profitable sector of aquaculture and the Pacific white shrimp (Litopenaeus vannamei) is the most cultivated species worldwide. Nutrition is considered as one of the greatest challenges in shrimp farming due to its dependence on fishmeal (FM) as an ingredient in the feed. The main goal of the present work was to analyse if the substitution of FM by yellow mealworm (Tenebrio molitor) meal (TM) influences digestive enzyme expression, haemolymph parameters or the intestinal microbiota of shrimp juveniles. Shrimps (average initial weight 4.42±0.02 g) were fed five experimental diets where FM protein was gradually substituted by TM protein (0, 25, 50, 75, and 100%). The shrimps were fed four times per day with an amount equivalent to approximately 6% of their biomass for 42 days. The total haemocyte count, protein concentration and prophenoloxidase activity in the haemolymph were not significantly altered (P>0.05) when FM was substituted by TM. However, the agglutinating activity of shrimp serum determined against dog erythrocytes was higher in the shrimp group fed 25% TM. The absolute and specific activities of trypsin, chymotrypsin, lipase, α-amylase and the patterns of proteolytic activities were not affected by the dietary treatments. The shrimp gut bacterial microbiota profile was similar with the genera Pseudoalteromonas, Rubritalea, Ruegeria, Tenacibaculum, and Vibrio detected. These results show that TM is viable alternative for the replacement of FM, without any deleterious effects on expression of key digestive enzymes, gut microbiota or the immune system of the Pacific white shrimp.

Résumé :

Purpose. To analysis the multimodal imaging of a group of patients diagnosed clinically with atypical juvenile ocular toxocariasis (OT). Methods. In this case series study, we examined 9 young patients diagnosed with atypical OT. Routine ophthalmological examinations, fundus photography, optical-coherence tomography (OCT), fluorescein angiography (FFA), and B-mode ultrasound were performed. A questionnaire was used to record whether the patients were newly diagnosed and whether they had a history of exposure to a cat and dog. Aqueous humor and serum samples were taken for serological tests. Results. In all the patients, yellow-and-white dot-shaped lesions and perivascular white sheath were seen in the fundus. Heterogeneous changes including hyper-reflection in the disrupted neuroretina, hyper-reflection in the outer retinal layer, high-reflection mass on the surface of the neuroretina accompanied with reflective attenuation, and high-reflection mass involving the entire neuroretina or high-reflection mass in the vitreous body were noticed in OCT images. On FFA, seven of these patients (77.8%) showed leakage of fluorescein in the small- and medium-branch veins of the retina, and a “bristle-like” change indicated increased permeability of the vessels. B-mode ultrasound showed proliferative membranes and proliferative bands (33.3%), as well as spotted opacity in the vitreous (66.7%). The antibodies to Toxocara canis in the aqueous humor and serum were positive, and the Goldmann–Witmer coefficient was significantly increased in 6 out of 7 patients. Conclusions. Multimodality images are useful in the diagnosis of atypical juvenile OT, which could be easily overlooked and misdiagnosed.

Résumé :

The author analyzes the main types of plots of toponymic legends that have become wide-spread among the Khakass people and are of artistic and historical value. The toponymic space of the Khakass non-fairy prose is considered for the first time. Of particular interest are the toponymic legends about rivers and lakes. The toponymic legends about the mountains are no less diverse in their composition. Stories explaining the origin of the names of various ob-jects in the area play a significant role in the non-fairy prose. The research is based on the ma-terial of the volume “Khakas non-fairy prose” of the academic series “Monuments of Folklore of the Peoples of Siberia and the Far East” (2016). The study has identified the genre, textological and linguistic features of toponymic legends. Toponyms reflect the geographical features of the area. The legends contain terms reflecting flora and fauna of the steppe area and the rich world of nature. The image plays an important role in characterizing the topo-nyms and distinguishing between natural objects (the rivers Кim “Yenisei,” Agban “Abakan,” Ah Uus “White River,” Khara Uus “Black River,” Saraa adai kol “Lake of the Yellow Dog”). Toponyms can also include numbers with a specific meaning. Toponymic legends are consid-ered to be one of the most important sources for studying the material and spiritual culture of the people. Folklore toponyms are extremely rich and unique material, which can be used to investigate the toponymic system of the non-fairy prose of the Khakass people.

Résumé :

Abstract Several clinical studies of adoptive immunotherapy with genetically modified (GM) donor T cells infused after allogeneic hematopoietic cell transplantation (HCT) showed limited in vivo function of the transduced T cells. Factors that have hindered successful translation to clinical trials include insufficient preclinical data in large animal models and the need for prolonged cell culture - up to 2 to 3 weeks for optimal oncoretroviral (OR) vector transduction and selection of T cells. In preparation for in vivo studies of GM T cells to facilitate engraftment in the preclinical dog model of allogeneic HCT, we compared transduction protocols with OR and lentiviral (LV) vectors that aimed to decrease the duration of ex vivo T cell culture necessary for stable transduction while maintaining T cell alloreactivity. Vectors expressed enhanced yellow fluorescent protein (YFP) under a constitutive promoter. We compared vectors pseudotyped with viral glycoproteins (GP) including vesicular stomatitis virus (VSV)-G (LV only), feline endogenous virus (RD114), and chimeric RD114 envelope GP fused with murine leukemia virus-A cytoplasmic tail (RD114/TR). Although T cells transduced with LV vectors without prior mitogenic or allogeneic stimulation had 14% – 30% transduction efficiency of predominantly CD4+ cells, transgene expression was not sustained in CD8+ cells after allogeneic stimulation (n=3). In order to transduce T cells that could generate GM alloreactive cytotoxic T lymphocytes (CTL), freshly isolated T cells were stimulated with allogeneic dendritic cells (DC) for 4 days prior to transduction. VSV-G, RD114 or RD114/TR pseudotyped LV had primary transduction efficiency of 1.2 to 9% (n=5). Only cells that were transduced with RD114 or RD114/TR pseudotyped vectors maintained stable YFP expression after 2° allogeneic stimulation. Next, OR YFP vector pseudotyped with RD114 transduced 15 to 36% of DC allo-stimulated T cells (n=3). Both CD4+ and CD8+ cell populations were transduced (CD4+: CD8+ ratio 1.4:1) and the mean YFP fluorescence intensity was increased 0.6-log compared to LV vectors (p=0.01). We then evaluated T cells transduced with OR RD114 pseudotyped vector in vivo. To determine if short-term culture and transduction of T cells facilitated engraftment of CD3-depleted marrow in the DLA-haploidentical HCT model, donor T cells were collected on day −7 prior to HCT, cultured with recipient CD34+ derived DC, and on day −4 cells were transduced with RD114 pseudotyped YFP OR vector. To date, one dog was transplanted after 920cGy total body irradiation with 2x108 CD3+ donor cells/kg (1:1 CD4:CD8 ratio) 25% YFP expression and 2-log CD3-depleted marrow (4x108 TNC/kg). No post-grafting immunosuppression was given. Donor YFP transduced T cells were detected in the peripheral blood daily after HCT, and peaked on day +7. After engraftment on day +8, GVHD developed and the dog was euthanized on day +21 with all-donor chimerism. YFP+ T cells were detected in GVHD affected target organs. Previously, transduced donor CTL cultured for 4 weeks and transplanted with CD3-depleted marrow in this HCT model failed to engraft in all 5 dogs studied. These preliminary results support the hypothesis that short-term culture and transduction of donor T cells with RD114 pseudotyped OR vector maintain in vivo alloreactivity and facilitate engraftment of CD3-depleted marrow in MHC-mismatched recipients.

Texte intégral

Résumé :

Scats are often used to study ecological parameters of carnivore species. However, field identification of carnivore scats, based on their morphological characteristics, becomes difficult if many carnivore species are distributed in the same area. We assessed error rates in morphological identification of five sympatric carnivores’ scats in north-eastern Himalayan region of Pakistan during 2013–2017. A sample of 149 scats were subjected to molecular identification using fecal DNA. We used a confusion matrix to assess different types of errors associated with carnivore scat identification. We were able to amplify DNA from 96.6% (n = 144) of scats. Based on field identification of carnivore scats, we had predicted that out of 144 scats: 11 (7.6%) scats were from common leopard, 38 (26.4%) from red fox, 29 (20.1%) from Asiatic jackal, 37 (25.7%) from yellow throated martin, 14 (9.7%) from Asian palm civet and 15 (10.4%) from small Indian civet. However, molecular identification revealed and confirmed nine were scats (6.24%) from common leopard, 40 (27.8 %) from red fox, 21 (14.6%) from Asiatic jackal, 45 (31.25%) from Asian palm civet, 12 (8.3%) scats from small Indian civet, while 11 scats (7.6%) were found from Canis lupus Spp., three (2%) from dog, one (0.7 %) scat sample from porcupine, and two (1.4%) from rhesus monkey. Misidentification rate was highest for Asian palm civet (25.7%), followed by red fox (11.1%) and Asiatic jackal (9.7%) but least for common leopard scats (4.2%). The results specific to our study area concur with previous studies that have recommended that carnivore monitoring programs utilize molecular identification of predator scats. Using only morphological identification of scats can be misleading and may result in wrong management decisions.

Résumé :

The purpose of this study is a comparative study of dark and light cells of cortical parenchyma of the adrenal glands in mammals using light and electron microscopy. Material and methods. Cariometric and electron microscopic studies of the adrenal glands of 9 mammalian species have been carried out: Vulpes vulpes (fox), Vulpes lagopus (arctic fox), Canis familiaris (dog), Мartes zibellina (sable), Mustela vison (mink), Enhydra lutris (sea ape); Castor fiber (river beaver); Callorhinus ursinus (fur seal); Ovis aries (sheep). Serial paraffin sections were stained with hematoxylin and eosin, iron hematoxylin, Heidenheim azan, the PAS-reaction was used, the color of the trichrome-PAS and the tetrachromium-PAS. RNA was detected by the reaction of Brashe and gallocyanin by Einarsson. For the detection of lipids, frozen sections were stained with Sudan III + IV, Black Sudan. The number of dark and light cells in the cortex of the adrenal mink in different seasons was determined. On electron micrographs, the amount of lipid droplets and mitochondria in the fascicle of the adrenal cortex was counted. Results. In the cortex of the adrenal glands of mammals, dark and light cells are present. Dark cells, as far as accumulation of sudanophilic substances are converted into light cells, which with further accumulation of lipids undergo destructive changes. Also found are the dark dying cells of the adrenal cortex, characterized by densification of the cytoplasm, pycnosis of nuclei, accumulation of yellow-brown pigment. Dark cells have larger nuclei, give more intense reaction to RNA and ketosteroids and are more active secretory cells compared to light adrenocorticocytes. Electron microscopy in dark cells reveals a large number of mitochondria and a significant amount of lipid droplets are present. Light cells contain many lipid inclusions and few mitochondria.

Résumé :

Dissolved organic carbon (DOC) can limit food web productivity in lakes, potentially imposing resource limitation on fishes. We asked whether the abundance or early growth rate of three fish species was negatively related to DOC in 59 lakes in southern Quebec, Canada, where DOC concentrations ranged from 4 to 16 mg·L−1 for lakes containing walleye (Sander vitreum) and yellow perch (Perca flavescens) and from 2.6 to 9 mg·L−1 for lakes containing lake trout (Salvelinus namaycush). Estimates of abundance and growth rate were more precise for walleye and lake trout than for yellow perch because of differences in sample size. Abundance was negatively related to DOC for walleye and perhaps also for lake trout and yellow perch. Early growth rate was negatively related to DOC for walleye and lake trout, but not for yellow perch. These results support a growing body of literature suggesting that the productivity of fish populations may be negatively related to DOC concentrations in lakes.

Résumé :

Abstract. Based on four field investigations during 2003 and 2009 along the Yellow River mainstream, we examined the distributions, seasonal variations and transport features of organic carbon, with a focus on the impacts of human activities (reservoir construction and regulation scheme). The results showed that organic carbon transport processes in the Yellow River were different from other major rivers. Particulate organic carbon (POC) dominated in the Yellow River and it mainly originated from the Loess Plateau. POC levels in suspended sediment (POC %) ranged between 0.25% and 2.20% and more than 80% of POC concentrated in the particles with grain size smaller than 16 μm. On time scale, dissolved organic carbon (DOC) correlated negatively with discharges, indicating the influence of dilution effect. Along the river on spatial scales, DOC in the Qinghai-Tibet Plateau was closely related with temperature while DOC in the Loess Plateau showed the concentration effect, due to the abundant human input and the high ratio of evaporation to precipitation. Organic carbon in the Yellow River was very refractory and about 90% of POC and 70% of DOC cannot be degraded. Due to the high turbidity, the Yellow River suffers more impacts from the reservoirs in the transport of total suspended solids (TSS) and organic carbon. Ratios of DOC/POC ranged between 2.0 and 12 in the reservoirs and organic carbon was mainly in the dissolved from. POC deposited in the reservoirs of the Yellow River achieved 0.0033 Gt a−1, about 8 times its annual POC flux discharged to the ocean. During the 2008 Water and Sediment Regulation (WSR) period, DOC and POC fluxes was as high as 1.1 × 1010 g and 2.2 × 1011 g respectively, accounting for 35% of annual DOC flux and 56% of the annual POC flux to the ocean. Discharges and material fluxes to the ocean decline sharply due to the reservoir construction while large amounts of water and sediment are transported to the ocean in such a~short WSR period. These two human disturbances totally altered the processes of substance transport in the Yellow River, and may change the water chemical characteristics in the coastal zones.
