Abstract:
Introduction. The class Cestoda is divided into two subclasses: the Cestodaria — unsegmented tapeworms, and the Eucestoda — true cestodes. The representatives of the orders Pseudophyllidea and Cyclophyllidae, which are part of the subclass of true cestodes parasitize in carnivorous mammals. At the same time, only representatives of the latter order parasitize in chiropterans. Data on the species composition and distribution of cestodes in the Rostov region have not been published yet. The list of bat species living in the Rostov region have been compiled previously. In this article, the authors study the cestode fauna parasitizing in chiropterans in the region under study. This review aims to analyse the current state of knowledge about the species composition of helminths parasitizing in bats in the Rostov region.Materials and Methods. The research materials have been obtained from the libraries and open access resources: PubMed (pubmed.ncbi.nlm.nih.gov), CyberLeninka (cyberleninka.ru), Google Scholar (scholar.google.com), BHL (www.biodiversitylibrary.org ), JSTOR (www.jstor.org), etc. Some data has been provided by the colleagues. Results. 17 species of cestodes of 4 genera, 1 family and 1 order can be found in 15 species of bats living in the Rostov region. Among them dominate the species of the genus Vampirolepis (11 species).Discussion and Conclusion. The results of the review carried out showed that maximum diversity of cestodes was found in one species of bats — the serotine bat (10 species). The smallest number of cestode species (1 per each) was found in the giant and lesser noctules. None of the cestode species found in bats in the Rostov region were recorded in companion animals or humans. However, some cestode species of the Hymenolepididae family, common in rodents, can infect the humans.

Abstract:
An ecological and physiological study of Common Eider (Somateria mollissima) nesting on the coast of Eastern Murman was carried out. The species composition of helminthofauna of birds and the quantitative parameters of the infection were studied. It is established that trematodes of the genus Microphallus, three species of cestodes - Lateriporus teres (Cestoda: Dilepididae), Fimbriarioides intermedia (Cestoda: Hymenolepididae), Microsomacanthus diorchis (Cestoda: Hymenolepididae) and one species of acanthocephalan - Polymorphus phippsi (Palaeacanthocephala: Polymorphidae) parasitized in the small intestine of Common Eider. It is shown that the activity of proteases decreased at the locations of F. intermedia and M. diorchis in the intestines of birds, with infestation with the acanthocephalan P. phippsi, on the contrary, increased. The activity of glycosides in the intestinal mucosa was reduced in comparison with the control values by infection cestodes M. diorchis. There was an increase in the values of hematological indices in infected individuals relative to the control parameters.

Abstract:
Tapeworms of domestic ducks (Anas platyrhynchos dom.) causing helminthiasis and serious damage to the hosts, cause economic damage in the poultry industry. Helminthological research devoted to the study of the parasite fauna, including tapeworms of domestic ducks, has been carried out in many countries. But there is no review information on the study of the helminth fauna of domestic ducks. We take our own materials and literature data and summarise the information on cestode parasites of Anas platyrhynchos dom., which have been recorded in the world until 2020. Each species is provided with the following data: scientific name, authority and year, intermediate and auxiliary hosts, habitat in the host body, collecting localities and geographic distribution, prevalence and intensity of infection and literature sources. Based on our own research and analysis of literature data, it was revealed that hitherto there are 419 species of helminths (Trematoda – 213, Cestoda – 89, Nematoda – 79, Acanthocephala – 11) recorded parasitising domestic ducks. The tapeworms found in Azerbaijan belong to four families (Dilepididae – 3, Hymenolepididae – 68, Davaineidae – 13, Diphyllobothriidae – 5). In Azerbaijan, 11 out of 89 species of helminths have been found in domestic ducks. Six of them were also noted in the course of our helminthological studies. The cestoda Diorchis inflata was recorded the first time in domestic ducks in Azerbaijan. Most species of cestodes were found in the north-eastern regions of Azerbaijan (Shabran – 11 species, Khachmaz – 6 species) and the southern region (Astara – 4 species). All of these areas are located on the shores of the Caspian Sea and are located on the annual migration route of wild birds involved in the spread of cestodes, which are considered biohelminths. Six species (Drepanidotaenia lanceolata, Hymenolepis apodemi, Hymenolepis diminuta, Ligula interrupta, Ligula intestinalis, Schistocephalus solidus) of cestodes parasitize both birds and mammals (D. lanceolata, H. diminuta in humans).

Abstract:
Objective of research: To study the activities and properties of nucleoside- diphosphatase (NDPase) in cestode Bothriocephalus scorpii. Materials and methods: Cestodes were homogenized with 10 vol. of extraction medium. NDPase was detected in mitochondria and microsomes with substrates (IDP, GDP, UDP). Inorganic phosphorus was determined by the method of Kochetov (1980). The effects of 10 anthelmintic drugs on the activity of NDPase were studied. Results and discussion: It was found that the mitochondrial and microsomal fractions of cestodes B. scorpii have nucleoside diphosphatase activity. The activity of nucleoside diphosphatase depends on substrates and Mg2+ ions. The impact of various effectors and ions (Ca2+, Mn2+, Zn2+) on enzyme activity was determined. Effects of 10 anthelmintic drugs on activity of nucleoside diphosphatase were studied. The anthelmintics Bitionol and Trichlorophen have been proved effective.

Abstract:
The aim of this study was to determine the distribution of parasites of the class Cestoda in farmed common carp from the cyprinid aquaculture facilities in Macedonia. The representatives of the class Cestoda occur most often during the winter (in 3.47% of examined fish), followed by spring (1.80%) and autumn (1.73%). They haven`t been identified during the summer. 20 fish out of 958 totally examined were infected with cestodes, with a mean intensity of 6.40, and a prevalence of 1.76%. In this study, the following parasite species were established: Caryophyllaeus fimbriceps, Bothriocephalus opsariichthydis and Ligula intestinalis (plerocercoid). Based on the total number of fish examined from cyprinid aquaculture facilities in Macedonia, the highest prevalence from the class Cestoda is determined by Bothriocephalus opsariichthydis (1.04%), followed by Caryophyllaeus fimbriceps and Ligula intestinalis with 0.55% each. The highest mean intensity with parasites of the class Cestoda is determined by Caryophyllaeus fimbriceps (9.40), followed by Bothriocephalus opsariichthydis (6.30) and Ligula intestinalis (3.60). The records of Caryophyllaeus fimbriceps in farmed common carp in the present study are considered as the first records for Macedonian aquaculture.

Abstract:
The brine shrimp genusArtemiaLeach (Crustacea, Branchiopoda), a keystone group in hipersaline wetlands all over the world, offers an excellent model to study species interactions (parasitism) and to explore “hidden fauna” (avian endoparasites). The present study is the first report on the parasite infection of the South American speciesArtemia persimilisfrom the Southern Chilean Patagonia (50°S–53°S). Samples were collected in Los Cisnes and Amarga lagoons, the two most austral populations of this crustacean described to date, during two seasons (spring and autumn). A total of 98 larvae of cestodes of the family Hymenolepididae (Cestoda, Cyclophyllidea) were found and identified as belonging to the following taxa:Confluaria podicipina(adult parasitic in grebes),Flamingolepissp. (a cestode parasite of flamingos),Fimbriarioides(?) sp. (adults of the species of this genus infect waterfowl and shorebirds) andWardiumsp. (definitive host unknown, most probably charadriiform birds). This is a new geographical record ofC. podicipinaand the genusFimbriarioidesfor the Neotropical Region, the latter being the most widely distributed species at both localities and seasons surveyed, and the only species recorded in autumn (April). Cestode community composition in Los Cisnes population was characterised by dominance ofFlamingolepissp., representing more than 65% of the total cestode species recorded, whereas in the Amarga population the most abundant parasite (>83%) wasFimbriarioides(?) sp. Significant seasonal variations were detected in Los Cisnes lagoon forFlamingolepissp. andC. podicipina, with exclusive presence of them in spring (November). Besides providing novel information on cestodes infection inA. persimilis,this study provides new data on the life cycle of cestodes of Neotropical aquatic birds such as South American flamingos and grebes. Our finding expands the knowledge on the biodiversity and population dynamics of extreme and unique environments from high latitudes (Patagonia) and makes evident the need of further taxonomical and ecological studies for better understanding the life cycles of avian helminth parasites in the Neotropics and the role of aquatic invertebrates in them.

Abstract:
Helminths of 12 fish species collected near the South Orkney Islands, West Antarctica were studied. In the whole sample of 115 fish specimens, we identified one species of Monogenea, 5 species of Trematoda, 4 species of Cestoda, 5 species of Nematoda, and 7 species of Acanthocephala. All cestode species, 3 species of nematodes, and 5 species of acanthocephalans were represented only by larval stages; fish are definitive hosts for the remaining 10 helminth species. Details of composition and structure of helminth communities were studied in 3 fish species: Chaenocephalus aceratus (Lönnberg, 1906), Champsocephalus gunnari Lönnberg, 1905, and Pseudochaenichthys georgianus Norman, 1937, each represented by more than 20 specimens in a sample. In these hosts, 19, 8, and 16 helminth species were found, correspondingly. In the helminth communities of C. aceratus and P. georgianus, the highest values of the infection prevalence and abundance were recorded for larval cestodes (Diphyllobothrium sp., Tetrabothriidea), nematodes (Pseudoterranova sp., Contracaecum sp.), acanthocephalans (Corynosoma spp.), as well as adults of the trematode Neolebouria georgiensis Gibson, 1976. The same trematode species and larval cestodes predominated in the helminth community of C. gunnari. All recorded species of parasites are generalists, each known from a range of fish hosts in Antarctica.

Abstract:
In many countries, poultry (including Anser anser dom.) play an important role in meeting population needs for meet. One of the factors that affect directly the meat quality and the industrial products obtained from domestic waterfowl are helminths, which cause diseases in their hosts. Helminthological research of the helminth fauna of domestic geese has been carried out in many countries, including Azerbaijan. Nevertherless, there is no general survey or species list of the world fauna of the domestic goose helminths. Tapeworms (Class: Cestoda) also parasitize the geese, causing them serious harm. Taking into account the relevance of the topic, we set the task to determine and systematize the species composition of tapeworms parasitizing the domestic goose (A. anser dom.) with the use of extensive literature data and our personal material. The species list is arranged in alphabetical order, families, genera and species of cestodes follow the nomenclature and classification by Khalil et al. (1994) and Olson et al. (2001), with updates by Kuchta et al. (2008) and Caira et al. (2014). We also took into account the classification adopted from the database of Fauna Europaea. Each species is provided with the following data: scientific name, author and year of description, synonyms, final, intermediate and auxiliary hosts, habitat in the bird body, collecting localities, geographic distribution, prevalence (PI) and intensity (II) of infection, and literature sources. An analysis of the worldwide literature and our personal data has established that 147 helminth species (Trematoda – 64 species, Cestoda – 33, Nematoda – 46, Acanthocephala – 4) are hitherto known from the domestic goose. The 33 tapeworm species of this list belong to five families (Dilepididae – 1 species, Hymenolepididae – 27, Mesocestoididae – 1, Paruterinidae – 1, and Diphyllobothriidae – 3). In Azerbaijan, 11 cestod species were found in the domestic goose. Six of them (Diorchis inflata, Drepanidotaenia lanceolata, D. przewalskii, Fimbriaria fasciolaris, Tschertkovilepis setigera, Ligula intestinalis) were registered in the course of our helminthological studies. The cestodes D. inflata and L. intestinalis were recorded in domestic geese in Azerbaijan for the first time. Five helminth species (Dilepis undula, Drepanidotaenia lanceolata, Ligula interrupta, L. intestinalis, Schistocephalus solidus) parasitize both birds and mammals (D. lanceolata in humans). Of these, two species (D. lanceolata and L. intestinalis) were found in Azerbaijan.

Abstract:
Information on cestode parasites in birds in Africa published in 1772–2022 in 177 works is summarised. The data of 434 cestode species belonging to 147 genera, 14 families and 3 orders are presented. For each species, the valid name, the synonyms used in the literature for Africa, bibliographic reference to the original records, names of the hosts and data on the geographical distribution on the continent are included. The cestode orders Dyphyllobothriidea and Tetrabothriidea are represented by one and seven species, respectively. The order Cyclophyllidea is represented by 426 species belonging to 146 genera and 12 families. The most species-rich families are Davaineidae (118 species), Hymenolepididae (105), Dilepididae (86) and Paruterinidae (50). In total, 333 species of birds belonging to 76 families and 27 orders have been recorded as hosts of cestodes in Africa. A host–parasite checklist is presented. The cestode complexes detected in avian orders are characterised by high levels of host specificity. The degree of knowledge of the avian cestode fauna of Africa is considered fragmentary and insufficient; it varies across countries, with the maximum number of species recorded in Egypt (112 species) and the Democratic Republic of the Congo (104 species). There are no records of avian cestodes for 19 African countries.

Abstract:
The demand for fish as a source of protein is on the increase. However, sustainable productivity by fish farmers is constrained by parasitic infections. Thus, an investigation was conducted on the prevalence of helminth parasites in some commercially important fish species of River Anambra, Nigeria. A total of 521 fishes belonging to 6 families (Claroteidae, Synodontidae, Mormyridae, Osteoglossidae, Bagridae, and Clariidae) and 20 species caught with hooks, nets, and local traps were examined using standard parasitological techniques. The overall prevalence was 23.80%. Fish samples belonging to 6 families had the following prevalence of infection: Bagridae (0.00%), Clariidae (2.11 %), Claroteidae (1.53%), Mormyridae (0.0%), Osteoglossidae (14.97%) and Synodontidae (5.18%). Helminth parasites recovered were: Weyonia species (4.65%), Weyonia youdeowii (15.97%), Weyonia synodontis (3.33%), Sandonella sandoni (37.41%), Polyonchobothrium clarias (17.98 %), Plerocercoid larva (13.33%) and unidentified cestode (35.47%) (Cestoda); Emoleptalea species (4.65%) (Trematoda); Procamallanus laeviconchus (2.72%), Dujardinascaris species (1.36%), Spirocamallanus species (3.99%) (Nematoda); Neoechinorhynchus species (24.61%), Tenuisentis niloticus (34.62%) and unidentified acanthocephalan (6.25%) (Acanthocephala). Weyonia species, Weyonia youdeoweii, and W. synodontis were recovered from synodontids only. Acanthocephalan, cestodes, nematodes and trematodes were found in decreasing order of abundance. The presence of trematode Emoleptalea sp in Clarias gariepinus is a new host record of the parasite for the geographical area.

Abstract:
The phylogenetic relationships within Neodermata were examined based on putative orthologous groups of proteins (OGPs) from 11 species of Monogenea, Trematoda, and Cestoda. The dataset included OGPs from BUSCO and OMA. Additionally, peptidases were identified and evaluated as phylogenetic markers. Phylogenies were inferred using the maximum likelihood method. A network analysis and a hierarchical grouping analysis of the principal components (HCPC) of orthologous groups of peptidases were performed. The phylogenetic analyses showed the monopisthocotylean monogeneans as the sister-group of cestodes, and the polyopisthocotylean monogeneans as the sister-group of trematodes. However, the sister-group relationship between Monopisthocotylea and Cestoda was not statistically well supported. The network analysis and HCPC also showed a cluster formed by polyopisthocotyleans and trematodes. The present study supports the non-monophyly of Monogenea. An analysis of mutation rates indicated that secreted peptidases and inhibitors, and those with multiple copies, are under positive selection pressure, which could explain the expansion of some families such as C01, C19, I02, and S01. Whilst not definitive, our study presents another point of view in the discussion of the evolution of Neodermata, and we hope that our data drive further discussion and debate on this intriguing topic.

The first data on marine fish parasites in Karadag nature reserve water area were published at the beginning of the 20th century. By the beginning of the 21st century, information on the fauna of cestodes in this area of the Black Sea included data on 19 species recorded in 24 fish species. However, taxonomy of this class of helminths has changed significantly over the last decade, and regional fauna needs to be revised. The aim of this work is to revise the species composition of fish cestodes in the water area of the Karadag nature reserve and adjacent areas on the basis of new data obtained and in accordance with current systematics of Cestoda. The material for this study was the collections of cestodes gathered by the staff of IBSS RAS Environmental Parasitology Department in the area of the Karadag nature reserve in different years, as well as our own collections of 1754 specimens of rays and teleosts of 53 species (2005–2018). The area studied is Black Sea coastal area from Meganom Cape to Ordzhonikidze village (southeastern part of Crimea), including various marine biotopes of the Karadag nature reserve. Voucher preparations of all types of cestodes used in this study were deposited in a subcollection of marine parasites of the World Ocean hydrobionts collection of IBSS RAS. Totally 20 cestode species were found in 17 fish species. Nine species, namely Progrillotia dasyatidis, Parachristianella trygonis, Dollfusiella aculeata, Rhinebothrium walga, Caulobothrium sp., Rhabdotobothrium sp., Acanthobothrium sp. 5, 7, and Anthocephaliidae gen. sp. 2., were reported for the common stingray Dasyatis pastinaca in the area under study for the first time. Cestodes belonging to the new species Acanthobothrium sp. 1, 2, 4 were found in the thornback ray Raja clavata. Of 19 species previously known in Karadag area, only 8 adult mature cestodes were recorded: “Bothriocephalus scorpii”, “B. gregarius”, Echinobothrium typus, Grillotia erinaceus, Prochristianella papillifer, Echeneibothrium variabile, Cairaeanthus ruhnkei, and C. healyae. In addition, larvae of the complex species “Scolex pleuronectis” were found in teleost fish. Larvae of cestode Progrillotia dasyatidis were found for the first time in the water area studied in 8 teleost fish species; this data contribute to the information on the participants in the life cycle of this helminth. Four cestode species, namely Hepatoxylon trichiuri larvae, Nybelinia lingualis larvae, Tetrarhynchobothrium tenuicolle, and Anthobothrium cornucopia, which were previously reported from this area, were not found in the present survey. Moreover, recent analysis of the occurrence and synonymy of species of orders Trypanorhyncha and Onchoproteocephalidea revealed that the previous identification of the cestodes in elasmobranchs as Grillotia (Christianella) minuta and Acanthobothrium coronatum, as well as identification of the cestodes in teleosts as Tentacularia sp. larvae, is incorrect due to the absence of their specific definitive hosts in the Black Sea. On the other hand, among representatives of Acanthobothrium spp. registered in D. pastinaca and R. clavata in Karadag water area, we found 7 morphologically different new taxa identified to the species level. The cestodes found belong to 6 orders: Bothriocephalidea, Diphyllidea, Trypanorhyncha, “Tetraphyllidea” relics, Rhinebothriidea, and Onchoproteocephalidea. The most species diversity of cestodes in both species of rays is registered among representatives of the orders Trypanorhyncha and Onchoproteocephalidea (5 species each), the least – in the orders Diphyllidea and “Tetraphyllidea” relics (1 species each). Thus, 12 species were added to the fauna of the cestodes parasitizing fish in Karadag area, and 8 of them are obviously representatives of new taxa.

Abstract:
In the course of an epidemiological survey of Echinococcus multilocularis (Leuckart, 1863), causative agent of alveolar hydatid disease, the autopsy of 154 red foxes, Vulpes vulpes (L.), captured in the Department of Cantal between November 1984 and February 1985 disclosed 144 cases of intestinal helminthiases. Helminths consisted of cestodes and nematodes; no trematodes were found. Multiple infestations were very frequent. Cestoda recorded consisted of the following species: Mesocestoides litteratus (Batsch, 1786) (40 cases; 26%), Taenia crassiceps (Zeder, 1800) (36 cases, 24%), Echinococcus multilocularis Leuckart, 1863 (23 cases, 14.9%), Taenia polyacantha Leuckart, 1856 (17 cases, 11.4%), Amoebotaenia paradoxa (Rudolphi, 1802) (8 cases, 5.2%), and Taenia pisiformis (Bloch, 1780) (2 cases, 1.3%). The following Nematoda were recovered: Uncinaria stenocephala (Railliet, 1884) (90 cases, 58.4%), Toxocara canis (Werner, 1782) (79 cases, 51.3%), Toxascaris leonina (Linstow, 1902) (39 cases, 25.3%), Trichuris vulpis (Froelich, 1789) (25 cases, 16%), Pterygodermatites affinis (Jaegerskioeld, 1904) (6 cases, 4%), and undetermined Trichostrongylidae (4 cases, 2.7%). Hosts were not examined for Trichinella sp. The cartography of each helminthiase revealed propitious areas of maintenance of the parasite. Echinococcus multilocularis had a very limited distribution compared with other taeniid species with a near-identical life cycle. Unknown ecological factors may have an adverse effect on the free stage (egg) of the cestode. The nematode Pterygodermatites affinis is reported here for the first time in France.

Abstract:
Cestodes from four badgers (Meles meles) and eight raccoons (Procyon lotor) were studied. The badgers and seven of the raccoons were taken from the wild near the city of Berlin, Germany. This paper is the first record of Atriotaenia incisa (Railliet, 1899) (Cestoda: Anoplocephalidae) from P. lotor in Europe. Atriotaenia incisa is redescribed and compared with morphological descriptions of the North American species Atriotaenia procyonis (Chandler, 1942), a common parasite of the raccoon in Canada and the United States. No morphological differences were found between the two species and it is suggested that they may be conspecific.

Abstract:
SUMMARYUsing biochemical genetic methods, we have distinguished 2 sibling species in the complex Bothrimonus nylandicus (Schneider, 1902), which infest 2 congeneric species of sole (Solea lascaris and Solea impar) on European coasts (Atlantic and Mediterranean). Neither of the parasite species is specific for either of the sole species, but one of them is present all year round, whereas the other is absent in the autumn and winter and only appears in the spring, subsequently disappearing at the end of the summer. Only S. impar lives in the Mediterranean, and is equally infested by both cestodes, whereas both species occur in the Atlantic and each of them is preferentially infested by 1 species of cestode. The shortness of the adult stage of the parasite in the definitive host and the presence of 2 life-cycles associated with competition between the 2 hosts in the Atlantic could be responsible for the biological differences observed and for maintaining the sibling species in sympatry.

Abstract:
SUMMARYThe complete nucleotide sequence of the mitochondrial genome was determined for the fish tapeworm Diphyllobothrium latum. This genome is 13 608 bp in length and encodes 12 protein-coding genes (but lacks the atp8), 22 transfer RNA (tRNA) and 2 ribosomal RNA (rRNA) genes, corresponding to the gene complement found thus far in other flatworm mitochondrial (mt) DNAs. The gene arrangement of this pseudophyllidean cestode is the same as the 6 cyclophyllidean cestodes characterized to date, with only minor variation in structure among these other genomes; the relative position of trnS2 and trnL1 is switched in Hymenolepis diminuta. Phylogenetic analyses of the concatenated amino acid sequences for 12 protein-coding genes of all complete cestode mtDNAs confirmed taxonomic and previous phylogenetic assessments, with D. latum being a sister taxon to the cyclophyllideans. High nodal support and phylogenetic congruence between different methods suggest that mt genomes may be of utility in resolving ordinal relationships within the cestodes. All species of Diphyllobothrium infect fish-eating vertebrates, and D. latum commonly infects humans through the ingestion of raw, poorly cooked or pickled fish. The complete mitochondrial genome provides a wealth of genetic markers which could be useful for identifying different life-cycle stages and for investigating their population genetics, ecology and epidemiology.

Abstract:
The European perch Perca fluviatilis L. serves as a host of different endohelminths of Trematoda, Cestoda, Nematoda, and Acanthocephala. Its natural range covers freshwater basins throughout much of Europe, including the Danube. Since information about endohelminths of European perch from this international river basin has been rather sporadic, the parasitological examinations of 700 perch from the central region of the Danube river basin in Slovakia were performed in October 2017 and April 2018. The larval stages of Triaenophorus nodulosus (Cestoda) were found in cysts located in the perch liver and adults of Proteocephalus percae (Cestoda) were isolated from the intestine. The larval stages of Eustrongylides sp. (Nematoda) and metacercariae of Clinostomum complanatum (Trematoda), both potential causative agents of fish-borne zoonoses, were found in the musculature. Spatial and seasonal differences in the occurrence of currently detected helminths were discussed with data on biological and environmental conditions of particular sampling site.

Abstract:
The aims of this study were to identify and to measure the prevalence of intestinal worm infections in free-ranging domestic cats in Bali. As many as 133 cat fecal samples were collected from Bali and preserved in sodium acetic formaldehyde solution. Coproscopy method (sedimentation concentration and flotation techniques) was used to identify the eggs of helminthes. Based on fecal examination, eggs of four helminthes species : Toxocara, Ancylostoma, Cestoda and Capillaria were identified. This result indicates the prevalence of intestinal worms in free ranging domestic cats were high, consisting of Toxocara sp (71.43%), Ancylostoma sp (37.59%), Cestoda (19.55%) and Capillaria sp (0.75%). Therefore, it is needed to conduct programs to reduce and eradicate that helminthes.

Abstract:
Previous studies suggest that cestodes (i.e., tapeworms) of the sister genera Symcallio and Calliobothrium attach in different specific regions of the spiral intestine of their triakid shark hosts, with species of Symcallio attaching in the anterior region of the spiral intestine and species of Calliobothrium attaching with a broader distribution centered around the middle of the spiral intestine. In the present study, we tested the generality of this pattern of site specificity in two additional species pairs: Symcallio peteri and Calliobothrium euzeti in Mustelus palumbes and S. leuckarti and C. wightmanorum in M. asterias. Finding that these cestodes also exhibit the aforementioned pattern, we investigated a series of functional explanations that might account for this phylogenetically conserved pattern of site specificity. The mucosal surface of the spiral intestine of both shark species was characterized, as were the attachment mechanisms of all four cestode species. Although anatomical differences in mucosal surface were seen along the length of the spiral intestine in both shark species, these differences do not appear to correspond to the attachment mode of these cestodes. We find that while species of Symcallio, like most cestodes, attach using their scolex, species of Calliobothrium attach with their scolex and, to a much greater extent, also with their strobila. Furthermore, attachment of Calliobothrium species appears to be enhanced by laciniations (flap-like extensions on the posterior margins of the proglottids) that interdigitate with elements of the mucosal surface of the spiral intestine. The role of proglottid laciniations in attachment in species of Calliobothrium helps reconcile a number of morphological features that differ between these two closely related cestode genera.

The cattle was investigated by the method of complete and incomplete helminthological autopsies. Cestodes, trematodes and nematodes were examined using the common methods. Larvae of trematodes and nematodes from dominant parasite species found in intermediate hosts (molluscs, insects, ants and dipterous) are also described in this paper. Results and discussion: 32 helminth species were identified in cattle from the central region of Uzbekistan: 5 species belong to the class Cestoda, 6 species — to the class Trematoda and 21 species — to the class Nematoda. Based on the nature of helminth localization in the host body, three groups of parasite communities were detected.

AbstractThe interaction between Bothriocephalus acheilognathi Yamaguti, 1934 (Cestoda)and pronephric lymphocytes of carp, Cyprinus carpio L. was studied by examining proliferation of lymphocytes isolated from both naïve fish and fish injected intraperitoneally with cestode extract. Lymphocytes from naïve hosts were stimulated to proliferate in the presence of the extract depending upon the extract protein concentrations; lower concentrations (0.01–0.05μg/ml) induced the greatest response, and immunosuppression occurred at higher concentrations. Significant differences were noted in fish that received intraperitoneal injections of parasite extracts. Five days post-injection, lymphocyte proliferation was significantly greater in these individuals compared with sham injected or untreated controls. This difference was reduced at 10 days post-injection, although the response was dependent on the concentration of the parasite extract. The possible significance of the observed stimulation/suppression of lymphocyte activity to establishment of the parasite in the wild is discussed.

Abstract:
Summary The systematic position of Quentinia mesovitellinica (Rêgo, 1967) (Cestoda, Cyclophyllidea) from the hystricomorph rodent Galea spixii (Wagler) (Caviidae) in Brazil is reevaluated based on published information. Quentinia mesovitellinica is generally thought to belong to the family Catenotaeniidae, being thus the only catenotaeniid cestode parasitizing hystricomorph rodents and also the only catenotaeniid in South America. However, the present study shows that Q. mesovitellinica differs fundamentally from Catenotaenia Janicki, 1904 sensu lato and other catenotaeniids with respect to several morphologic features, but shares these features with Monoecocestus Beddard, 1914 sensu Beveridge (1994), a genus in the family Anoplocephalidae sensu stricto (i.e. sensu Spasskii, 1951). However, Q. mesovitellinica is not assigned here to Monoecocestus, because the latter is a morphologically heterogeneous genus and will probably be split when subjected to a comprehensive phylogenetic and taxonomic analysis. Instead, Quentinia Spasskii, 1969 is considered a valid genus in the family Anoplocephalidae s. s. The morphologically closely related Monoecocestus eljefe Haverkost & Gardner, 2010 from Galea musteloides Meyen in Bolivia is assigned to Quentinia as Q. eljefe (Haverkost & Gardner, 2010) n. comb. An amended diagnosis is provided for Quentinia.

Тенденция увеличения видового состава гельминтов, общих для человека и животных, связана изменениями биоэкологических условий, ростом суммы эффективных температур, с частотой осадков в летний период, а также с малой эффективностью мер борьбы и несоблюдением сроков обработок животных. Гельминтологическое исследование фекалий человека проводили по методу Като. Видовой состав гельминтофауны животных, значения интенсивности и экстенсивности инвазий определяли методами Фюллеборна, полного и неполного гельминтологического вскрытия крупного и мелкого рогатого скота, буйволов и яков. Работу проводили на базе лаборатории паразитологии Прикаспийского зонального научно-исследовательского ветеринарного института. Применяли статистическую обработку по программе «Биометрия».

Abstract:
A total of 60 pigeon, Columba livia (25 males and 35 females) were examined to observe helminth parasite infection. All the birds were found to be infected by eleven species of helminth parasites: four species of trematoda: Echinostoma revolutum (15%) E. trivolvus (5%), Patagifer bilobus (5%), Ehinoparyphium recurvatum (8.33%); six species of cestoda: Hymenolepis columbae (63.33%), Raillietina echinobothrida (100%), R. bonini (43.33%), R. cesticillus (100%), Cotugnia celebesensis (68.33%), C. cuneata (100%); and one species of nematoda: Ascaridia columbae (28.33%). Females showed slightly higher intensity of infestation than the males. Trematode parasites were found in intestine and rectum, cestode parasites were found in duodenum and intestine, nematode parasite Ascaridia columbae was found in caeca. Oesophagus, crop, proventriculus, gizzard, gallbladder, liver, kidney and muscles were free of parasites. Considering among seasons highest intensity of infection was found in autumn.

Abstract:
AbstractThe seasonal cycle of the cestode Proteocephalus sagittus (Cestoda: Proteocephalidae) was studied for the first time in the stone loach Barbatula barbatula from the Haná River, Czech Republic. A total of 180 loaches were examined monthly from January to December 2001. The parasite occurred in loaches throughout the year but infection parameters differed significantly among seasons, with the highest values of prevalence and abundance from the late winter to the early summer. Parasite recruitment took place in the winter and early spring and the worms sexually matured in the late spring and early summer. In contrast to P. torulosus, the gravid worms of which laid eggs only at the end of the spring/beginning of the summer, gravid worms of P. sagittus were also found, although in low numbers, in the autumn and early winter. The rate of infection of loach with P. sagittus was neither dependent on the sex nor on the size of its fish host.

Abstract:
The genetic structure of populations of the fish cestode, Bothriocephalus acheilognathi collected from Bailianhe Reservoir (BLH), Changshou (CSH) and Liangzi (LZH) Lakes was investigated by using 8 microsatellite loci. A total of 108 adult worms were genotyped at each of the 8 loci. For the 3 populations, the mean number of alleles per locus ranged from 2·38 to 5·5, and the mean expected heterozygosity ranged from 0·432 to 0·559. The average polymorphic information content (PIC) was from 0·384 to 0·492. The significant Fis values indicated non-random mating within LZH and BLH populations. On the other hand, when samples were further classified into subpopulations at the level of host fish species, no or little heterozygote deficiency was detected at most loci, showing that cross-fertilization, predominantly, but not exclusively, must have occurred within the subpopulations. Microsatellite markers also revealed an unexpected high level of genetic differentiation, as measured by Rst and Nm values or by δu2 genetic distance among subpopulations from different hosts. Factors influencing the population genetic structure and the parasite host specificity are discussed.

Abstract:
Summary Trypanorhynch cestode larvae were found parasitizing specimens of dusky flounder Syacium papillosum (Linnaeus, 1758) in the Southeastern Gulf of Mexico (s-GoM). Plerocercoids were recovered from a total of 194 flatfish, embedded in the intestine and stomach wall. Trypanorhynch were identified using morphology and a molecular phylogeny using newly sequenced partial 28S (region D1-D3) ribosomal DNA in combination with data derived from other species of trypanorhynchs available from GenBank. Larvae representing three genera of trypanorhynch cestodes, Nybelinia Poche, 1926; Kotorella Euzet & Radujkovic, 1989 and Oncomegas Dollfus, 1929 were found in dusky flounder specimens in the s-GoM. These plerocercoids represent six species: Nybelinia sp. 1, Nybelinia sp. 2, Nybelinia sp. 3, Nybelinia sp. 4, Kotorella pronosoma (Stossich, 1901) and Oncomegas wageneri (Linton, 1890) Dollfus, 1929. All cestode specimens in this study represent new locality records for their respective species.

Abstract:
The Rhoptrobothriidae are one of the more enigmatic families of cestodes of elasmobranchs. Opinions on the taxonomic status of the family’s three original genera (i.e., Myzophyllobothrium, Rhoptrobothrium, and Myzocephalus) have varied over the 115 years since they were erected. Some authors have considered all three valid, others have considered Rhoptrobothrium to be a synonym of Myzopyllobothrium or a genus inquirendum, yet others have considered Myzocephalus to be a synonym of the phyllobothriid genus Thysanocephalum. All three genera were established for specimens collected from eagle rays off Sri Lanka. The erection of Mixophyllobothrium for two specimens from a cowtail stingray off India three decades ago added additional confusion to the situation, with some authors considering it valid and others a synonym of Myzocephalus. These disagreements stem largely from differences in interpretation of the complex morphology of the scolex of members of these genera. Furthermore, with the exception of Rhoptrobothrium comprising four species, each genus is monotypic. All but Rhoptrobothrium has not been considered in detail for nearly a century, largely because of a lack of available material. The taxonomic status of these genera is assessed here based on light and scanning electron microscopy, and molecular data generated from new material collected from eagle rays off Indonesian and Malaysian Borneo, Japan, Sri Lanka, and Viet Nam. Morphological work indicates that the genera differ largely only in the degree of folding of the four remi that extend from the cephalic peduncle. A molecular phylogeny based on sequence data for the D1–D3 region of the 28S rRNA gene, which include new data for eight specimens of four species, indicates that Myzophyllobothrium, Myzocephalus, and Rhoptrobothrium are not mutually monophyletic. The latter two genera and Mixophyllobothrium are considered synonyms of Myzophyllobothrium and five species are transferred to that genus. Myzophyllobothrium okamuri n. comb. is considered a species inquirendum. Myzophyllobothrium nagasawai n. sp. is described from Aetobatus narutobiei off Japan. Myzophyllobothrium narinari n. comb. is re-described based on newly collected cestodes from the type host and locality (i.e., Aetobatus ocellatus off Sri Lanka). Despite consisting of only a single genus, the family status of the group is retained in recognition of the unusual configuration of the scolex, which bears four biloculate bothridia and four remi extending from the cephalic peduncle. The ordinal placement of the family remains uncertain, but affinities with the Phyllobothriidea, rather than “Tetraphyllidea” are considered.
