Abstract:

The assessment of heart rate variability (HRV) by linear methods in conjunction with Poincaré plots can be useful for evaluating cardiac regulation by the autonomic nervous system and for the diagnosis and prognosis of heart disease in snakes. In this report, we describe an analysis of HRV in conscious adult corn snakes Pantherophis guttatus (P. guttatus). The electrocardiogram (ECG) parameters were determined in adult corn snakes (8 females, 13 males) and used for HRV analysis, and the RR interval was analyzed by linear methods in the time and frequency domains. There was no sex-related difference in heart rate. However, significant differences were seen in the duration of the P, PR, and T waves and QRS complex; there was no difference in the QT interval. The values for the RR interval varied by 15.3% and 18.8% in male and female snakes, respectively, and there was considerable variation in the values for the high and low frequency domains. The changes in the time domain were attributed to regulation by the parasympathetic branch of the autonomic nervous system, in agreement with variations in the high and low frequency domains. The values for standard deviations 1 and 2 in Poincaré plots, as well as the values of the frequency domain, provide useful parameters for future studies of cardiac function in P. guttatus.

Abstract:

IntroductionCorn snakes are a very common pet reptile species, yet there is an absence of evidence-based literature standardising collection of ECG or detailing ECG deflection morphology in the normal animal. The authors describe a well-tolerated, reproducible technique and detail the cardiac cycle in terms of lead 2 equivalent waveforms and intervals.Animals29 adult corn snakes.Materials and methodsThis prospective study evaluated, under species-appropriate, standardised conditions, a technique for producing standard six-lead ECG tracings. Lead 2 equivalent cardiac cycles were described in detail and statistically analysed for sex, weight, length, heart rate and mean electrical axis.ResultsHigh-quality tracings demonstrated common ECG characteristics for this species, including no Q, S or SV waves, prolonged PR and RT intervals, rhythmic oscillation of the baseline, short TP segments, and a right displaced mean electrical axis. An influence of sex, weight or length on heart rate and mean electrical axis was not identified.ConclusionsTo the authors’ knowledge, this is the first study to describe a standardised technique for recording ECG in significant numbers of normal corn snakes. Ranges have been provided that may be of diagnostic value or form the basis for future development of reference intervals for this species.

Abstract:

A 3-year-old female red corn snake (Pantherophis guttatus) was presented for a three-week history of anorexia and decreased defecations. On physical examination, a soft midbody intracoelomic swelling was palpated. Transcutaneous coelomic ultrasound revealed a target-like mass on a transverse section of the stomach, suggesting the presence of a gastrointestinal intussusception. On exploratory coeliotomy, a double compounded esophagogastric and gastroduodenal intussusception was diagnosed and reduced surgically. A gastropexy was also performed to prevent recurrence. On histopathology, the gastric glandular mucosa showed moderate to marked proliferation. Diffusely lining the luminal surface of glandular epithelium and free within the lumen were a myriad of protozoa consistent with Cryptosporidium sp. A diagnosis of chronic proliferative gastritis due to Cryptosporidium sp. was made based on these findings. Intussusceptions are rare in reptiles and are infrequently reported in snakes. This is the first report of a double compounded intussusception in a nonmammalian species and the first report of an intussusception involving the stomach in a snake with gastritis due to Cryptosporidium sp.

Abstract:

The amniote egg was a key innovation in vertebrate evolution because it supports an independent existence in terrestrial environments. The egg is provisioned with yolk, and development depends on the yolk sac for the mobilization of nutrients. We have examined the yolk sac of the corn snake Pantherophis guttatus by the dissection of living eggs. In contrast to the familiar fluid-filled sac of birds, the corn snake yolk sac invades the yolk mass to become a solid tissue. There is extensive proliferation of yolk-filled endodermal cells, which associate with a meshwork of blood vessels. These novel attributes of the yolk sac of corn snakes compared with birds suggest new pathways for the evolution of the amniote egg.

Abstract:

Ophidiomycosis (snake fungal disease) is caused by the fungus Ophidiomyces ophiodiicola. As ophidiomycosis is difficult to study in free-ranging snakes, a reliable experimental model is needed to investigate transmission, pathogenesis, morbidity, and mortality, and the effects of brumation and temperature on disease development. Our objective was to develop such a model via subcutaneous injection of O. ophiodiicola conidia in red cornsnakes ( Pantherophis guttatus). The model was used to evaluate transmission and the effects of brumation and temperature in co-housed inoculated and noninoculated snakes. All 23 inoculated snakes developed lesions consistent with ophidiomycosis, including heterophilic and granulomatous dermatitis, cellulitis, and myositis, and embolic fungal granulomas throughout the liver and the coelomic connective tissue in 21/23 (91%). In the inoculated snakes, 21% of skin swabs, 37% of exuvia, and all liver samples tested positive by qPCR (quantitative polymerase chain reaction) for O. ophiodiicola. A post brumation skin swab from 1/12 noninoculated snakes that brumated in contact with inoculated snakes tested positive by qPCR, suggesting possible contact transmission. That snake had microscopic skin lesions consistent with ophidiomycosis, but no visible fungal elements. Of the 23 inoculated snakes, 20 (87%) died over the 70-day experiment, with ophidiomycosis considered the primary cause of death; 12 (52%) of the inoculated snakes died during brumation. Overall, this experimental model of ophidiomycosis reproduced skin lesions analogous to those of many natural cases, and internal lesions similar to the most severe natural cases. The study provides tentative experimental evidence for horizontal transmission in brumation, and offers a tool for future studies of this widespread snake disease.

Abstract:

RESUMO: Muitas espécies de animais silvestres de vida livre servem como reservatório de bactérias patogênicas que ameaçam a saúde humana e dos animais domésticos. Algumas bactérias, como Campylobacter jejuni, Campylobacter coli, Yersinia enterocolitica e Salmonella enterica, causam enfermidades em humanos e podem contaminar os animais domésticos e silvestres. O Núcleo de Reabilitação da Fauna Silvestre da Universidade Federal de Pelotas (NURFS-UFPel) soluciona uma demanda regional específica de atenção à fauna silvestre brasileira. O objetivo desse trabalho foi identificar a presença de Campylobacter jejuni, Campylobacter coli, Salmonella spp. e Yersinia enterocolitica em animais silvestres que se encontravam em processo de reabilitação. Foram coletadas amostras de fezes, com uso de zaragatoas estéreis, de 34 aves, 16 mamíferos e 23 répteis. Dos 73 animais amostrados, quatro (5,48%) albergavam Y. enterocolitica, sendo duas aves, um mamífero e um réptil. Salmonella e Campylobacter não foram isolados. Os perfis de bandas dos isolados de Y. enterocolitica analisados pela rep-PCR foram diferentes entre si. Esses resultados indicam que as cepas isoladas não estão relacionadas entre si, não possuindo uma origem comum recente. Vanellus chilensis, Turdus rufiventris, Didelphis albiventris e Pantherophis guttatus podem albergar Y. enterocolitica e eliminá-la nas fezes, oferecendo risco de disseminação desse micro-organismo no ambiente, além de constituírem possíveis fontes de contaminação para humanos e outros animais.

Abstract:

Introdução: Ooforectomia é o procedimento cirúrgico que consiste na retirada dos ovários e ovidutos dos répteis, sendo responsável pela esterilização do animal e possível aliado no controle de natalidade da Pantherophis guttatus, também conhecida como Corn Snake, espécie de serpente exótica, criada como pet, que vem sendo reproduzida e comercializada de maneira indiscriminada em território brasileiro. Objetivo: relatar o protocolo anestésico multimodal e a técnica cirúrgica de Ooforectomia em um exemplar de Corn Snake. Relato de caso: Após constatar estado de higidez, o animal foi contido quimicamente com a associação de Cetamina 1mg/kg, Midazolam 1mg/kg e Cloridrato de Nalbufina 2mg/kg, aplicados pela via intramuscular. A indução e manutenção anestésica foram feitas com anestésico inalatório Isoflurano, concebendo ao animal o máximo de conforto durante o procedimento cirúrgico. Com o animal em plano anestésico cirúrgico, foi realizado o bloqueio local infiltrativo em plano subcutâneo, na linha de incisão utilizando a Bupivacaína como anestésico local. A técnica cirúrgica de ooforectomia resume- se na extração total dos ovários e ovidutos através de uma celiotomia paraventral na altura dos órgãos em questão, incapacitando a reprodução do animal, alcançando o controle de natalidade e evitando possíveis problemas relacionados a ovipostura. Conclusão: A esterilização do espécime através da realização da técnica cirúrgica de ooforectomia, associadas aos cuidados trans e pós operatório são eficazes para a manutenção do estado de saúde do animal e controle populacional.

Abstract:

Abstract ContextAustralia has a high diversity of endemic vertebrate fauna. Yet, transnational human activities continue to increase the rate of transportation, introduction and establishment of new alien vertebrates in Australia, to the detriment of environmental and socioeconomic services. Eradication of invasive vertebrates is often costly and without guarantee of success; therefore, methods for detecting, intercepting and preventing the transport of alien species earlier in the invasion pathway provide substantial benefit. AimTo anticipate emergent threats to Australian biosecurity posed by the transport and introduction of new alien vertebrates over time. MethodsWe collated vertebrate interception data from various mainland Australian State, Territory and Commonwealth government reporting agencies, including data from a previously published study, at both pre-border and post-border stages from 1999 to 2016. Using generalised linear and generalised additive modelling, we predicted trends in interception frequency using predictors such as vertebrate taxa, detection category and alien status. Key resultsInterception frequency increased over time for all vertebrate classes, for pre-border stowaways and for post-border captive and at-large interceptions, with no saturation in the accumulation of new species over time. Five species were responsible for almost half of all incidents, of which red-eared sliders (Trachemys scripta elegans), boa constrictors (Boa constrictor) and corn snakes (Pantherophis guttatus) are prominent in Australia’s illegal alien pet trade. Rose-ringed parakeets (Psittacula krameri) are prominent in the legal alien cage-bird trade, which remains poorly regulated. Asian common toads (Duttaphrynus melanostictus) were frequently detected as stowaways, and most stowaway incidents originated from Southeast Asia, particularly Indonesia, via shipping. Data deficiency for pre-border incidents increased rapidly in 2015 and 2016. ConclusionsAustralia is subject to a persistent and increasing risk of alien vertebrate introductions and incursions over time, owing partly to emergent trends in the alien pet trade as well as increased global trade and tourism. ImplicationsThe future of Australia’s biosecurity remains dependent on stringent border security to prevent the arrival of novel species, but our findings also highlight the importance of ongoing management and control of high-risk species already present, often illegally, within Australia.

Abstract:

Life history, morphological variation, and basic biology of Pantherophis guttatus (Linnaeus, 1766), the Red Cornsnake, are not well known, particularly for the allopatric populations in Kentucky. To address some of the information gaps for this species, we report field observations, including activity patterns, reproduction, and meristics of P. guttatus in Kentucky. In 2003 and 2004 we conducted field surveys using drift fences, artificial cover, manual searching, and driving on roads and captured 101 P. guttatus in Edmonson and Hart counties, Kentucky. We found that artificial cover was the best method of detection with 77% of snakes captured using this method. Numbers of encounters peaked in April-May and August-September suggesting bimodal activity patterns similar to other colubrid snakes. Males had signifi cantly higher subcaudal scale counts than females while females had significantly higher ventral scale counts than males. We detected more individuals in 2003 than in 2004, most likely influenced by severe drought conditions in Kentucky during 2004. Size-class distribution of snakes was skewed towards large individuals (> 70 cm SVL). The absence of individuals in juvenile size classes (30 cm -70 cm) may be an artifact of lower detection probabilities for smaller size classes, different habitat use by juveniles, or may indicate low recruitment.

Abstract:

Abstract Trade-offs among performance traits are often difficult to detect despite the physiological and morphological incompatibilities that underlie disparate traits being well understood. However, recent studies that have corrected for individual quality have found trade-offs in human athletes performing various performance tasks. Few studies have found trade-offs among multiple performance tasks after correcting for individual quality in non-human animals because of the difficulty in motivating many animals to perform biomechanically different tasks. We examined potential trade-offs in maximal speeds among ten locomotor conditions that involved the utilization of different locomotor modes in cornsnakes (Pantherophis guttatus). Snakes were assessed during terrestrial lateral undulation, swimming, concertina movements (small and large width) and six conditions of arboreal locomotion (combinations of three perch diameters and two inclines). We found no trade-offs among locomotor conditions when analysing uncorrected speeds or speeds corrected for body condition. However, we found several trade-offs among modes and treatments for speeds corrected for individual quality. Terrestrial lateral undulation speeds were negatively related to speeds of concertina and two of the arboreal locomotion conditions. A trade-off between speeds on large and small perch diameters on a 30° incline was also detected and probably reflects potential conflicts in traits that maximize lateral undulation and concertina.

Abstract:

Reptil impor banyak diminati karena memiliki variasi warna yang sangat beragam. Penelitian ini mengenai jenis reptil eksotik yang ada di Yogyakarta baik yang dipelihara maupun yang sudah terlepas atau dilepas di alam dan bagaimana pula potensi dampaknya bagi spesies reptil lokal yang ada di Yogyakarta. Penelitian dilakukan di wilayah Kota Yogyakarta dengan melakukan survei di pasar hewan, petshop dan pemelihara reptil. Penelitian telah dilaksanakan dari tanggal 1 Agustus 2013 sampai 30 November 2013. Berdasarkan hasil survei pendataan reptil impor yang dipelihara di Yogyakarta, ditemukan 80 jenis yang terdiri dari satu jenis buaya kerdil (Paleosuchus palpebrosus), 14 jenis kadal (Sauria), 21 jenis ular (Serpentes), dan 44 jenis Kura-kura (Testudines). Reptil impor yang terlepas di alam ditemukan beberapa jenis, yaitu dua ekor Red Eared Slider (Trachemys scripta elegans), tiga ekor Chinese Soft-shelled Turtle (Pelodiscus sinensis) dan satu ekor Corn snake (Pantherophis guttatus). Red Eared Slider yang terlepas di alam dalam jumlah tersebut tidak dapat menimbulkan dampak negatif bagi reptil lokal, tetapi jika dalam jumlah yang banyak kemungkinan akan berpotensi sebagai kompetitor bagi bulus jawa (Amyda cartilaginea) dalam mencari makan. Chinese Soft-shelled Turtle yang terlepas di alam dalam jumlah tersebut kemungkinan akan berpotensi sebagai kompetitor bagi Amyda cartilaginea dalam mencari makan. Corn snake yang hanya satu ekor jika terlepas tidak akan menimbulkan dampak negatif bagi reptil lokal, tetapi jika jumlahnya terlalu banyak akan menjadi kompetitor bagi ular-ular lokal seperti ular koros (Ptyas korros), ular jali (Ptyas mucosa), ular kopi (Coelognathus flavolineatus), ular lanang sapi (Coelognathus radiatus), dan lain-lain, karena jenis mangsa yang sama.

Abstract:

Abstract Terrestrial organisms that use traveling waves to locomote must leverage heterogeneities to overcome drag on the elongate body. While previous studies illuminated how habitat generalist snakes self-deform to use rigid obstacles in the surroundings, control strategies for multi-component terrain are largely unknown. We compared the sand-specialist Chionactis occipitalis to a habitat generalist, Pantherophis guttatus, navigating a model terrestrial terrain–rigid post arrays on a low-friction substrate. We found the waveshapes used by the generalist were more variable than the specialist. Principal component analysis revealed that while the specialized sand-swimming waveform was always present on C. occipitalis, the generalist did not have a similarly pervasive low-dimensional waveshape. We expected the generalist to thus outperform the specialist in the arrays, but body slip of both species was comparable on level ground and in all trials the snakes successfully traversed the arena. When we further challenged the snakes to ascend an inclined lattice, the sand-specialist had difficulty maintaining contact with the obstacles and was unable to progress up the steepest inclines in the largest lattice spacings. Our results suggest that species adapted to different habitats use different control modalities—the specialist is primarily controlling its kinematics to achieve a target shape while, consistent with previous research, the generalist is using force control and self-deforms in response to terrain contacts. While both strategies allowed progress on the uninclined low-friction terrain with posts, the more variable waveshapes of the generalist may be necessary when faced with more challenging locomotor tasks like climbing inclines.

Abstract:

ABSTRACT Snake fungal disease (SFD) is an emerging skin infection of wild snakes in eastern North America. The fungus Ophidiomyces ophiodiicola is frequently associated with the skin lesions that are characteristic of SFD, but a causal relationship between the fungus and the disease has not been established. We experimentally infected captive-bred corn snakes (Pantherophis guttatus) in the laboratory with pure cultures of O. ophiodiicola. All snakes in the infected group (n = 8) developed gross and microscopic lesions identical to those observed in wild snakes with SFD; snakes in the control group (n = 7) did not develop skin infections. Furthermore, the same strain of O. ophiodiicola used to inoculate snakes was recovered from lesions of all animals in the infected group, but no fungi were isolated from individuals in the control group. Monitoring progression of lesions throughout the experiment captured a range of presentations of SFD that have been described in wild snakes. The host response to the infection included marked recruitment of granulocytes to sites of fungal invasion, increased frequency of molting, and abnormal behaviors, such as anorexia and resting in conspicuous areas of enclosures. While these responses may help snakes to fight infection, they could also impact host fitness and may contribute to mortality in wild snakes with chronic O. ophiodiicola infection. This work provides a basis for understanding the pathogenicity of O. ophiodiicola and the ecology of SFD by using a model system that incorporates a host species that is easy to procure and maintain in the laboratory. IMPORTANCE Skin infections in snakes, referred to as snake fungal disease (SFD), have been reported with increasing frequency in wild snakes in the eastern United States. While most of these infections are associated with the fungus Ophidiomyces ophiodiicola, there has been no conclusive evidence to implicate this fungus as a primary pathogen. Furthermore, it is not understood why the infections affect different host populations differently. Our experiment demonstrates that O. ophiodiicola is the causative agent of SFD and can elicit pathological changes that likely impact fitness of wild snakes. This information, and the laboratory model we describe, will be essential in addressing unresolved questions regarding disease ecology and outcomes of O. ophiodiicola infection and helping to conserve snake populations threatened by the disease. The SFD model of infection also offers utility for exploring larger concepts related to comparative fungal virulence, host response, and host-pathogen evolution.
