Frequent Cross-Species Transmission Of Parvoviruses Among Diverse Carnivore Hosts, Andrew Allison, Dennis Kohler, Karen Fox, Justin Brown, Richard Gerhold, Valerie Shearn-Bochsler, Edward Dubovi, Colin Parrish, Edward Holmes Jan 2013

Frequent Cross-Species Transmission Of Parvoviruses Among Diverse Carnivore Hosts, Andrew Allison, Dennis Kohler, Karen Fox, Justin Brown, Richard Gerhold, Valerie Shearn-Bochsler, Edward Dubovi, Colin Parrish, Edward Holmes

Richard W. Gerhold Jr., DVM, MS, PhD

Although parvoviruses are commonly described in domestic carnivores, little is known about their biodiversity in nondomestic species. A phylogenetic analysis of VP2 gene sequences from puma, coyote, gray wolf, bobcat, raccoon, and striped skunk revealed two major groups related to either feline panleukopenia virus ("FPV-like") or canine parvovirus ("CPV-like"). Cross-species transmission was commonplace, with multiple introductions into each host species but, with the exception of raccoons, relatively little evidence for onward transmission in nondomestic species.


Geographic Variation In Nonmetric Dental Traits Of The Deciduous Molars Of Pan And Gorilla, Anna Hardin, Scott Legge Dec 2012

Geographic Variation In Nonmetric Dental Traits Of The Deciduous Molars Of Pan And Gorilla, Anna Hardin, Scott Legge

Scott Legge

Physical anthropologists often use nonmetric dental traits to trace the movement of human populations, but similar analysis of the teeth of nonhuman primates or the deciduous teeth is rare. Because nonmetric dental characteristics are manifestations of genetic differences among groups, they vary among geographically distant members of the same species and subspecies. We use 28 nonmetric dental traits in the deciduous molars to compare genetically and geographically distinct groups of extant African apes (Gorilla and Pan). Previous researchers have studied these traits in the adult or juvenile teeth of great apes and humans, and we score our observations according to ...

Richard W. Gerhold Jr., DVM, MS, PhD

Clinical, gross, and histopathology lesions and molecular characterization of Trichomonas spp. infection were described in two striped owls (Asio (Rhinoptynx) clamator), one American kestrel (Falco sparverius), two green-winged saltators (Saltator similis), and in a toco toucan (Ramphastos toco) from Brazil. These birds presented clinical signs including emaciation, ruffled feathers, abundant salivation and open mouth breathing presumably due to abundant caseous material. Gross lesions were characterized by multifocal yellow friable plaques on the surface of the tongue, pharynx and/or caseous masses partially occluding the laryngeal entrance. In the owls, the caseous material extended into the mandibular muscles and invaded the ...


Development And Validation Of A Taqman Real-Time Reverse Transcription-Pcr For Rapid Detection Of Feline Calicivirus, M Abd-Eldaim, Rebecca Wilkes, K Thomas, Melissa Kennedy Oct 2012

Development And Validation Of A Taqman Real-Time Reverse Transcription-Pcr For Rapid Detection Of Feline Calicivirus, M Abd-Eldaim, Rebecca Wilkes, K Thomas, Melissa Kennedy

Rebecca P. Wilkes DVM, PhD, DACVM

Feline calicivirus (FCV) is a common cause of upper respiratory tract disease in cats and is associated with interstitial pneumonia, oral ulceration and polyarthritis. Recently, outbreaks have involved a highly virulent FCV that leads to multisystemic signs. Virus isolation and conventional RT-PCR are the most common methods used for FCV diagnosis. However, real-time RT-PCR offers a rapid, sensitive, specific and easy tool for nucleic acid detection. The objective of this study was to design a TaqMan probe-based, real-time RT-PCR assay for detection of FCV. It was determined in our previous study that the first 120 nucleotides of the 5' region ...

Detection Of Feline Coronavirus In Captive Felidae In The Usa, Melissa Kennedy, S Citino, A Mcnabb, A Moffatt, K Gertz, Stephen Kania

Stephen A Kania

Feline coronavirus (FCoV) is an important pathogen of domestic and nondomestic Felidae. Investigation into the prevalence of FCoV in exotic Felidae has relied primarily on serology. The usefulness of genetic detection of FCoV using reverse transcription and nested polymerase chain reaction (RT/nPCR) for viral screening was investigated. Seventy-five biologic samples, primarily feces, from captive felids from 11 institutions were tested using PCR. Serum samples collected from all but 12 of these animals were tested for antibodies to type I and type II FCoV by indirect immunofluorescence. Twenty-four animals were positive using RT/nPCR for virus. Twenty-nine animals were seropositive ...

Sensitivity And Specificity Of A Nested Polymerase Chain Reaction For Detection Of Lentivirus Infection In Lions (Panthera Leo), H Adams, M Van Vuuren, Stephen Kania, A Bosman, D Keet, J New, Melissa Kennedy

Stephen A Kania

Feline immunodeficiency virus (FIV) is a lentivirus in the Retroviridae family that causes lifelong infection in domestic cats. The lentivirus of African lions (Panthera leo), referred to as FIVple, is endemic in certain lion populations in eastern and southern Africa. Lentivirus infection leads to immunologic dysfunction and immunosuppressive disease in domestic cats; however, little is known about the pathogenic effects of infection in lions, nor about the epidemiologic impact on free-ranging and captive populations. Whole blood and serum samples were collected opportunistically from free-ranging lions in Kruger National Park, Republic of South Africa (RSA). Whole blood and serum samples were ...

Deletions In The 7a Orf Of Feline Coronavirus Associated With An Epidemic Of Feline Infectious Peritonitis, Melissa Kennedy, N Boedeker, P Gibbs, Stephen Kania

Stephen A Kania

A population of Persian cats experienced an epidemic of feline infectious peritonitis (FIP) over 2 years. Twelve cases of FIP occurred in litters born during this period. Cats contracting FIP were all genetically related through the sire. Feline coronavirus (FCoV) genomic RNA was detected consistently in this study in biologic samples from adult cats, kittens suffering from FIP, and their siblings. Analysis of viral 7a/7b open reading frame (ORFs) were analyzed and revealed two distinct virus variants circulating in the population, one with an intact 7a ORF and one with two major deletions in the 7a ORF. The 7b ...


Detection Of Feline Coronavirus Infection In Captive Cheetahs (Acinonyx Jubatus) By Polymerase Chain Reaction, Melissa Kennedy, S Citino, T Dolorico, A Mcnabb, A Moffat, Stephen Kania Mar 2012

Detection Of Feline Coronavirus Infection In Captive Cheetahs (Acinonyx Jubatus) By Polymerase Chain Reaction, Melissa Kennedy, S Citino, T Dolorico, A Mcnabb, A Moffat, Stephen Kania

Stephen A Kania

Feline coronavirus genetic elements were detected by polymerase chain reaction from blood, fecal samples, and effusive fluid collected from 33 cheetahs in the U.S.A. Feline coronavirus-specific serum antibodies were also measured by indirect immunofluorescence. Ten cheetahs were positive for viral shedding by polymerase chain reaction, whereas 13 were seropositive by immunofluorescence. Results of serology did not consistently correlate with shedding of virus, and the capture antigen used for detection of feline coronavirus-specific antibodies had a significant impact on results. Testing of samples from one population over a 1-yr period indicated chronic infection in some animals. These relatively healthy ...

Detection Of Feline Coronavirus Infection In Southern African Nondomestic Felids, Melissa Kennedy, Stephen Kania, E Stylianides, H Bertschinger, D Keet, M Van Vuuren

Stephen A Kania

Feline coronavirus (FCoV) infects members of the Felidae family with results ranging from seroconversion with no disease to fatal feline infectious peritonitis (FIP). Infection of non-domestic felids with FCoV is of concern, particularly in endangered populations such as cheetahs (Acinonyx jubatus). In this investigation, we tested 342 animals in the Republic of South Africa and Namibia, including 140 animals from wild populations, for evidence of FCoV infection by serology and/or reverse transcription/nested polymerase chain reaction (RT/nPCR) on feces from 1999 through 2001. Past or current infection was evaluated. Of these, 195 animals had evidence of infection and ...

Assessment Of The Hemorheological Profile Of Koala And Echidna, Oguz Baskurt, Sonya Marshall-Gradisnik, Michael Pyne, Michael Simmonds, Ekua Brenu, Rhys Christy, Herbert Meiselman

Sonya Marshall-Gradisnik

Koala, a marsupial, and echidna, a monotreme, are mammals native to Australia. Blood viscosity (62.5-1250 s-1), red blood cell (RBC) deformability, RBC aggregation, aggregability and surface charge, and hematological parameters were measured in blood samples from six koalas and six echidnas and compared to adult human blood. Koala had the largest RBC mean cell volume (107.7±2.6 fl) compared to echidna (81.3±2.6 fl) and humans (88.4±1.2 fl). Echidna blood exhibited the highest viscosity over the entire range of shear rates. Echidna RBC were significantly less deformable than koala RBC but more ...

Haemorheology Of The Eastern Grey Kangaroo And The Tasmanian Devil, Michael Simmonds, Oguz Baskurt, Herbert Meiselman, Michael Pyne, Michael Kakanis, Ekua Brenu, James Keane, Rhys Christy, Sonya Marshall-Gradisnik

Sonya Marshall-Gradisnik

The blood of two Australian marsupials, the eastern grey kangaroo (Macropus giganteus) and the Tasmanian devil (Sarcophilus harrisii), has been reported to have greater oxygen-carrying capacity (i.e. haemoglobin content) when compared with that of placental mammals. We investigated whether alterations of blood rheological properties are associated with the increased oxygen-carrying capacity of these marsupials. Eastern grey kangaroos (n = 6) and Tasmanian devils (n = 4) were anaesthetised for blood sampling; human blood (n = 6) was also sampled for comparison. Laboratory measurements included blood and plasma viscosity, red blood cell (RBC) deformability, RBC aggregation and the intrinsic tendency of RBC to ...

Juergen P. Schumacher

Ranaviruses (genus Ranavirus) have been observed in disease epidemics and mass mortality events in free-ranging amphibian, turtle, and tortoise populations worldwide. Infection is highly fatal in turtles, and the potential impact on endangered populations could be devastating. Our objectives were to determine the prevalence of ranavirus DNA in blood and oral swabs, report associated clinical signs of infection, and determine spatial distribution of infected turtles. Blood and oral swabs were taken from 140 eastern box turtles (Terrapene carolina carolina) that were presented to the wildlife centers at the University of Tennessee (UT; n=39), Wildlife Center of Virginia (WCV; n ...

Dentoalveolar Abscess Variation Among Three Groups Of Chimpanzees (Pan Troglodytes Schweinfurthii, Pan Troglodytes Troglodytes, And Pan Paniscus), Scott Legge Dec 2011

Dentoalveolar Abscess Variation Among Three Groups Of Chimpanzees (Pan Troglodytes Schweinfurthii, Pan Troglodytes Troglodytes, And Pan Paniscus), Scott Legge

Scott Legge

The prevalence and pattern of periodontal and periapical dental abscess lesions are examined in 399 wild caught chimpanzee mandibles and maxillae from museum contexts (138 Pan troglodytes troglodytes, 152 Pan troglodytes schweinfurthii and 109 Pan paniscus). This study tests two predictions. First, canine size is the key determining factor in dental abscesses. Second, tooth breakage leads to higher frequencies of abscesses. Abscess frequencies were calculated for adult males (P. t. troglodytes 14.6%, P. t. schweinfurthii 16.3%, P. paniscus 15.4%) and females (P. t. troglodytes 15.7%, P. t. schweinfurthii 6.7%, P. paniscus 10.3%), while attempting ...


Widespread Occurrence Of Ranavirus In Pond-Breeding Amphibian Populations., J. Hoverman, Matthew Gray, Debra Miller, Nathan Haislip Dec 2011

Widespread Occurrence Of Ranavirus In Pond-Breeding Amphibian Populations., J. Hoverman, Matthew Gray, Debra Miller, Nathan Haislip

Debra L Miller

Ranaviruses are an emerging threat for many amphibian populations, yet their distribution in amphibian communities and the association of infection with possible stressors and species is not fully understood due to historically sparse surveillance. Agricultural practices that reduce the water quality of amphibian breeding habitats (e.g., cattle access to wetlands) and environmental stressors (e.g., lower temperatures) may contribute to ranavirus emergence. We tested larval amphibians for ranavirus infection across four seasons in farm ponds ( n=40) located in Tennessee, USA. Cattle at various densities were allowed access to half of the sampled ponds. Ranavirus infections were detected in ...
