Fecal prevalence and diversity of endoparasites in shelter dogs and cats from East Tennessee.

Shelter animals are infected with a variety of endoparasites, and infections vary in severity and zoonotic potential. Data on parasite prevalence in Tennessee shelter animals are severely lacking. Fecal samples from 1111 dogs and 605 cats were collected from animal shelters from 2010 to 2023.

Pathology and parasitology of free-ranging coyotes from Tennessee and South Carolina.

Coyotes are exposed to many parasites and pathogens of veterinary and zoonotic concern. To assess the prevalence of the diseases caused by these microbes, we opportunistically obtained coyote samples from a variety of sources including a GPS collaring study, rabies testing facilities, wildlife resources agents, and road-side mortalities. We performed necropsies, serological testing, fecal flotations, and molecular analyses on coyotes from Tennessee and South Carolina.

Survey for spp. in wildlife in the eastern United States.

is a diverse genus of piroplasms that parasitize the red blood cells of a wide variety of mammals and avian species, including humans. There is a lack of knowledge on the species of carnivores and mesomammals in the eastern United States and the potential impacts of these species on the health of humans and domestic animals. We surveyed 786 wild mammals in the eastern United States by testing blood, spleen, and heart samples with PCR targeting the 18S rRNA region of apicomplexan parasites.

sp. meningoencephalitis in a captive bobcat.

A geriatric captive bobcat () was euthanized due to progressive anorexia and lethargy. Meningoencephalitis with intralesional apicomplexan organisms was identified histologically. With immunohistochemistry, the organisms were immunolabeled by anti- antibodies.

Hepatozoon spp. infection in wild canids in the eastern United States.

Background: Hepatozoon spp. are apicomplexan parasites known to cause musculoskeletal disease in a variety of animals. Two species are known to infect wild and domestic canids in the US: Hepatozoon canis and H.

Parasite Prevalence in Feral Swine (Sus scrofa) from the Great Smoky Mountains National Park, USA.

Feral swine (Sus scrofa) are an introduced species to the Great Smoky Mountains National Park (GSMNP), US, and serve as carriers of several diseases that are considered a threat to other wildlife, domestic animals, and humans. During 2013 and 2015, fecal samples from 67 feral swine from the GSMNP within both Tennessee and North Carolina, US, were opportunistically collected as part of a feral swine removal program and submitted to the University of Tennessee College of Veterinary Medicine, Knoxville, Tennessee, for parasite screening by centrifugal sugar flotation. Ten taxa from the phyla Acanthocephala, Apicomplexa, and Nematoda were identified: Ascaris spp.

Case report: Halicephalobus gingivalis in a Tennessee pony.

A 17-year-old female grade pony presented to University of Tennessee Veterinary Medical Center in May of 2021 for evaluation of multifocal, firm, sessile, circular lesions of various diameters on the ventrum and flank. The lesions had been present for two weeks at presentation. An excisional biopsy found numerous adult and larval rhabditid nematodes most consistent with Halicephalobus gingivalis.

Prevalence and Molecular Analysis of Hellbender (Cryptobranchus alleganiensis) Trypanosomes in Tennessee.

Populations of eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) have been declining for multiple decades because of a variety of stressors associated with anthropogenic habitat disturbance followed by riparian sedimentation. The influence of parasite-associated morbidity and mortality on wild hellbender populations is poorly understood. Research has detected widespread trypanosome infection in hellbenders in Virginia, US, with no other reported detections within the eastern hellbender's extensive range.

Growing and cultivating the forest genomics database, TreeGenes.

Forest trees are valued sources of pulp, timber and biofuels, and serve a role in carbon sequestration, biodiversity maintenance and watershed stability. Examining the relationships among genetic, phenotypic and environmental factors for these species provides insight on the areas of concern for breeders and researchers alike. The TreeGenes database is a web-based repository that is home to 1790 tree species and over 1500 registered users.
