Case report: Disseminated larval trematodiasis caused by Clinostomum marginatum in a green tree frog (Hyla cinerea).

Clinostomum spp. are common parasites of piscivorous birds. Metacercaria are typically observed in the muscles or just under the skin of fish and rarely amphibians.

FATAL ACUTE HEMOLYSIS FOLLOWING TRIAZOLE THERAPY IN AFRICAN PENGUINS ().

Aspergillosis is a major cause of morbidity and mortality in penguins, with triazole antifungal drugs being commonly used for prophylaxis and treatment. This report describes 15 cases of fatal hemolysis associated with liquid itraconazole and voriconazole formulations administered to African penguins () from four institutions. All penguins underwent stressful events (e.

Anticoagulant rodenticide exposure and toxicosis in bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) in the United States.

Raptors, including eagles, are geographically widespread and sit atop the food chain, thereby serving an important role in maintaining ecosystem balance. After facing population declines associated with exposure to organochlorine insecticides such as dichlorodiphenyltrichloroethane (DDT), bald eagles (Haliaeetus leucocephalus) have recovered from the brink of extinction. However, both bald and golden eagles (Aquila chrysaetos) are exposed to a variety of other toxic compounds in the environment that could have population impacts.

Eastern Equine Encephalitis Virus in Visibly Affected Ruffed Grouse (Bonasa umbellus) in Michigan, Minnesota, and Wisconsin, USA.

Eastern equine encephalitis virus (EEEV) infects many avian species but has rarely been described in Ruffed Grouse (Bonasa umbellus). Between September and December 2019, 40 Ruffed Grouse, most in poor physical condition, were submitted to the Michigan, Wisconsin, and Minnesota (US) Departments of Natural Resources; eight were positive for EEEV.

Lesions associated with -like bacterium infection in a free-ranging, young-of-the-year raccoon from Prince Edward Island, Canada.

A young-of-the year, female raccoon was presented with clinical signs of weakness and tremors. The raccoon was euthanized, and autopsy findings included poor body condition, diffuse lymphadenopathy, and pale, firm kidneys with petechial hemorrhages throughout the renal cortex. Histologic lesions included systemic fibrinoid vascular necrosis and severe renal lesions, including lymphoplasmacytic interstitial nephritis and fibrinosuppurative glomerulonephritis.

Trichomonosis due to Trichomonas gallinae infection in barn owls (Tyto alba) and barred owls (Strix varia) from the eastern United States.

Trichomonosis is an important cause of mortality in multiple avian species; however, there have been relatively few reports of this disease in owls. Two barn owls (Tyto alba) and four barred owls (Strix varia) submitted for diagnostic examination had lesions consistent with trichomonosis including caseous necrosis and inflammation in the oropharynx. Microscopically, these lesions were often associated with trichomonads and molecular testing, if obtainable, confirmed the presence of Trichomonas gallinae, the species most commonly associated with trichomonosis in birds.

Necrotizing interstitial pneumonia and suppurative myocarditis associated with Bartonella henselae infection in three Florida pumas.

Three Florida pumas ( Puma concolor coryi) that had spent time in captivity prior to being released in the wild were found exhibiting respiratory signs and reluctance to move. All 3 pumas died shortly after immobilization, despite supportive veterinary care. Significant autopsy findings included necrotizing interstitial pneumonia, with pulmonary edema and hyaline membranes, and suppurative myocarditis.

Pituitary Abscesses in Four Free-ranging White-tailed Deer ( Odocoileus virginianus).

Although intracranial abscesses are a well-recognized cause of morbidity and mortality in free-ranging white-tailed deer ( Odocoileus virginianus), reports of pituitary abscesses in this species are scarce. Pituitary abscesses were the cause of neurologic disease in four adult white-tailed deer from the southeastern US in 2013-15.

Cellulitis caused by the Burkholderia cepacia complex associated with contaminated chlorhexidine 2% scrub in five domestic cats.

Isolates of the Burkholderia cepacia complex (BCC) are known as plant and human pathogens. We describe herein BCC infections as the cause of subcutaneous abscesses and purulent cellulitis in 5 cats. All cats were presented with an open wound, and 4 received standard wound care and empiric antibiotic therapy.

Eosinophilic meningoencephalitis associated with rat lungworm () migration in two nine-banded armadillos () and an opossum () in the southeastern United States.

, the rat lungworm, was the cause of neural larval migrans in two nine-banded armadillos () and one Virginia opossum () from the southeastern United States. Histologic findings in all three cases included eosinophilic meningoencephalitis with variable numbers of nematode larvae in the meninges or the neuroparenchyma. In two of the three cases, nematodes were extracted from brain tissue via a "squash prep" method.

A RETROSPECTIVE STUDY OF CAUSES OF SKIN LESIONS IN WILD TURKEYS (MELEAGRIS GALLOPAVO) IN THE EASTERN USA, 1975-2013.

Skin lesions of Wild Turkeys ( Meleagris gallopavo ) are a common cause of concern to wildlife biologists and the general public and are a frequent reason for submission to diagnostic laboratories. The purpose of this retrospective study is to evaluate the causes, occurrence, and epidemiologic patterns of skin lesions in Wild Turkeys in the eastern US. Skin lesions were diagnosed in 30% (n=199) of the 660 Wild Turkey samples submitted to the Southeastern Cooperative Wildlife Disease Study diagnostic service from 1975 to 2013.

Evaluation of rebound tonometry in non-human primates.

To determine the accuracy and reproducibility of intraocular pressure (IOP) measurements obtained with the TonoVet® rebound tonometer in cynomolgus macaques and to determine the effects of corneal thickness on measurements obtained by the TonoVet®. The anterior chambers of both eyes of anesthetized monkeys were cannulated with branched 23-G needles; one branch was connected to a vertically adjustable reservoir and the other to a pressure transducer. IOP was increased by 5 mmHg increments and then decreased by 10 mmHg decrements.
