Spontaneous oronasal ejection of neoplastic and non-neoplastic nodules by 21 dogs, 2000-2024.

Spontaneous ejection of tissues from body orifices is rare in veterinary medicine. Here we underscore the diagnostic value of tissues spontaneously ejected from the nose or mouth of 21 dogs and submitted for histologic evaluation at 3 veterinary diagnostic institutions. Cases were retrospectively searched (2000-2024) from the Athens Veterinary Diagnostic Laboratory, Tifton Veterinary Diagnostic and Investigational Laboratory, and Antech Diagnostics web-based archive systems.

A divergent anatomic distribution of bovine lymphoma: time for an update.

Bovine leukemia virus-associated lymphoma (BLV-AL) is a significant neoplastic disease in cattle globally, resulting in substantial economic losses. Here we describe the anatomic distribution of lymphoma in adult cattle in 3 veterinary diagnostic laboratories (VDLs). Between 2001 and 2024, we retrieved 5,290 reports of bovine autopsies performed by these VDLs and 2,200 autopsies submitted by field veterinarians for diagnosis.

Retrospective study of laboratory-based surveillance of rabies in wild and domestic animals in the southern United States, 2010-2021.

We performed a retrospective study of all case submissions for the rabies virus (RABV) direct fluorescent antibody test (DFAT) requested of the Tifton Veterinary Diagnostic and Investigational Laboratory (Tifton, GA, USA) between July 2010 and June 2021. Submitted were 792 samples from 23 animal species from 89 counties in Georgia, and 4 neighboring counties in Florida, 1 in South Carolina, and 1 in Alabama. In 13 (1.

Granulomatous dermatitis caused by infection in a cow.

A 5-y-old, Piedmontese cow had a 4-mo history of ongoing development of skin masses. This was the only cow affected in a herd of 20 cows. Up to 12, hairless, red-to-black, raised nodules-to-plaques were distributed along the dorsum and tail head.

Proliferative strongyloidiasis in a colony of colubrid snakes.

are small rhabditid nematodes primarily associated with enteric disease in a variety of animal species, including reptiles. life stages were associated with a disease outbreak in a large breeding colony of snakes. Multiple and colubrids exhibited respiratory distress, anorexia, stomatitis, facial deformation, and waning body condition that resulted in death or necessitated euthanasia.

AUSTWICKIA CHELONAE IN A WILD GOPHER TORTOISE (GOPHERUS POLYPHEMUS) AND EVIDENCE OF POSITIVE SELECTION ON THE DIPHTHERIA-LIKE TOXIN GENE.

Austwickia (Dermatophilus) chelonae is a filamentous, Gram-positive Actinobacteria in the Dermatophilaceae family. It has caused fatal granulomatous disease in diverse captive reptile species on three continents, but its presence in wild or free-ranging populations was unknown. An adult female gopher tortoise (Gopherus polyphemus) was presented euhydrated, but cachectic and infested with ticks, with two firm, encapsulated masses over the cranioventral neck and right stifle.

Cytologic, histopathologic, and clinical features of granulomatous colitis in a French Bulldog.

A young French Bulldog was presented with clinical signs of chronic gastrointestinal disease, unresponsive to medical therapies. Parasite screenings and abdominal ultrasound failed to identify the etiology of the clinical signs. Cytologic evaluation of a rectal scraping sample diagnosed presumptive granulomatous colitis (GC) based on the presence of numerous macrophages with characteristic abundant, pink, granular cytoplasm, which showed an intense pink color when stained with periodic acid-Schiff.

Oral, Cloacal, and Hemipenal Actinomycosis in Captive Ball Pythons .

Ball pythons () are one of the most commonly kept and bred reptiles in captivity. In a large ball python breeding colony, a unique syndrome characterized by granulomatous inflammation of the cloaca and hemipenes (phalli) was observed in 140 of 481 (29.1%) breeding males, but only one of 1,446 breeding females.

A Novel Species Associated With Disseminated Granulomatous Inflammation in a Captive Eastern Hellbender ().

The genus is composed of ubiquitous, pigmented, saprotrophic fungi and includes both terrestrial and waterborne species. Though species are generally considered opportunistic pathogens, exophialosis can be an important cause of morbidity and mortality in aquatic and semi-aquatic species. Over a 6-year period, a captive 32-year-old male eastern hellbender (), was treated for recurring, slow growing, ventral midline cutaneous masses.
