Only the housed cows were affected, with 100% morbidity and 7 deaths within 24 hours of the onset of signs in the first cow affected.

Four approximately 6-week-old bobwhite quail (Colinus virginianus) were submitted for necropsy. The quail were from a production flock of approximately 30,000 in which there had been 15 deaths over 2 weeks.

A 3-year-old 19.4-kg spayed female Australian Cattle Dog (also known as Blue Heeler) was referred as an after-hours emergency because of abdominal effusion identified by the referring veterinarian when the dog was evaluated because of a history of vomiting, tremors, and agitation. The dog was involved with cattle herding and may have been kicked before the onset of signs

Clinical and Gross Findings

On presentation, the dog appeared anxious and was mildly tachycardic (144 beats/min; reference range, 100 to 130 beats/min), but the remaining vital signs were within reference limits. The abdomen had no external wounds but was distended,

Clinical and Gross Findings

On admission, the gelding was bright, alert, and responsive and had pink and moist mucous membranes, a capillary refill time of < 2 seconds, and vital signs, borborygmi, and digital pulses within reference limits.

A 22-month-old 21.8-kg spayed female Siberian Husky with a history of chewing on sticks and wood mulch was initially presented in February with the primary complaint of fetid breath of 3 days’ duration.

Clinical and Gross Findings

On oral examination, extensive sublingual necrotizing ulcerative stomatitis was observed along the right side and ventral aspect of the tongue (Figure 1). The lesion was suspected of being infected secondary to a penetrating wound, given the animal’s history of chewing on wooden items. The animal was anesthetized, and the lesion was debrided and closed. The animal was started

A 1-year-old male Narragansett turkey developed growth-like lesions on the face. This turkey was part of a backyard flock that also included chickens, ducks, and another turkey. The other turkey in the flock simultaneously developed similar cutaneous lesions on the neck.

Clinical and Gross Findings

Two days after the lesions were first noticed, both turkeys were brought to the referring veterinarian for evaluation and were prescribed oxytetracycline (200 mg, PO, q 24 h). Over the next 5 days, the growths progressed to cover much of the left side of the face. Both affected turkeys became lethargic and inappetent, and

History

A 7-month-old 9.69-kg sexually intact female mixed-breed goat was presented to the University of Tennessee College of Veterinary Medicine farm animal medicine and surgery service because of a 2-week duration of neurologic signs. The owner also reported that the goat had tested negative for serologic detection of caprine arthritis–encephalitis virus (CAEV). Upon arrival, the goat was recumbent and unresponsive. Due to progressive clinical deterioration and a poor prognosis, the goat was euthanized and immediately submitted for necropsy. The goat’s vaccination history was unknown.

Gross Findings

Postmortem examination revealed a diffusely wet brain that oozed abundant light clear fluid (edema).
