Cantharidin toxicosis in 2 alpacas.

Two adult alpacas were presented for recumbency and reluctance to rise. Cantharidin toxicosis was suspected based on clinical and ancillary diagnostic findings. The diagnosis was confirmed by gas chromatography-mass spectrometry of gastric contents and urine.

Severe anemia associated with Mycoplasma wenyonii infection in a mature cow.

The clinical findings, diagnostic tests, and treatment of clinical anemia in a mature Angus cow infected with the hemoplasma Mycoplasma wenyonii are described.

Nonsteroidal anti-inflammatory drug-associated renal papillary necrosis in a white-tailed deer (Odocoileus virginianus).

Renal papillary necrosis was diagnosed during postmortem examination of a juvenile white-tailed deer (Odocoileus virginianus) from Oklahoma. The deer was surgically treated for a Salter Harris type II fracture of the proximal tibia of the left hind limb.

Detection of an antigenic group 2 coronavirus in an adult alpaca with enteritis.

Antigenic group 2 coronavirus was detected in a fecal sample of an adult alpaca by reverse transcription-PCR. The presence of alpaca coronavirus (ApCoV) in the small intestine was demonstrated by immune histochemistry with an antinucleocapsid monoclonal antibody that reacts with group 2 coronaviruses. Other common causes of diarrhea in adult camelids were not detected.
