ABSTRACT
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. Despite medical treatment, neither alpaca survived. Blister beetle toxicosis has not been previously described in camelids. Challenges in treatment of affected ruminants or pseudoruminants are noted.
Toxicose à la cantharidine chez 2 alpagas. Deux alpagas adultes ont été présentés pour décubitus et une réticence à se lever. La toxicose à la cantharidine a été soupçonnée en se fondant sur des résultats diagnostiques cliniques et auxiliaires. Le diagnostic a été confirmé par chromatographie en phase gazeuse et spectromètre de masse du contenu gastrique et de l'urine. Malgré un traitement médical, les deux alpagas n'ont pas survécu. La toxicose aux cantharides n'avait pas été décrite antérieurement chez les camélidés. Les difficultés du traitement des ruminants ou des pseudoruminants sont signalées.(Traduit par Isabelle Vallières).

The clinical findings, diagnostic tests, and treatment of clinical anemia in a mature Angus cow infected with the hemoplasma Mycoplasma wenyonii are described. Mycoplasma wenyonii has been previously reported to cause clinical anemia in young or splenectomized cattle; however, infection has not been associated with severe anemia in mature animals.

A 7-hour-old alpaca was presented for lethargy and depression. The cria responded favorably to initial treatment but developed acute-onset dyspnea 48 hours later. Acute respiratory distress syndrome was diagnosed by thoracic imaging and blood gas analysis. The cria was successfully treated with corticosteroids and discharged from the hospital.

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. The animal was administered multiple nonsteroidal anti-inflammatory drugs (NSAIDs), including meloxicam, flunixin meglumine, and ketoprofen for pain management. At postmortem examination, gross lesions included a proximal tibial Salter Harris type II fracture with an associated fibrinonecrotizing myositis and bilateral renal papillary necrosis. Histologically, the kidneys exhibited coagulation necrosis of the renal medulla and renal papilla, thrombosis of renal blood vessels, and interstitial medullary edema. The gross and microscopic lesion coupled with the clinical history of multiple NSAID administration suggests NSAID-induced renal papillary necrosis.

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. We conclude that nutritional stress may have predisposed the alpaca to severe ApCoV infection.
