Outbreak of canine parvovirus 2b and Clostridium difficile infection in Asian small-clawed otters.

ABSTRACT: A concurrent outbreak of infection by canine parvovirus 2b (CPV-2b) and Clostridium difficile producing A and/or B toxins occurred in Asian small-clawed otters (Amblonyx cinereus). The 5 clinically affected otters were 6- to 24-mo-old intact females that had severe diarrhea, dehydration, were acutely comatose, and died 1-4 d after the onset of clinical signs. Postmortem examination was performed in 3 of 7 otters. Macroscopically, the small intestine was diffusely reddened and contained red-to-brown, malodorous, watery digesta without formed feces (3 of 3). Histologic examination identified loss of enterocytes and necrosis of crypt epithelial cells. Denuded villi were often covered by mixed bacterial colonies with a predominance of gram-positive cocci to short rods in addition
