The aim of this study was to investigate Clostridium difficile and Clostridium perfringens in 82 diarrheic dogs positive for canine parvovirus type 2 (CPV). Enterotoxigenic C. perfringens type A was isolated from three (3.6%) dogs. One (1.2%) strain was also positive for NetE- and NetF-encoding genes, which are commonly associated with diarrhea in dogs. Toxigenic C. difficile was isolated from one animal (1.2%), which was also positive for A/B toxins. The present study identified C. difficile and C. perfringens infection in CPV-positive dogs. Further studies are necessary to clarify if clostridial infections may predispose or potentiate CPV-infection in dogs or vice versa.
本研究的目的是调查82只2型犬细小病毒（CPV）检测呈阳性的腹泻犬中的艰难梭菌和产气荚膜梭菌。从三只（3.6%）犬中分离出产肠毒素A型产气荚膜梭菌。一株（1.2%）菌株的NetE和NetF编码基因也呈阳性，这些基因通常与犬腹泻有关。从一只动物（1.2%）中分离出产毒素艰难梭菌，该动物的A/B毒素也呈阳性。本研究确定了CPV阳性犬中存在艰难梭菌和产气荚膜梭菌感染。有必要进一步研究以阐明梭菌感染是否可能使犬易患CPV感染或增强CPV感染，反之亦然。
