摘要
A DNA probe endolabeled with digoxigenin by PCR was developed to detect and enumerate enterotoxigenic Clostridium perfringens in raw beef. After 2 h of hybridization, membranes were developed by using an anti digoxigenin-alkaline phosphatase conjugated antibody. The resulting chromogenic reaction allowed us to detect and enumerate less than or equal to 10 CFU of C. perfringens per g.
