Sero- and CPE-types of porcine enteroviruses isolated from healthy and diarrheal pigs: possible association of CPE type II with diarrhea.
Porcine enteroviruses (PEV) were isolated from feces of healthy and diarrheal domestic Japanese pigs, and examined for their serotypes. Each virus of the isolates corresponded not only to the Japanese version of the reference serotype, but also to its corresponding world version of the reference serotype. Twenty-two samples (75.9%) of 29 isolates from the feces of healthy pigs exhibited a characteristic of CPE I. On the other hand, 69.2% (27/39) of all diarrheal pigs showed a characteristic of CPE II. This would suggest the PEV with CPE II has a closer association with the enteric pathogenicity than that with CPE I.
