    Abstract:
    Postmortem investigation was performed on 54 scouring (soon after onset of diarrhea) and 23 healthy suckling piglets. The animals were 1 to 4 weeks of age and were collected from 27 herds. In 21 herds diarrhea had been observed for a long time in piglets in this age group. Coccidia were found in 34 piglets, rotavirus in 2, cryptosporidia in 2, enterotoxigenic E. coli in 6, attaching and effacing E. coli in 1, Cl. perfringens type C in 1, Campylobacter coli in 53 and C. hyointestinalis in 8 piglets. Some of these microorganisms were isolated from healthy piglets as well. TGE- and PED-Virus antigen, as well as Salmonella were not recovered from any of the pigs. Results of the histopathological and enzyme histochemical investigations were in agreement with data from the literature. They confirmed and emphasized the role of coccidia as enteropathogenic agents in the animals examined. On the other hand evidence was shown, that C. coli is non-pathogenic. The role of C. hyointestinalis could not be fully elucidated. At least one sort of enteropathogenic agent was detected in about 68% (n = 37) of the scouring pigs or was present in 81% (n = 17) of the herds, respectively.
