Abstract

Faecal samples of Nigerian Indigenous breeds of pigs around Ife were cultured for species. The isolated and identified species were serotyped by agglutination technique on the basis of soluble heat stable antigen, using antisera prepared by Rabbit immunization. All Isolates from diarrhoic pigs were tested for sensitivity to eleven antimicrobial agents by the agar method.

Fifty-seven (57) isolates were recovered from diarrhoeic pigs while 10 isolates were got from non-diarrhoeic pigs. These isolates were identified as C. jejuni (18): C. coli (38); C. faecalis (6) while 5 isolates could not be characterised. From the serological studies, it was found that 14 of the 18 C. jejuni isolates belong to serogroup I; while the remaining 4 isolates belong to serogroup II. There was heterogeneity of other isolates. This probably indicates the importance of their serological investigations and shows that aggulutina on test can be effectively applied for studies in a herd of pigs in local areas.

Of the eleven antimicrobial agents tested, Septrin, Tetracycline, Chloramphenicol, Ampicillin, Gentamicin, Furalzolidine, and Erythromycin were active against most strains in that order. The Celphacloridine, Limcomycin, Sulphatriad and Metronidazric were relatively inactive.
