Identification of Campylobacter jejuni and Campylobacter coli from waste water by SDS-disc-page of whole cell protein.

Analysis of the electrophoretic profiles of whole cell proteins of Campylobacter strains from waste water was used to differentiate C. jejuni from C. coli. The results show, that biotyping of campylobacters from waste water may results in a false species differentiation. Some of the Campylobacter strains originally typed as C. coli, were proved to be atypical C. jejuni strains. Therefore, in addition to biotyping and serotyping, electrophoretic typing is recommended to ensure correct identification of Campylobacter, especially from environmental sources.
