The outer membrane proteins (OMPs) from 8 strains of Campylobacter, including 5 reference strains and 3 local strains, were isolated and examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The results showed that the population distributions of molecular weight of OMPs from different species and sources were alike based on the Rank Sum Test analysis. The number of bands of major OMP was around 2-3, the molecular weight of which varied from 33-68 kd. Moreover, three C. jejuni local strains isolated from patients in China showed common characteristics of OMPs to the reference strains. It is suggested that the OMPs of Campylobacter are of a conservative and stable structure.
