Abstract:
:In C3H gnotobiotic mice, no significant difference was observed between the translocation of nine clinical isolates of enteropathogenic Campylobacter spp. and that of seven nonisogeneic Escherichia coli strains with or without various determinants of pathogenicity. In addition, there was no correlation found between the intensity of translocation of Campylobacter strains and the signs of invasiveness in the patients from whom the strains had been isolated.
