title: Bacteroides fragilis: an exogenous pathogen?
abstract: Thirteen strains of Bacteroides fragilis isolated from contaminated water or from cases of intestinal and non-intestinal infections were comparatively analyzed in order to detect a possible biological relationship among them. The observation of similar profiles among the two groups, regarding the capacity of inducing abscesses and some surface properties, may support the hypothesis that the species could also act as an exogenous pathogen.
