title: Pathogenic synergy between Escherichia coli and Bacteroides fragilis: studies in an experimental mouse model.
abstract: An animal model is described for quantitative evaluation of pathogenic synergy between Escherichia coli and Bacteroides fragilis in which adjuvants were not required for abscess formation. Two sets of strains of E. coli and B. fragilis isolated from human wound infections were tested. Pathogenic synergy was observed in only one of the two combinations and was dependent on properties of E. coli.
