Antimicrobial Susceptibilities of the Genus Collinsella and Related Fecal Bacteria Isolated from Human Feces

Abstract

A many kind of antimicrobial agents were used for therapy. But the same time, the intestinal flora was disturbed by these therapies using antimicrobial agents. The MICs of nine antimicrobial agents were determined about Collinsella species and related bacteria, to determine what kind of antimicrobial agent effect to flora. All Collinsella strains were susceptible to some antimicrobial agents tested. A few agents of cephem and monobactum, however, have some effects to these strains. For the therapy, these agents are useful better than other agents are. Furthermore, it is clear that the susceptibility patterns are can be differential characters of three Collinsella species.
