The sensitivity to drugs, the pH in the medium of extract from intestinal content (MEIC) and the utilization of carbohydrates in the strain isolated from multi-drug-resistant Enterococcus preparations (RP) were compared with those in the strain isolated from conventional Enterococcus prepations (CP). The RP showed higher resistance to penicillin and macrolide antibiotics than the CP, but less resistance to quinolone antibiotics. In the MEIC, the CP decreased the pH more markedly than the RP. Regarding utilization of carbohydrates, both the RP and CP had the similar patterns to the catabolisms of Enterococcus faecium, but different catabolisms were observed between RP and CP.
