Antimicrobial susceptibilities of food-isolated strains of Yersinia enterocolitica, Y. intermedia, Y. frederiksenii, and Y. kristensenii
Abstract
The in vitro antimicrobial susceptibility of Yersinia enterocolitica and newly related species isolated from foods was examined. Only 4 of 375 isolates displayed resistance to non-ss-lactam antibiotics. MICs of ampicillin and carbenicillin determined by agar dilution with respect to 125 isolates showed the high susceptibility of Y. kristensenii and biovar 3 of Y. enterocolitica to carbenicillin (MIC for 90% of the strains, less than or equal to 8 micrograms/ml).
