Antibiotic Susceptibility Patterns of Yersinia enterocolitica

Abstract
Antibiotic susceptibility patterns for Yersinia enterocolitica strains involving 10 different serotypes were analyzed and compared. All Y. enterocolitica were susceptible to colistin, gentamicin, kanamycin, neomycin and doxycycline, whereas all isolates displayed resistance to penicillin G, methicillin (derivative of penicillin), novobiocin, and clindamycin. The antibiograms for the Y. enterocolitica isolates were in some instances related to the somatic serotypes, especially serotype 0:8 for which the antimicrobial susceptibility pattern displayed the greatest disparity. By eliminating the antibiograms for the four serotype 0:8 strains, antimicrobial susceptibility patterns for atypical and typical strains were similar.
