A study on the isolation of Yersiniae from the feces of wild animals(mammals 376, birds 19 and reptiles 13) in zoo and the biotype and serotype and susceptibility of 12 antibiotics was carried. Out of 408 animals, Yersiniae were isolated from 28 animals(6.9%). Of 28 isolates, 27 isolates(96.4%) were Y. enterocolitica and 1(3.6%) was Y. kristensenii. According to the species, 25(6.6%) of Y. enterocolitica and 1(0.3%) of Y. kristensenii were isolated from 376 mammals, 2(15.4%) of Y. enterocolitica from 13 reptiles but not isolated from 19 birds. According to the eating pattern, 8(5.2%) of Y. enterocolitica were isolated from 155 carnivora, 13(10%) of Y. enterocolitica from 123 herbivora, and 6(4.9%) of Y. enterocolitica and 1(0.8%) of Y. enterocolitica from 123 omnivora. Out of 27 isolates of Y. enterocolitica, all were biotype 1. And predominant serotype was 0:21(40.7%), and 0:5(37.0%), 0:6(11.1%), 0:1(3.7%), 0:9(3.7%) and untypable(3.7%). Yersiniae isolated from zoo animals were resistant to cephalothin(100%), ampicillin(96.4%), carbenicillin(96.4%) and tetracycline(14.3%) and streptomycin(3.6%) and susceptible to chloramphenicol(100%), colistin(100%), gentamicin(100%), kanamycin(100%), nalidixic acid(100%), polymyxin B(100%) and tobramycin(100%). The predominant multiple resistance pattern was Am-Cf-Cb(82.1%), and Am-Cf-Cb-Te(10.7%) and Am-Cf-Cb-Te-Sm(3.7%).
