Distribution and characterization of yersinia enterocolitica isolated from imported pigs and dogs I. Biotypes, Serotypes and Antibiotic Susceptibility

A survey was conducted to see the distribution and characterization of Yersinia enterocolitica in imported pigs and dogs. 1. Out of 886 pigs and dogs, 205 strains of Yersinia enterocolitica were isolated from fecal samples of the pigs and dogs. One hundred twenty-seven strains(23.6%) and 78 strains(22.4%) Yersinia enterocolitica were isolated in pigs and dogs. 2. Two hundred five isolates of Yersinia enterocolitica the predominant biotype were 3B(47.3%) and followed by 3A(19.5%), 3(12.6%), 1(11.2%) and 2(9.2%). 3. Two hundred five isolates of Yersinia enterocolitica the belonged to serotype 0:3(70 strains, 34.1%), 0:8(57 strains, 27.8%), 0:5(27 strains, 13.1%), 0:1,2(26 strains, 12.6%), 0:9(10 strains, 4.8%) and untypable(6 strains,7.6%), among them strains of serotype 0:3 and 0:8 were predominant. 4. Yersinia enterocolitica were susceptible to gentamicin(100%), kanamycin(100%), tobramycin(100%), nalidixic acid(99.5%), chloramphenicol(98.5%), tetracycline(97%) and resistant to cephalothin(99.0%), erythromycin(95.1%) and ampicillin(94.1%).
