| Abstract |
|
A study on the isolation of Yersinia from the feces of healthy pigs and the biotype and serotype and susceptibility to 16 antimicrobials was carried. Out of 853 pigs, Yersiniae were isolated from 349 pigs(40.9%). Of 349 isolates, 289 isolates(82.8%) were Yersinia enterocolitica and 54(15.5%) were Y kristensenii, 3(0.9%) were Y pesudotuberculosis and the rest 3(0.9%) were Y prederiksenii. Out of 289 isolates of Y enterocolitica, the predominants biotype was 3B comprising of 165 isolates(57.1%) and followed by biotype 2, comprising of 49 isolates(17.0%), bioptype 3A, comprising of 41 isolates(14.2%) and biotype 4 comprising of 23 isolates(8.0%). And the predominant serotype was 0 : 3 comprising of 231 isolates(79.9%) and followed by serotype 0 : 9 comprising of 42 isolates(14.5%) and 0 : 21 comprising of 10 isolates(3.5%). Y. enterocolitica were resistant to cephalothin(99%), novobiocin(99%), erythromycine(83%), ampicillin(83%) and carbenicillin(81%) and susceptible to amikacin(100%), colistin(100%), gentamicin(100%), kanamycin(100%), polymyxin B(100%), tobramycin(100%), chloramphenicol(99%), nalidixic acid(99%), neomycin(99%), streptomycin(99%) and tetracycline(99%). Most strains of biotype 2/serotype 0 : 9 were susceptible to carbenicillin(100%) and ampicillin(61%) but the other biotype/serotypes were resistant to these antibiotic. |
