Detection of virulence genes in Campylobacter jejuni (Thai)

Abstract

Campylobacter jejuni is a major cause of bacterial diarrhea in many countries. It was reported to be the
most commonly found in poultry and poultry products. This research studied the prevalence of major virulence
genes including cad F,cdt A,cdt B andcdt C in 22C. jejunistrains isolated from162 samples of chicken feces,
chicken sample, wild bird carcasses and pork by polymerase chain reaction technique. The 22 strains were
selected from C. jejunipositive samples based on location.cadF,cdtA,cdtB and cdt C were found in 21
(96%), 15 (69%), 19 (87%) and 21 (96%) isolates, respectively. 16 strains had all of the 4 virulence genes.
C. jejuni isolated from poultry had all of the virulence genes while none of the toxin encoding genes
cdtA,cdtB andcdtC were found in the pork isolate.
