Abstract
The present study aimed to determine the
pathogenic Escherichia coli and Salmonella spp. and to investigate
their phylogenetic relation by Enterobacterial Repetitive Intergenic Consensus
Polymerase Chain Reaction (ERIC-PCR) in retail chicken samples. A total of 75
samples were processed for isolation of E. coli and Salmonella
spp. by classical cultural methods and isolates were confirmed by the
species-specific PCR. Salmonella spp. was detected in 21.3% and E.
coli was detected in 74.6% of the chicken carcasses. S. Enteritidis
and S. Typhimurium were not detected in chickens by duplex PCR-based
assay. O157 based on serotyping and PCR, was not detected in any of the
isolates. Besides, virulence and toxin genes were not detected in any of the
E. coli isolates. According to ERIC patterns, the obtained ribotypes showed
that all Salmonella spp. isolates presented large genetic diversity,
whereas only two (3.5%) of E. coli isolates were genetically identical.
Although virulent E. coli, and pathogenic serotypes of Salmonella
spp. were not detected in our study, it is thought that their high incidence
should be considered as an indicator of failure to comply with hygienic
conditions and lack of sanitary practices especially in slaughterhouses.
