Abstract
Arcobacter is an emerging foodborne pathogen having zoonotic significance. Enterobacterial repetitive intergenic consensus (ERIC) PCR and repetitive sequence-based PCR (rep-PCR) analysis of a total of 41 Arcobacter isolates revealed a greater degree of genetic diversity. ERIC-PCR genotyping distinguished 14, 13 and 12 genotypes among 16, 13 and 12 isolates of A. butzleri, A. cryaerophilus and A. skirrowii, respectively. Rep-PCR genotyping distinguished 15, 12 and 11 genotypes among 16, 13 and 12 isolates of A. butzleri, A. cryaerophilus and A. skirrowii, respectively. The discriminatory power for ERIC and rep-PCR was found to be 0.997 and 0.996, respectively. Close clustering between isolates of animal and human origin are indicative of probable zoonotic significance.
