Major Campylobacter jejuni in chicken carcasses are more multidrugresistant to different antibiotics than the standard strain.

Chickens are major reservoirs for Campylobacter jejuni . In this study, we assessed the multidrug resistance (MDR) of C. jejuni found in chicken carcass obtained from different companies in Riyadh city, Saudi Arabia and compared it with that of the standard strain of C. jejuni , ATCC 22931. Of the 30 strains tested, C. jejuni subsp doylei H1 exhibited the highest resistance to the tested antibiotics, with a ratio of resistance of 92.86%. Moderate resistance to antibiotics (ratio of resistance, 50%) was noticed for C. jejuni 2 A2, C. jejuni 1 B2, and C. jejuni 2 I1. The lowest resistance to antibiotics was exhibited by C. jejuni subsp doylei J1, with a ratio of resistance of 7.14%. The main cause of high variation in ratios of resistance among the Campylobacter strains may be due to the overuse of antibiotics, especially by poultry breeders or farmers. Transmission of Campylobacter spp . via chicken carcass contributes to the emergence of antimicrobial resistance in C.jejuni , which in turn poses public health risk.
