Abstract

Foodborne infections with antimicrobial-resistant Campylobacter spp. remain an important public health concern. Publicly available data collected by the National Antimicrobial Resistance Monitoring System for Enteric Bacteria (NARMS) related to antimicrobial resistance in Campylobacter spp. isolated from broiler chickens and turkeys at the slaughterhouse level across the United States of America between 2013 and 2021 was analyzed. A total of 1,899 chicken - (1,031 C. coli and 868 C. jejuni) and 798 turkey (673 C. coli and 123 C. jejuni) - origin isolates were assessed. Chicken isolates exhibited high resistance to tetracycline (43.65%), moderate resistance to ciprofloxacin (19.5%), and low resistance to clindamycin (4.32%) and azithromycin (3.84%). Turkey isolates exhibited very high resistance to tetracycline (69%) and high resistance to ciprofloxacin (39%). The probability of resistance to all tested antimicrobials, except for tetracycline, significantly decreased during the later part of the study period. Turkey-origin Campylobacter isolates had higher odds of resistance to all antimicrobials than isolates from chickens. Compared to C. jejuni, C. coli isolates had higher odds of resistance to all antimicrobials, except for ciprofloxacin. The study findings emphasize the need for poultry-type-specific strategies to address differences in antimicrobial resistance among Campylobacter isolates.
