This study determined the phenotypic characteristics of Campylobacter from ruminants slaughtered in two major abattoirs in Ilorin metropolis of Kwara state, Nigeria. In total, 350 fecal samples were collected from beef cattle (n = 200) and goat (n = 150). Campylo-bacter was isolated and phenotypically characterized using standard bacteriological methods. Seventy (20%) of the samples were positive for Campylobacter. The isolation rate of Campylobacter from female animals (11.71%) was higher than that of males (8.28%), albeit there was no significant difference (P > 0.05). Similarly, the rate of isolation of Campylobacter from bovine (12.86%) was not statistically significant (P > 0.05) from that of caprine (7.14%) species. Only five (7.14%) of the total isolates were Campylobacter jejuni. All isolates were resistant to nalidixic acid and pan-susceptible to gentamicin, but there were different rates of antimicrobial resistance to other tested antibiotics. There was also high rate of resistance to cefotaxime (83%) and ampicillin (76%), and 53% of the isolates displayed multidrug resistance phenotypes. The study established 20% Campylobacter contamination of ruminants slaughtered in the two major abattoirs in Ilorin, and most of the isolates were multidrug resistant. Further study is recommended to molecularly characterize the species of Campylobacter circulating in the study area.
