Abstract: Campylobacter spp. are significant zoonotic pathogens, increasingly recognized for their role in the transmission of antimicrobial resistance (AMR) between animals and humans. This study aims to determine the occurrence, antimicrobial resistance profiles, and characterization of multidrug resistance indices of Campylobacter spp. isolated from domestic pets in Kelantan, Malaysia. Methods: Rectal swabs (n = 150) were collected from both healthy and diarrheic cats. Campylobacter spp. were isolated and confirmed by PCR, and antimicrobial susceptibility was assessed using the disk diffusion method. Results: Campylobacter spp. were detected in 35.3% of cats (53/150; SE = 0.04; 95% CI: 28.1–43.3%), with C. upsaliensis identified as the predominant species (33.3%; SE = 0.05; 95% CI: 24.5–43.6%), followed by C. jejuni (17.8%; SE = 0.04; 95% CI: 11.3–26.9%) and C. coli (7.8%; SE = 0.03; 95% CI: 3.8–15.2%). Isolates exhibited high resistance rates to amoxicillin (90.6%), ampicillin (81.1%), tetracycline (67.9%), erythromycin (62.3%), and sulphonamides (54.7%). Conclusion: The study reveals a substantial prevalence of Campylobacter spp. and notable levels of antimicrobial resistance among feline isolates, highlighting the zoonotic threat in Malaysia. These findings emphasize the importance of integrated surveillance and prudent antimicrobial stewardship under a One Health framework.
