Background Due to their potential to carry a wide range of bacteria, pigeon feces may contribute to the spreading of infectious diseases in urban settings. Objective This study analyzed the presence of enteric bacteria from pigeon feces in Jeddah and their antimicrobial susceptibility and described the molecular characteristics of the carbapenem resistance genes it produced. Method Two hundred twenty-five pigeon feces specimens were collected from eight parks in Jeddah. Conventional microbiology techniques were employed to identify the isolated bacteria, and the automated Vitek2® system (bioMérieux, Marcy-l'Étoile, Lyon, France) provided additional confirmation. Kirby-Bauer disk diffusion method was utilized to screen for antimicrobial resistance. Only 50 antibiotic-resistance isolates further underwent molecular diagnosis for testing groups of carbapenems-encoding genes (blaNDM, blaSIM, and blaAIM), using multiplex polymerase chain reaction (PCR). Result Of the 50 antibiotic-resistant isolates, 28% (14/50) were Klebsiella pneumoniae, 24% (12/50) were Enterobacter cloacae, and 48% (24/50) were Escherichia coli. Ninety percent (90%) of the isolates showed resistance to cefuroxime, 56% to gentamicin, 52% to amoxicillin/clavulanic acid, and 100% to meropenem. NDM beta-lactamase was the most often discovered gene (26%) and was followed by AIM beta-lactamase (5%) Conclusion According to this study, there may be a chance for resistant K. pneumoniae, E. cloacae, and E. coli to spread amongst several hosts within the same area. Consequently, to prevent the continued occurrence and dissemination of resistant strains among other hosts in the same location, it is essential to monitor the AMR (antimicrobial resistance) of E. coli, E. cloacae, and K. pneumoniae from pigeons.
