  Campylobacter is the primary bacterial cause of human intestinal infections worldwide. Species identification of fifty one Campylobacter positive isolates collected at two slaughterhouses in Lebanon was done using the 16 S rRNA sequencing. Antimicrobial susceptibility testing (AST) was performed using a wide range of β lactam agents and tetracycline. Polymerase chain reactions (PCR) detection of the blaOXA-61 and tet (O) genes in resistant and susceptible isolates to ampicillin and tetracycline respectively was deter - mined. Genomic diversity of the isolates was assessed using Random Amplified Polymorphic DNA (RAPD). Sequencing analysis re - vealed that all tested isolates were Campylobacter coli . AST showed resistance in the isolates to cephalothin and aztreonam (100%), cefamandole and cefoxitin (98%), tetracycline (94%), ampicillin (49%), amoxicillin (47%), piperacillin (45%), carbenicillin (37%), ticarcillin (20%), ceftazidime (18%), cefotaxime (8%) and amoxicillin-clavulanic acid (2%). All ampicillin-resistant isolates and 84% of the ampicillin-sensitive ones carried the blaOXA-61 gene. All tetracycline-resistant isolates were positive for the tet (O) gene with 98% encoded on plasmids. RAPD analysis revealed nine distinct clusters with a minimum percentage of 43.5% genomic similarity. This study emphasizes the importance of surveillance in identifying and controlling commonly circulating food borne pathogens.
