A total of 332 samples of animal food origin comprising 104 poultry, 137 fish, 51 pork and 40 goat (chevon) were screened. Molecular typing of Aeromonas isolates revealed that all the 38 isolates belonged to Aeromonas spp. and were positive for 16S rRNA (100%), ahh1 (60.52%), asa1 (42.10%), A. hydrophila aerA (13.15%) and AHCYTOEA/aerA (5.26%). It was noted that aerolysin producing toxin genes were the most prevalent irrespective of their geographical locations and the most common single gene carried among all the isolates examined was ahh 1 (60.52%).
