A total of 200 fish samples were examined for the presence of extended spectrum β-lactamases (ESBL) producing Aeromonas spp. in raw fish samples collected from retail markets of Durg, Raipur, Rajnandgaon and Balod districts of Chhattisgarh state. A total of 70 (35%) fish samples were found contaminated with Aeromonas spp. Among 70 Aeromonas isolates, 16 (22.9%) were phenotypically identified as ESBL producer. Out of these 16 isolates, 11 and 5 were from fresh water and marine fish samples, respectively. Further antimicrobial sensitivity testing revealed that the isolates were resistance for ampicillin (88.6%), cephalexin (64.3%) followed by oxytetracycline (48.6%). Among 62 ampicillin resistant isolates, 39 isolates were recovered from fresh water fish samples and 23 from marine water fish samples. Multiple antibiotic resistant (MAR) index for Aeromonas isolates varied between 0.11 and 0.88. The study indicates the presence of multidrug resistant ESBL producing Aeromonas spp. in fish samples.
