ABSTRACT

The present study was aimed to assess the overall prevalence of MDR and ESBLs from meat samples in Namakkal. A total of 10 (chicken, n=4, goat, n=3 and fish, n= 3) meat samples were studied in which 23 bacteria were isolated. Species of Gram - negative and positive - bacteria were identified as E.coli (22%), P. aeruginosa (9%), K. pneumonia (26%) Salmonella spp. (13%), Proteus spp. (9%), and E.faecalis (22%). The prevalence of MDR isolates was found to be 48%, and a hundred percentage of resistance was against penicillin and lowest resistance to Cefpodoxime. The phenotypic method detected 48% of isolates as presumptive betalactamase producers, however, 39.1% of were as ESBL producers which were by DDST, while using molecular methods detected 55.5%, 78%, 22.2% and 22.2% prevalence of blaSHV, blaTEM, blaCTX-M, and blaOXA respectively. Among the ESBL isolates, 82% were MDR isolates. This showed a wide range of antibiotic - resistant bacteria is prevalent in various meat samples.
