Materials and Methods: The presence of ESBL in 12 Salmonella isolates (6 Salmonella typhimurium, 3 Salmonela enterica spp., 2 Salmonela enterica subspp salamae and 1 Salmonela enterica sub. spp. diarizonae) was determined using phenotypic (combined disc method) method and genotypic methods by targeting EBSL genes.

Results: Out of 12 Salmonella isolates, five isolates were confirmed as ESBL producers by both phenotypic and genotypic methods of which all are Typhimurium serotypes.

Conclusion: The current study showed that only Typhimurium isolates were able to produce extended spectrum beta-lactamase which is an important pathogenic bacterium in birds and livestock and can acts as a health hazard to humans as it will help in developing antibiotic resistance, thereby reducing the efficiency of the treatment.
