The aim of this study was to investigate the antibiotic resistance and identification of strains producing broad-spectrum beta-lactamases salmonella strains. The 70 different strains of salmonella were studied that gentamicin, ciprofloxacin, ofloxacin, imipenem, and enrofloxacin were susceptible. The highest resistance to cephalexin (96 %), cefazolin (96 %), cephalothin (65 %), and 69 isolates (98 %), were resistant to more than one antibiotic. The results of the Polymerase Chain Reaction (PCR) were evaluated on ESBL producing isolates using specific primers; in order to investigate the presence of CTX-Mbla, SHVbla, TEMbla and OXAbla, so the presence of germ cell resistance genes in total indicated that 32 isolates (56 %), at least one of the above genes.
