A total of 63 Salmonella isolates(19 from chickens, 3 from ducks, 2 from turkeys, 2 from quails and 2 from pigeons) were examined inthis study for their wide spread resistance against different antimicrobial agents. The antimicrobialsusceptibility was applied on all isolates then PCR was applied for all resistant isolates to detect theresistance genes of different antimicrobial agents (qepA, qnrS, aac (6') - ib-cr) for quinolone resistantisolates, bla Tem for β lactam resistant isolates, sul1 for Sulfonamide resistant isolates, floR forFlorphenicol resistant isolates, aadA2 for Streptomycin resistant isolates and tetA (A) forOxytetracycline resistant isolates, in addition to gyrase enzyme gene (gyrA). DNA sequencing was donefor three selected isolates to detect possible mutations in the quinolone-resistance determining regionsof the gyrA gene}, keywords = {Salmonella,resistance genes,Poultry}, url = {https://bvmj.journals.ekb.eg/article_32499.html}, eprint = {https://bvmj.journals.ekb.eg/article_32499_a0e7976a77dac9188c4a01e234db2fcd.pdf} }
