We identified 20 to 22 resistance genes, carried in four incompatibility groups of plasmids, in each of five genetically closely related Salmonella enterica serovar Typhimurium strains recovered from humans, pigs, and chickens. The genes conferred resistance to aminoglycosides, chloramphenicol, sulfonamides, trimethoprim, tetracycline, fluoroquinolones, extended-spectrum cephalosporins and cefoxitin, and azithromycin. This study demonstrates the transmission of multidrug-resistant Salmonella strains among humans and food animals and may be the first identification of mphA in azithromycin-resistant Salmonella strains in Taiwan.
