ABSTRACT
To study the transmission of Salmonella and resistance genes,116 Salmonella isolates were tested the sero types,antimicrobial susceptibility,resistant genes on SG1 including β-1actamase genes,and multilocus sequence typing (MLST).Results showed that Salmonella isolates from the chicken belonged to ST11 clone,S.enteritidis,and ST17 clone,S.indiana,and from the pig belonged to ST40,S.derby mostly.ST11 clone showed multidrug-resistant (MDR),resistance to ampicillin,nalidixic acid,tetracycline,and cefoperazone,mostly.ST17 clone showed resistance to nine or more kinds of antibiotics including cephalosporins and fluouoquinolones,a super-MDR clone.ST11 clone carried bla TEM-l-like highly,whereas blaOXA-1-like,blaCTX-M,blaTEM-1-like,and floR,aadA2,sul1,and aac (6')-1b were highly carried in ST17 clone,a new super-MDR clone.The antibiotic abuse and misuse in food supply chains were the main origin of MDR and super-MDR Salmonella,which were transmitted by the chains.It is significance that the control of substance abuse,especially cephalosporins and fluouoquinolones,in food supply chains.
