Fig. 1From: Antimicrobial resistance and prevalence of tetracycline resistance genes in Escherichia coli isolated from lesions of colibacillosis in broiler chickens in Sistan, Irana: Electrophoresis results for detecting the tetA and tetD genes. Lanes: 1, marker; 2, positive control; 3, negative control; 4, isolate contains tetA gene; 5 & 6, isolates contain tetA and tetD genes. b: Electrophoresis results for detecting the tetB and tetC genes. Lanes: 1, marker; 2, positive control; 3, negative control; 4 & 8, isolates contain tetB gene; 6 & 9, isolates contain tetC gene; 5 & 7, isolates contain tetB and tetC genesBack to article page
