FIG 2.

Dendrogram of 21 clinical and 12 poultry S. enterica serovar Indiana isolates that were resistant to both ciprofloxacin and cefotaxime, constructed based on PFGE with XbaI on patient samples. The isolate identity, source, pulsotype, year of isolation, antimicrobial resistance profile, ESBL genes, mutations in QRDRs, and PMQR determinants were identified. D in strain names indicates isolates from poultry, and P indicates isolates from patients. DF, Dengfeng; JY, Jiyuan; HB, Hebi; KF, Kaifeng; LH, Luohe; SQ, Shangqiu; ZK, Zhoukou; ZZ, Zhengzhou; NT, an isolate whose plasmid replicon typing was nontypeable.
