From: Characterization of Shiga toxin-producing Escherichia coli isolated from healthy pigs in China
Dendrogram of PFGE profiles of 88 STEC isolates from pigs in farms and slaughter houses. The 6 PFGE clusters were marked on the node as A to F. Non-typeable with available O antisera was marked ONT and non-motile isolates were labeled with the H types in square brackets. Displayed on the right hand side are strain name, sample name, serotype, hemolysis, sorbitol fermentation (SOR), sequence type (ST) and antibiotic resistance. Abbreviations for antibiotics are: AMP, Ampicillin; PIP, Piperacillin; AMC, Amoxicillin-clavulanic acid; SAM, Ampicillin-sulbactam; FEP, Cefepime; CTX, Cefotaxime; CRO, Ceftriaxone; KF, Cephalothin; CXM, Cefuroxime; ATM, Aztreonam; IPM, Imipenem; MEM, Meropenem; GM, Gentamicin; K, Kanamycin; S, Streptomycin; TE, Tetracycline; CIP, Ciprofloxacin; NOR, Norfloxacin; LVX, Levofloxacin; NA, Nalidixic acid; SXT, Trimethoprim-sulfamethoxazole; C, Chloramphenicol; F, Nitrofurantoin. Place of isolates were contained in the first letter of strain names: B means Beijing city, C means Chongqing city and G means Guizhou province.
