^aMLST, multilocus sequence type; CIP, ciprofloxacin; CST, colistin; CTX, cefotaxime; GEN, gentamicin; MEM, meropenem; SAM, ampicillin-sulbactam; SXT, trimethoprim-sulfamethoxazole; TIM, ticarcillin-clavulanate; TEL, tellurite (nonantibiotic compound); TET, tetracycline. Classification of antibiotic resistance was done according to breakpoints published by the Clinical and Laboratory Standards Institute and is indicated as follows: susceptible, underlining; intermediate, italics; resistant, boldface (46). *, values for the components are separated by a slash.
