Characteristics of ESBL-producing <i>E</i>. <i>coli</i> isolates from wastewater chains.

* Am = ampicillin Cx = cefotaxime Cz = ceftazidime Te = tetracyclin St = streptomycin Ci = ciprofloxacine Na = nalidixic acid Su = sulfamethoxazole Tr = trimethoprim Ch = chloramphenicol. MICs were determined with Etests (Cz, Na, Su, Ch) and microbroth dilution (remainder of antimicrobials), resistance defined as MIC greater than or equal to the epidemiological cut-off (EUCAST). Indicated in bold are pheno-/genotypes present in HCI and municipal wastewater. Characteristics of ESBL-producing E. coli isolates from wastewater chains.
