Abstract

The aim of this study was to evaluate antimicrobial susceptibility of ESBL-producing E. coli isolated from healthy residents of Nguyen Xa, Vu Thu, Thai Binh province. One hundred and sixty three E. coli isolates were examined for ESBL phenotype. Isolates with ESBL phenotype (n=135) were then evaluated for antimicrobial susceptibility to 12 antibiotics by disk diffusion method (CLSI, 2013). Antimicrobial susceptibility test results showed that ESBL-producing E. coli isolates were resistant to ampicillin, cefotaxime, tetracycline, trimethoprim-sulfamethoxazol with very high prevalence (70-100%); to streptomycin, nalidixic acid, chloramphenicol and gentamycin with high prevalence (30-70%); to ciprofloxacin, kanamycin and ceftazidime with lower prevalence of 23.7%, 21.5% and 18.5%, respectively. Only three antibiotics having resistant prevalence lower than 10% were meropanem, fosfomycin and cefoxitin. Classification under Magiorakos’ criteria showed that 87.4% ESBL-producing E. coli isolates were multidrug resistant (non-susceptible to three or more antibiotic catagories). The results indicated that ESBL-producing E. coli isolated from healthy residents of Nguyen Xa commune were resistant to a number of common antibiotics and 87.4% of them were multidrug resistant.
