Escherichia coli (E. coli) is a commensal organism in humans and animals. It can serve as a reservoir for antibiotic resistance, thus providing an indicator of drug resistance patterns in a community. We investigated antibiotic resistance in E. coli isolated from nondiarrheal stool samples of 6-month-old infants (n = 110) from northwest Bangladesh. We conducted susceptibility testing using a disc diffusion assay against 20 antibiotics. Resistance was most pronounced for macrolides (98.2% resistant), whereas the most sensitive antibiotics were fosfomycin (100%), gentamicin (99.1%), meropenem (98.2%), mecillinam (97.3%), tigecycline (97.3%), and imipenem (87.3%). Excluding erythromycin, roughly 55% of isolates were multidrug-resistant. Our results likely reflect the burden of drug-resistant E. coli in the guts of infants in rural Bangladesh and the prevailing drug resistance patterns in this community.
大肠杆菌(E. coli)是人和动物体内的共生生物。它可作为抗生素耐药性的储存库,从而为一个社区的耐药模式提供指标。我们调查了从孟加拉国西北部6个月大婴儿(n = 110)的非腹泻粪便样本中分离出的大肠杆菌的抗生素耐药性。我们使用纸片扩散法对20种抗生素进行了药敏试验。对大环内酯类抗生素的耐药性最为明显(98.2%耐药),而最敏感的抗生素是磷霉素(100%)、庆大霉素(99.1%)、美罗培南(98.2%)、美西林(97.3%)、替加环素(97.3%)和亚胺培南(87.3%)。排除红霉素后,大约55%的分离株对多种药物耐药。我们的结果可能反映了孟加拉国农村地区婴儿肠道中耐药大肠杆菌的负担以及该社区普遍存在的耐药模式。
