In our study of nursing home residents with clinically suspected urinary tract infection who did not require the use of an indwelling catheter, we identified bacteria isolated from urine samples, the resistance patterns of these isolated bacteria, and the antibiotic therapy prescribed to the residents. Escherichia coli, the predominant organism isolated, frequently was resistant to commonly prescribed oral antibiotics. Trimethoprim-sulfamethoxazole remains the best empiric antimicrobial therapy for a urinary tract infection, but nitrofurantoin should be considered if E. coli is identified.
在我们对无需留置导尿管的疑似尿路感染的养老院居民的研究中，我们鉴定了从尿样中分离出的细菌、这些分离细菌的耐药模式，以及为居民开出的抗生素治疗方案。最常分离出的病原体是大肠杆菌，它经常对常用的口服抗生素耐药。复方磺胺甲噁唑仍然是尿路感染的最佳经验性抗菌治疗药物，但如果鉴定出大肠杆菌，应考虑使用呋喃妥因。
