Abstract

Trimethoprim-sulfamethoxazole (TMP-SMX) or trimethoprim (TMP) alone was given on a random double-blind basis to 26 young women to treat urinary tract infections. Fecal and introital aerobic bacterial floras were identified at 1, 7, 14, and 42 days to analyze changes in these floras or development of resistance to TMP or TM-SMX. Neither TMP alone nor the TMP-SMX combination administered for 2 weeks selected a resistant fecal or introital flora. In the few individuals who had strains resistant to TMP or TMP-SMX before initiation of therapy, these organisms did not persist once therapy began. Both programs effectively cleared the introitus and rectal areas of Enterobacteriaceae. Concentrations of TMP adequate to inhibit the majority of Escherichia coli strains causing urinary tract infections were found in the vaginal secretions.

摘要

将甲氧苄啶-磺胺甲恶唑(TMP-SMX)或单独的甲氧苄啶(TMP)以随机双盲的方式给予26名年轻女性以治疗尿路感染。在第1、7、14和42天对粪便和阴道需氧菌菌群进行鉴定,以分析这些菌群的变化或对TMP或TMP-SMX耐药性的发展。单独使用TMP或TMP-SMX联合用药2周均未筛选出耐药的粪便或阴道菌群。在治疗开始前少数对TMP或TMP-SMX耐药菌株的个体中,一旦开始治疗,这些微生物就不再持续存在。两种方案均有效地清除了泌尿生殖道和直肠区域的肠杆菌科细菌。在阴道分泌物中发现了足以抑制大多数引起尿路感染的大肠杆菌菌株的TMP浓度。
