Most of these studies were performed early in the antimicrobial era , with nitrofurantoin and sulfonamides being the most common antimicrobials 在抗生素应用的早期，进行了许多治疗尿路感染的研究，呋喃妥英和磺胺类药物是最广泛应用的治疗尿路感染的抗生素。

3 . nitrofurantoin resistance remained low amongst most of the urinary pathogens , with the exception of proteus spp . , which are inherently resistant to nitrofurantoin 3 .除了变形杆菌种具先天的喃妥因抗药性之外，大部份泌尿道病原体对喃妥因抗药性都维持低水平。

Of the isolates tested , the percentage of strains resistant to nitrofurantoin was not applicable according to the national committee for clinical laboratory standards or not performed 没有对喃妥因的抗药性进行测试或根据美国national committee for clinical laboratory ，对喃妥因的抗药性测试是不适用的。

A prospectie , randomized study of continuous antimicrobial therapy to the end of pregnancy compared with 14 days of nitrofurantoin or sulfamethizole , followed by weekly urine culture screening and re - treatment if bacteriuria recurred , reported similar outcomes for the 2 treatment groups [ 65 ] 一个前瞻性随机研究发现：持续应用抗生素治疗到孕期末与应用呋喃妥因或磺胺类药物治疗14天，随后，通过每周尿培养筛选，假如菌尿复发就再用药治疗的结果相同。
