A severe epidemic of dysentery began late in 1979 in northeast Zaire and spread to Rwanda, Burundi, and Tanzania. The epidemic strain is a multiply resistant Shigella dysenteriae type 1, which acquired resistance against trimethoprim and more recently against nalidixic acid in the course of the epidemic. A comparative open trial in Rwandan adults with Shiga dysentery involved 18 patients treated with norfloxacin at 400 mg twice daily and 12 patients treated with nalidixic acid at 1 g three times daily for 5 days. All isolates showed in vitro susceptibility to both drugs. Though norfloxacin eliminated Shigella organisms from stools more rapidly than nalidixic acid, its clinical superiority did not reach the level of significance. Norfloxacin is a promising drug and is more effective than nalidixic acid in the treatment of multiresistant shigellosis.
1979年末,扎伊尔东北部暴发了严重的痢疾疫情,并蔓延至卢旺达、布隆迪和坦桑尼亚。流行菌株为多重耐药的1型志贺氏痢疾杆菌,在疫情期间获得了对甲氧苄啶的耐药性,最近又对萘啶酸产生了耐药性。在卢旺达成年人中进行的一项关于志贺氏痢疾的比较开放性试验,18名患者每日两次服用400毫克诺氟沙星,12名患者每日三次服用1克萘啶酸,疗程均为5天。所有分离株在体外对两种药物均敏感。虽然诺氟沙星比萘啶酸更快地从粪便中清除志贺氏菌,但它的临床优势未达到显著水平。诺氟沙星是一种有前景的药物,在治疗多重耐药性志贺氏菌病方面比萘啶酸更有效。
