产毒索性大肠杆菌(ETEC)是旅行者腹泻的最常见病因,但是这种疾病可由许多因素引起,包括其它细菌、病毒和寄生虫.在20～40%的病例中病因学仍未清楚.本文作者对摩洛哥的一个普通旅游点在寒冷及温暖季节的旅行者腹泻病因学的潜在差别进行了研究.此项研究是在从芬兰到摩洛哥阿加迪尔的成人旅游者中进行的.研究间期为1989年1月11日～2月8日(冬季)和10月24日～11月21日(秋季).在第一组(冬季),470名自愿参加研究的旅游者中有204名
Toxigenic E. coli (ETEC) is the most common cause of traveler’s diarrhea, but the disease can be caused by many factors, including other bacteria, viruses and parasites, and the etiology remains unclear in 20-40% of cases. The authors studied the potential differences in etiology of traveler’s diarrhea during a cold and warm season at an ordinary tourist spot in Morocco, from an adult traveler from Finland to Agadir, Morocco. The study period January 11 to February 8, 1989 (winter) and October 24 to November 21 (fall) in 1989. Of the 470 volunteers who participated in the study in the first group (winter), 204
