Thirty-two asymptomatic travellers who had recently journeyed in the Near, Middle, and Far East and had experienced a high incidence of diarrhoeal disease were screened for heat-labile enterotoxigenic Escherichia coli (ent+ E. coli) and other bacterial and parasitic pathogens. Six percent were colonized with ent+ E. coli and while other bacterial pathogens were not found, the intestinal protozoa Giardia lamblia (13%), Entamoeba histolytica (6%), Entamoeba coli (6%), Endolimax nana (6%), and Entamoeba hartmanni (3%) were detected in the stools. Ent+ E. coli, G. lamblia and E. histolytica should be considered in the differential diagnosis of gastrointestinal disease in travellers returning from the Orient. Furthermore, these travellers may be a potential source for the introduction of ent+ E. coli into communities where such organisms are relatively rare.
对32名近期前往近东、中东和远东地区旅行且腹泻疾病发病率较高的无症状旅行者进行了不耐热肠毒素大肠杆菌（肠毒素+大肠杆菌）以及其他细菌和寄生虫病原体的筛查。6%的人感染了肠毒素+大肠杆菌，未发现其他细菌病原体，但在粪便中检测到肠道原生动物蓝氏贾第鞭毛虫（13%）、溶组织内阿米巴（6%）、结肠内阿米巴（6%）、微小内蜒阿米巴（6%）和哈氏内阿米巴（3%）。对于从东方归来的旅行者，在胃肠道疾病的鉴别诊断中应考虑肠毒素+大肠杆菌、蓝氏贾第鞭毛虫和溶组织内阿米巴。此外，这些旅行者可能是将肠毒素+大肠杆菌引入此类生物体相对罕见社区的潜在源头。
