Heat labile entero toxigenic escherichia coli and intestinal protozoa in asymptomatic travelers



Heat labile entero toxigenic escherichia coli and intestinal protozoa in asymptomatic travelers



Southeast Asian Journal of Tropical Medicine and Public Health 8(4): 476-479



Thirty-two asymptomatic travellers who recently journeyed in the Near, Middle, and Far East and experienced a high incidence of diarrheal disease were screened for heat-labile enterotoxigenic (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. These travellers may be a potential source for the introduction of ent+ E. coli into communities where such organisms are relatively rare.
