[The intestinal parasite fauna in patients, returned from the tropics, from the Dresden district].

It is reported on the affection with intestinal parasites in 438 persons who returned from the tropics. In these test persons were also established only those species of parasites which were proved in the Dresden inhabitants. However, there were remarkable quantitative differences between the affection of the persons returning from the tropics and the Dresden inhabitants. Thus by laboratory examinations in Dresden in the persons returning from the tropics were established infections with Entamoeba histolytica (7.0%), with Dientamoeba fragilis (17.9%), with Lamblia intestinalis (9.0%) as well as with Trichuris trichiura (3.4%), where as the extensity of affection with the corresponding parasites is for the Dresden inhabitants 1.9%, 4.7%, 5.0%, and 1.6%. It is referred to the fact that all persons who returned from the tropics should parasitologically be examined for an infection with Entamoeba histolytica.
