[Intestinal helminths in the DDR district of Rostock].

The population of a rural municipality in the district of Rostock including the staff members of a research institute at that place, who daily go there from a nearby city, were examined helminthologically (as a whole 910 persons). 1.5% of these persons were affected by helminths. Comparative examinations with 407 animal breeders of other municipalities showed the same results (also 1.5%). The examination of seamen going to the trophics (1471 persons) showed other results: 3% were attacked. Foreigners from the tropics staying in the district of Rostock during the same period of time (426 persons) were affected far more: 88%.
