[Contributions to the parasitic fauna of the GDR. 4. Studies of the presence of helminths in the brown rat (Rattus norvegicus)].

120 Brown rats (Rattus norvegicus), caught in a territory with animal production buildings in GDR, were infected with Ganguleterakis spumosa (58,3%), Hymenelopesis diminuta (44,1%) and Hydatigera taeniaeformis larv. (3,3%). The parasitological findings were compared with those of other authors from the neighbouring countries like CSSR, Poland, FRG and the former Deutsches Reich. For faunistic information results are necessary of researches in different parts of the country.
