[The importance of flies (Diptera-Brachycera) in the dissemination of helminth eggs from sewage treatment plants].
Screenings were carried out in four mechanico-biological municipal wastewater treatment plants in two climatico-geographic regions of Slovakia (submontane region: Levoca, Poprad and Tatranská Lomnica, lowland region: Michalovce). Ovoscopical studies traced the occurrence of helminth eggs in stabilized sludges in sludge beds. The flies (Diptera-Brachycera) are considered as potential biological vectors of helminth eggs. The stabilized sludges in sludge beds showed the presence of a wide range of helminth eggs Ascaris sp. 0-184 spec. Hymenolepis sp. 0-5 spec. Toxocara sp. 0-17 spec. Taenia sp. 0-2 spec. Trichuris sp. 0-17 spec. a Capillaria sp. 0-4 spec./100 g of sample dry matter. In the areas of four sewage treatment plants 461 fly specimens (358 females, 103 males) were captured, belonging to 31 species. On three specimens of Protophormia terraenovae ectoparasites (mites) were detected. No eggs were found on the body surface of the flies.
