a beteg szervezetét, gyengítik a természetes ellenállóerejét és bizonyos esetekben csökkentik a munkaképességét is fizikai és szellemi téren egyaránt. A humán parazitózisok okozta károk mértékét pénzben nem tudjuk kifejezni. Nem ismeretes, hogy a betegállományban levők munkakieséséből hány forint kár éri a népgazdaságot, mennyibe kerül a betegek egészségügyi ellátása stb. A szerző a parazitózisok közegészségügyi és állategészségügyi fontossága miatt javasolja, hogy az MPT tűzze napirendre a parazitológia ökonómiai problémáinak megtárgyalását. Az Elnökség alakítson bizottságot mind a humán-, mind a veteriner-parazitózisokra vonatkozóan, azzal a feladattal, hogy pontosan felmérjék a parazitózisok kártételét Magyarországon. According to statistical data, losses caused by various animal diseases, deaths, and emergency slaughtering, amount to 15-20 per cent, on average, of the total annual value of animal products in economically developed countries. A significant quota of losses due to animal diseases is attributable to parasitoses. Calculation of the exact ratio between infectious and parasitic diseases is difficult, yet, according to available data, about one-third of the total loss due to animal disease is caused by parasitic infections. Due to parasitic diseases, the Hungarian economy suffers an annual loss of about 800 million Porints (10 million pounds). The heaviest loss is caused by liver-fluke disease of cattle and sheep amounting to about 400 million and 30 million Pt, respectively ,per year. Pig ascaridosis causes losses amounting to 100 million Pt yearly ,poultry ascaridosis to about 240 million Pt, pig echinococcosis to 20 million Pt, the .stomach and gut helminthoses of sheep to 20 million Pt, the lung helminthoses of sheep and cattle to about 15 million Pt. Significant losses are also brought about by coccidiosis of chicken,calves, and rabbits, babesiosis and bunostomosis of cattle ,monieziosis and coenurosis of sheep, and several ectoparasito3es. Determination of the economic importance of human parasitoses is even more difficult. According to the results of laboratory investigations, about one fifth of the inhabitants of Hungary are infected by various kinds of parasitic protozoa,helminths , and arthropods. Most human parasitoses are not acute and
