THE CASE OF DERMATITIS IN THE HUMAN AS A RESULT OF THE INFLUENCE OF THE CERCARIA OF THE BIRD SCHISTOSOME

There are numerous cases of dermatitis described world-wide and resulting from the influence of the furcocercaria of the bird schistosome. The host snail species of the schistosome, producing thousands of furcocercaria are common in our country. But, because of too general symptoms of dermatitis resulting from the influence of the schistosome of the larvae, there are many unrecognisable cases. The reaction described was typical of a twenty-seven-year-old man collecting snails in the Piechota Bay in Gostynin (the Province of Kuyavia and Pomerania). In that reservoir, individuals of Lymnaea stagnalis were found, which were infected with sporocysts and furcocercaria of Trichobilharzia ocellata. In the laboratory conditions, a high expulsion of cercaria was observed, which amounted to over 8000 larvae per snail

THE STUDIES OF THE INVASION OF AŁAR/IA ALATA (GOEZE,1782) IN THE PROVINCE OF KUYAVIA AND POMERANIA

The studies were conducted between 1999 and 2001 in two hunting regions. Larval alariosis was revealed in the boars only in one of the studied regions. In this region, the results of the parasitological studies, conducted towards A.alata in the direct host (domestic dogs) and indirect hosts (snails: Planorbis planorbis and Anisus vortex as well as frogs: Rana temporaria and Rana terrestris) were also positive. The lack of the host snails A.alata in the other region might have resulted from no presence of the parasite in the boar

Inwazja Dermanyssus gallinae [DE GEER, 1778] w fermach drobiu w rejonie Torunia

The studies were conducted in three big fully automaticised egg-laying farms within the boundaries of Toruń Voivodship, where Dermanyssus gallinae (DE GEER 1778) was present. The increased invasion of the parasite on one of the farms resulted in the presence of all clinical symptoms of dennanyssosis. A considerable decrease in the body weight, anaemia and organism exhaustion were observed. A growth in the hens' death rate from 1% (when they were not contaminated) to 4% was observed. There was also a decrease in egg-laying, particularly in its top phase. When breeding farms are not contaminated, egg-laying amounts nonnally to 91-93%, whereas in the contaminated farm the percentage lowered to 80-82%. The hens' death rate, a decrease in the egg production as well as a fall in the productive cycle by two months resulted in economical losses suffered by the farm owner. Having excluded the treatment costs, the sum amounted to c. 36,000 PLN in a single production cycle. To fight the parasite effectively, cleansing frequency, desinfecting with Wirkon and Pollena Jod K or caustic soda, and disinsectization with Neguvon and Alfasep 10WP were increased
