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.

Qualities of microscopical pictures of digenean larvae total slides stained with different acetocarmines were compared. Semichon's acidifying carmine for topographical staining. Schneider's and Belling's carmines for chromosomes as well as iron acetocarmine (modification of the last two) were used. The last stain permits to obtain the slides, that in respect of their colour and quality of microscopical picture may be compared with slides stained with Semichon's carmine. Contrast, colour and reaction of staining depend on concentration of iron acetate in the staining solution. Total slides of investigated larvae stained respectively with Schneider's and Belling's carmines are not enough readable.

To supply more documentary evidence for the effect of parasitic infection on activity of neurosecretory centres in the cerebral ganglia of the snail host, caudo-dorsal and light green cells of adult individuals of Lymnaea stagnalis naturally infected with digenean parthenites were subjected to karyometric analysis. In infected animals significant enlargement of nuclear volumes of both examined types of neurosecretory cells was ascertained. Mean nuclear volume of the light green cells in snails infected with Furcocercariae was significantly lower in comparison with the individuals infected with parthenites from groups Echinostomata and Xiphidiocercariae. In remaining cases differences in nuclear volumes among subpopulations distinguished on the ground of an infection factor were not statistically significant.

Total protein and activities of: alpha-amylase, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase in haemolymph of the freshwater snail Lymnaea stagnalis, naturally infected with digenean larvae were investigated. There were no any changes in these parameters in the snails infected with Cercaria tenuispina that occupies mainly haemocoel sinuses. Significant increase of activities of all examined enzymes in haemolymph of the snails infected with larvae belonging to the Furcocercariae group was ascertained. These changes were proportional to the degree of injury of the digestive gland, examined with the use of the thymol turbidity test. Total protein level was significantly higher only in haemolymph of snails with higher values of this test.
