In the Białowieża Forest the parasitological autopsy of large intestine of 6 bisons was made at the beginning of winter of 1987-1988, and 9 dissections were made in the latter part of both seasons. Four species of nematodes were found to occur together: Chabertia ovina, Oesophagostomum radiatum, Oe. venulosum and Trichocephalus ovis. At the end of wintering in bisons the invasion of Ch. ovina appeared in high percent of animals, but the intensity of it was low. However the extensity and intensity of invasion of three remaining species of nematodes distinctly arose. In comparison with bisons in closed reserves, free living bisons assimilated Oe. venulosum and Ch. ovina. It is likely that the winter quarters are the source of invasion. It can be explained by the permanent accumulation of feaces with invasive forms of nematodes, and by feeding bisons on the great amount of hay, in which the invasive forms of nematodes may also occur.

Relationship between faecal egg counts and haematological parameters: PCVs, peripheral eosinophil counts, total white blood cell counts (TWBCs) and white cells composition in blood of Polish Wrzosówka breed of sheep were estimated in 1995 and 1996. Hoggets were naturally infected with gastrointestinal nematodes. Anthelmintics were not used. Among Teladorsagia circumcincta, Cooperia spp., Chabertia ovina, Nematodirus spp. (mainly N. spathiger) two species: Trichostrongylus spp. and Haemonchus contortus dominated. High repeatability of EPGs, PVCs and peripheral eosinophil counts were observed over two grazing seasons. There were no significant changes in TWBCs, in percentage of lymphocytes and neutrophils in blood smears. Marked differences in percentage of eosinophils in blood smears were confirmed in peripheral eosinophil counts. Additionally, the eosinophil counts in most sampling data correlated negatively with EPGs. The lowest level of haematocrit correlated negatively with EPGs when the highest percentage of L3 H. contortus larvae were found in the faecal culture. The results reveal that EPGs, PVCs and peripheral eosinophil counts could be considered in terms of phenotypic markers for identification of Wrzosówka sheep with different level of acquired immunity to natural trichostrongylid infection.
