Opis:
Protozoa from the genus Eimeria belong to the least recognized parasites of the European bison. There are only a few data concerning the infection of the bison by these protozoa in Białowieża Forest. In the winter of 2007/2008 weighting 3 g fecal samples from the rectum of 16 shot bison were examined by flotation method. In 13 of them were found coccidian oocysts from genus Eimeria, which were determined to the species by morphometric study under the microscope. In all 13 positive samples, it is 81.2%, oocysts of Eimeria bovis were found. Intensiveness of this infection oscillated from 1 to 181 and the mean one was 38 oocysts. E. zuernii was found in 9 samples in the mean intensity 19 (1–154) oocysts. E. ellipsoidalis occurred in 3 bison with a very low intensity 1 to 3 oocysts. The most rarely occurred E. canadiensis, only in 2 examined bison in the number of 2 and 3 oocysts. All found coccidian species are the typical parasites of cattle. Białowieża Forest is a new place of occurrence of these parasites. European bison is a new host for E. zuernii.

Opis:
Background. The aim of these studies was to determine the level of infection of European bison by nematodes belonging to the genus Setaria. Material and methods. From February 2006 to February 2007 21 bisons from 6 months to 20 years old shot in Białowieża Forest have been examined. During the necropsy pleural and peritoneal cavities were macroscopically examined for the presence of nematodes. The parasites were removed from tissues and fixed in 70% ethanol with 5% addition of glycerol and then identified to the species. Samples of blood were taken from shot bison and after centrifugation in microhaematocrit tubes directly examined to confirm the infection. Results. Nematodes Setaria labiatopapillosa were found in 71% of examined bisons. They usually laid freely in peritoneal cavity and sometimes also in pleural one. Accidentally single nematodes were observed in omentum on the surface of omasus and on the surface of liver surrounded by connective tissue. Intensity of bison infection by S. labiatopapillosa varied from 1 up to 24 specimens. Both young and old animals were infected with these nematodes. Observed after 3 years period over 30% rise of prevalence of nematodes S. labiatopapillosa, occurrence of these nematodes in all age groups of this host, and high intensity of infection are alarming. Although these nematodes in their typical localization and low level of infection do not evoke visible symptoms, the pathogenity of this species of nematode is not yet sufficiently recognized, and it is the reason, that monitoring of this infection in bison is necessary

Opis:
Fecal samples from red deer from polish and belorussian parts of Białowieża Forest were examined by Baermann method. First stage larvae of three species of lung nematodes were found. In polish part in 100% of samples were larvae of E. cervi, in 50% V. sagittatus and in 21% D. noemeri, and in belorussian the level of infection was lower and larvae were in 92%, 36% and 12% of samples respectively. In significant part of samples were met mixtured invasion of two or three species. Finding of larvae of E. cervi is the first registration of this species in belorussian part of Białowieża Forest, and V. sagittatus is a new species for the fauna of Byelorussia. Ncmatodes E. cervi are dangerous for domestic ruminants.

Bison bonasus
Opis:
Samples of oesophagus, diaphragm and heart muscles were taken from one European bison from Białowieża Forest during seasonal European bison elimination in 2008. Five gram of each muscle was examined by staining small samples in 0.2% aqueous solution of methylene blue. After that they were placed between compressor glasses and examined under a dissecting microscope in order to detect Sarcocystis sp. infection. All sarcocysts observed were counted. The 5-g sample of the heart muscle yielded a total of 756 sarcocysts while that of the diaphragm contained 107 of them and that of the oesophagus – 89. All of the sarcocysts were isolated from 1 g of each muscle by using preparation needles (probes). After that the sarcocysts were taken to 0.5% physiological solution and examined under light microscope. The special attention was paid to detection of their cyst wall, which was thin (1 mm up to 1.2 mm) and smooth in all cases. Sometimes villar protrusions were seen on the surface of the cysts. Differences between the size of sarcocysts isolated from different muscle samples were observed. The longest and the slenderest sarcocysts were found in the diaphragm. Slightly smaller in the oesophagus and the smallest ones in the heart muscle tissue. The average size of sarcocysts isolated from diaphragm was 957.6 mm x 112.7 mm. Sarcocysts found in the oesophagus measured 484.1 mm x 194.6 mm and those isolated from the heart muscle attained 305.4 mm x 103.9 m

Opis:
Examinations were carried out in Białowieska Forest, Borecka Forest, Lower Silesian Forest, woods in Olsztyn District, Słowiński National Park, and in experimental hunting areas of the Forest Research Institute in Iława and of the Warsaw Agricultural University in Rogów. Samples of the skin from the ear and nose were taken from 136 shot roe deers. Skin samples were cut into 1-2 mm pieces, incubated in a physiological solution in 25°C for 24 hours and examined for the presence of microfilariae. Microfilariae of Dipetalonema rugosicauda were found in roe deers in all examined hunting grounds. Prevalence of invasion oscillated from 6,6% to 57,1 %. The wide dispersion of D. rugosicauda in Poland is caused by common occurrence in our country of the intermediate host and vector of this nematode - tick Ixodes ricinus.
