During post mortem examination of 181 sheep, a total of 16 male and 26 female nematodes were identified as Marshallagia dentispicularis. This is the first report of the parasite in European sheep. A complete description of the species is given.

Ashworthius sidemi, a nematode belonging to the family of Trichostrongylidae, is a primary parasite of the Asian deer, mainly sika deer (Cervus nippon), with which it was introduced to Ukraine, as well as Slovakia, the Czech Republic and France. Migrating red deer carried this parasite from neighboring countries to Polish territory. Until now, in Poland, this parasite has been recorded in European bison, red deer, roe deer and fallow deer. As a result of post-mortem examinations of 10 elk, 2 of them from the Augustów Forest and Biebrza Marshes, A. sidemi were found in abomasa for the first time in Poland. The intensity of the invasions was 120 and 7 specimens, respectively. This finding of Ashworthius sidemi in elk indicates a further expansion of the focus of ashworthiosis in BiaŁowieża towards the north into the Biebrza Marshes and the Augustowska Forest. The growth of the elk population and their tendency for long distance migrations can contribute to the spread of the parasitosis in much greater distances than deer. On the basis of our own research and data from the literature, the current spread of ashworthiosis in Poland is discussed.

Two females of beaver from north-east Poland were necropsied. Moreover, 15 samples of feaces were examinated. Both necropsied beavers were infected with 46 and 362 specimens of trematode Stichorchis subtriquetrus (RUDOLPHI 1814). In stomach of one beaver were found 2800 specimens of nematode Travassosius rufus Khalil, 1922. It was the first registration of this species in Poland. Coproscopical examination showed eggs of S. subtriquetrus in all 15 fecal samples and eggs T. rufus in 5 samples.

Asworthius sidemi Schulz, 1933 is a blood sucking gastrointestinal nematode, primarily typical for Asiatic deer. It was found for the first time in Poland in European bison in 1997. To estimate the level of invasion of A. sidemi and histopathological changes connected with the presence of the parasite in the years 2004-2007 parasitological and histopathological examinations of 54 European bison from Białowieża Forest were carried out. Parasitological examination was carried out by the sedimentation method and A. sidemi were diagnosed under a binocular microscope. Samples for histological examination were collected from the abomasum and duodenum walls as well as from regional lymph nodes. Tissue samples were then fixed with 10% buffered formalin, embedded in paraffin, cut in to 5 μm thick sections and stained with hematoxylin and eosin (H&E). Parasitological examinations showed the presence of fourth stage larvae and juvenile forms of A. sidemi. The maximal intensity of invasion rose systematically from 4470 A. sidemi nematodes in 2004/2005 to 44310 in 2006/2007. Histopathological examinations showed infiltrations of inflammatory cells in the walls of abomasa and duodena at various levels of intensity (mainly lymphoid cells and eosinophils), hyperemiae, oedemae and lesions of mucosa and proliferation of lymphatic follicles. In individual cases of dysplasia of epithelial cells, atrophy or hyperplasia of glands and the presence of parasites in the lumen or walls of the abomasum/duodenum were observed. In one case, parasitic nodules were found. In regional lymph nodes proliferation of lymphatic follicles, presence of eosinophils and desolation of reproduction centers were observed. Intensification of histopathological changes was connected to a considerable degree with the developmental stage of A. sidemi as shown by parasitological examination.

The aim of the study was to determine the efficiency of a formulation containing essential oils from Origanum vulgare (Lamiacea) and Citrus spp. (Citraceae) in limiting the prevalence and intensity of parasitic invasions in ewes kept in an indoor management system. The study material was a group of 222 mother ewes of Polish Lowland breed. During the entire experiment, the animals were kept in an indoor management system with uniform environmental conditions. On the basis of the parasitologic analysis, the flock was divided into three groups. All groups were uniform from the perspective of genetic traits, age and environmental conditions. The differentiating factor was the addition of a preparation containing essential oils from Origanum vulgare and Citrus spp. in the dose of 4 kg/ton of feed. Group 1 – control group, non-supplemented diet (74 mother ewes); Group 2 – supplemented diet from third month of pregnancy to lambing (73 mother ewes); Group 3 – supplemented diet from third month of pregnancy to weaning (75 mother ewes). The experiment involved parasitologic tests aimed at the determination of prevalence and intensity of invasions of gastrointestinal parasites in mother ewes. The study material was faeces collected from the rectum of mother ewes before the start of the experiment and on day 2, 28, 42, 56 and 70 after lambing. On the basis of the observations, it was shown that continuous use of the preparation during the whole experimental period had a beneficial impact on reducing the prevalence of invasions of Eimeria spp. and Capillaria. However, it must be stressed that both the prevalence and the intensity of parasitic invasions in the studied flock was relatively low, and so the use of such a preventive method was feasible.

Between 2003-2007, abomasa of 91 European bison (Bison bonasus), 4 red deer (Cervus elaphus) and 2 roe deer (Capreolus capreolus) shot in the Białowieża Primeval Forest (Poland) were examined for worms presence. All the animals examined were infected with nematodes A. sidemi with an exception of one bison, that was shot in year 2003. There was much higher average intensity of invasion in bison (5529), than in red deer (85) and in roe deer (1837). The animals were shot in a period from December to March, and the nematodes found in them were fourth stage larvae and immature adult specimens. In the following years of examinations, a gradual increase in average intensity of infection was observed. In 2007, it reached in bison 10814 nematodes. Maximum intensity of invasion was found in this year as well and it reached 44310 nematodes in one bison. Pathological changes such as an oedema, hyperaemia and effusion in the abomasum and duodenum mucosa were most clearly seen in the calves that were highly infected. These changes probably lead to chronic diarrhoea, deterioration and deaths of young animals.
