A new occurrence of Eimeria alces (Apicomplexa: Eimeridae) in elk (Alces alces) in East Poland.

A total of 114 elk faecal samples from the Polesie National Park and adjacent forest districts were examined in 2013 and 2014. Three samples were positive. The positive samples were from the village of Wereszczyn, the Sobibor forest district, and the Polesie National Park and Forest district, Parczew.

The prevalence and distribution of Dirofilaria repens in dogs in the Mazovian Province of central-eastern Poland.

The aim of this study was to determine the prevalence and distribution of canine dirofilariosis from different districts of the Mazovian Province in central-eastern Poland. 462 dogs aged from 1.5-14 years were examined for dirofilariosis.

The first detection of nematodes Ashworthius sidemi in elk Alces alces (L.) in Poland and remarks of ashworthiosis foci limitations.

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.

Nematodes of the large intestine of the European bison of the Białowieza National Park.

The present study was conducted on 31 males and females of the European bison, eliminated during the winter seasons 2007-2011 in the Białowieza Primeval Forest, Poland. The caeca of 14 free-ranging bison, aged from 3 months up to 16 years, the most favorable infection site for the large intestine nematodes, were investigated during the winter of 2007/2008. The parasitological autopsies of the large intestines of 9 free-ranging bison aged from 5 months up to 10 years as well as 9 bison kept in the close reserves aged from one up to 20 years were done during the winter seasons of 2008-2011 to determine localization of nematodes in large intestine and the total intensity of parasite infection.

[The way of penetration of first stage larvae of Elaphostrongylus cervi (Nematoda, Protostrongylidae) to the intermediate host and their development to the invasive stage].

The aim of the study was the way of penetration of the first stage larvae of Elaphostrongylus cervi to the intermediate host and their development to the invasive stage. The first stage larvae of E. cervi penetrate to the body of a snail by the epithelium of its foot, and localise in tissue of muscles.

Elaphostrongylus cervi is a parasite of skeletal muscles and central nervous system of wild and farm red deer in Europe and Asia. Numerous species of terrestrial snails can be its intermediate hosts. Considering the fact that invasive larvae of E.

Elaphostrongylus cervi is a parasite of the family Protostrongylidae, occurring in cervids in Eurasia. This nematode has hitherto been recorded in some woodland areas in Poland. The current distribution of E.

[The first foci of dirofilariosis of dogs evoked by Dirofilaria repens Railliet et Henry, 1911 in central Poland].

Dirofilariosis is caused by nematodes Dirofilaria repens Railliet et Henry, 1911. This parasitosis is widely distributed in south Europe among dogs, cats and wild carnivorous. It occurs also in Asia and Africa.
