Fatal and sp. co-infestation in wolves () at the Białowieża National Park, Poland - is it a consequence of climate change?

Introduction: In winter 2021/2022, a wolf population in the primeval Białowieża Forest in Poland was struck by an outbreak of severe mange caused by mixed infestations of and mites. We present an epidemiological analysis of this mange which caused significant morbidity and mortality.

Material And Methods: Ten sites known for wolf activity were monitored by camera trapping.

Prevalence and Genotyping of Strains from Wild Animals, European Bison () and Eurasian Moose () in Poland.

Wild large ungulates, like European bison () and Eurasian moose (), form an important part of the circulation of , a Gram-negative, intracellular, tick-transmitted bacterium, in the natural environment. Bison and moose tissue samples were subjected to rDNA, and partial gene marker amplification with specific primers using various variants of PCR. Out of 42 examined individuals, sp.

An attempt to deworm European bison (Bison bonasus) in the European Bison Breeding Center of Białowieża National Park with Alphalben (albendazole).

Parasitic infections are one of the most important factors affecting the health and condition of wild ruminants, including bison, particularly those kept in closed breeding, and regular deworming is important. The aim of this study was to investigate the effectiveness of deworming European bison in BNP (Białowieża National Park) reserves with Alphalben (albendazole). The drug was administered orally at a dose of 15 mg/kg body weight.

The Nematodes Thelazia gulosa Railiet and Henry, 1910 and Thelazia skrjabini Erschov, 1928 as a Cause of Blindness in European Bison (Bison bonasus) in Poland.

Purpose: The nematodes of the genus Thelazia are the cause of eye diseases of wild and domestic ruminants throughout the world. The aim of the study was to describe clinical cases of thelasiosis in European bison (Bison bonasus) in Poland, and provide morphometrical features of Thelazia gulosa Railiet and Henry, 1910 and Thelazia skrjabini Erschov, 1928 regarded as potentially useful for species differentiation METHODS: The conjunctival sacs, tear ducts, the surface of the cornea and nicitating membrane collected from bison were rinsed with saline solution. Any nematodes isolated from the sediment were subjected to morphometric analysis.
