Evaluation of susceptibility to pyrazinamide and streptomycin, isoniazid, rifampin and ethambutol of Mycobacterium caprae strains isolated from European bison (Bison bonasus caucasicus) in the Bieszczady Mountains (Southern Poland).

The material for drug resistance testing was 28 strains of Mycobacterium caprae isolated from tissue collected post mortem from a free-living Bieszczady Mountain European bison (Bison bonasus caucasicus) herd. All drug susceptibility tests were carried out on an automated Bactec mycobacterial growth indicator tube (MGIT) 960 system, using Bactec MGIT 960 streptomycin, isoniazid, rifampin and ethambutol (S.I.

Serologic Evidence of Exposure to Leishmania infantum in Captive and Free-ranging European Bison (Bison bonasus) in Poland, 2017-23 .

The European Bison (Bison bonasus) is the largest mammal in Europe and is classified as an endangered species. Leishmaniosis is a vector-borne disease caused by the protozoan Leishmania infantum. In general, this infection has been associated with dogs, cats, and humans.

Infectious keratoconjunctivitis in European bison (Bison bonasus) in Poland: risk factors, epidemiology and anatomopathological changes with analysis of potential role of Thelazia nematodes in the disease development.

Background: Infectious keratoconjunctivitis (IKC) is a common ocular disease of ruminants worldwide. Recently, an outbreak of infectious keratoconjunctivitis was observed in the European bison in Poland. Hundreds of animals show conjunctival congestion, corneal opacity, and ulceration, leading to total blindness.

The variety of abomasal nematode communities of captive and free-roaming populations of European bison, (L.): a morphometric and molecular approach.

Most studies concerning parasitic infections in European bison have been performed on free-ranging animals: comparatively little is known about the abomasal nematodes of captive wisents, which are widely used in reintroduction programmes. The aim of the study was to determine the infection level and species composition of abomasal nematodes in captive European bison in enclosures (including zoos) and breeding centres compared to free-ranging individuals. It also includes a morphological analysis of the parasites based on figures and measurement data.

tuberculosis in a captive lion in Ukraine - Case Report.

. Because of the armed conflict in Ukraine, companion, farm and captive wild animals have been moved in a simplified procedure across the Polish-Ukrainian border. For that reason, in 2022, Poznań Zoo provided support for almost 200 wild animals before movement to facilities in other countries.
