Bioserotypes, Virulence Markers, and Antimicrobial Susceptibility of Strains Isolated from Free-Living Birds.

The risk of meat contamination with poses a threat to consumers and persons who come into contact with bird carcasses. The occurrence of . in the vast majority of migratory game species, the capercaillie, and the black grouse has never been studied in Poland, Europe, or in the world.

Molecular analysis of cox-1 and 18S rRNA gene fragments of Eimeria species isolated from endangered grouse: capercaillie (Tetrao urogallus) and black grouse (Tetrao tetrix).

This paper is the first record describing the molecular analysis of Eimeria species occurring in capercaillie (Tetrao urogallus) and black grouse (Tetrao tetrix) which inhabit northern Eurasia and are species critically endangered of extinction. Actions undertaken to protect endangered species, such as breeding individuals in closed aviaries, could allow saving those birds, but they also pose risk of accidental healing of invasive diseases, like coccidiosis. Therefore, an investigation was conducted on fecal samples collected from the capercaillies and black grouse originating from the Kirov region (Russia) and breeding centers located in Poland.
