Black grouse in Czech Republic and its parasites

Open access


According to the newest data (2010), the state of the black grouse is in decline in the Czech Republic. One of the reasons for this decline is the parasitic infection. The examination of 170 faecal specimens disclosed 6 species of parasites. Helminth eggs were found in 50 % of the examined faecal specimens. The following eggs were found: cestode Hymenolepis spp. (28 %), with the highest prevalence (84 %) and mean intensity (1076 EPG) in spring; nematodes Trichostrongylus tenuis (24 %), and Ascaridia compar (3 %) with a mean intensity of 11 and 12 EPG, respectively. Coccidia infections were present in 1 % of faecal specimens only in spring, with an intensity of 35 OPG. However, in the following year, Eimeria lyruri was the most abundant parasite in the faecal specimens. During the second year of our research, the prevalence of E. lyruri was 28 %; the highest prevalence (67 %) was in summer with an intensity of up to 9433 OPG.
