“…Our investigation has revealed that coccidia are highly prevalent in both grouse species, which is consistent with literature data (Jankovska et al 2012 ; Millán et al 2008 ; Obeso et al 2000 ). However, the prevalence of coccidia in our study was much higher than in literature, which is probably due to the fact that the published data originated from investigations performed on wild grouse and not on birds kept in captivity.…”

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. Results indicate that the average prevalence of Eimeria revealed 72% (average OPG = 3548) and 80% (average OPG = 5220) in capercaillies and black grouse respectively. Most of the Eimeria spp. oocysts were non-sporulated; however, two different morphological types were observed. The phylogenetic analysis of cox-1 and 18S rRNA genes revealed the analyzed Eimeria sequences to belong to two species. In addition, it showed some similarities between both analyzed genes. Most of the sequences obtained from both grouse species coccidia belonged to one species partially homologous to the Eimeria spp. isolated from ring-necked pheasant (approx. 94 and 96% for cox-1 and 18S rRNA genes, respectively). Two strains isolated from capercaillies imported from Russia were related to turkey coccidia: E. innocua and E. dispersa (97–99% homology) in the cox-1 gene analysis and only one of them was related to those Eimeria species in the 18S rRNA gene analysis (98–99% homology).

“…There are reports of coccidiosis infections in wildlife black grouse and capercaillie (Jankovska et al 2012 ; Millán et al 2008 ; Obeso et al 2000 ). However, none of the coccidia that parasite on those species have been studied with the use of molecular methods.…”

“…They accounted for 41% of all the parasites found in the feces (OPG 450-110000), and the infestation was chronic ( Sokół and Gałęcki, 2018 ). The dominance of this parasite in forest Galliformes birds (black grouse and capercaillie) has also been noted by Obeso et al., 2000 , Millán et al., 2008 and Jankovska et al., (2012) .…”

The black grouse ( Tetrao tetrix ) is a forest bird species critically endangered of extinction. Enclosed aviary breeding is among the measures taken to protect the species. Complex factors can affect its reproduction success, including coccidiosis. In this article, corticosterone level (as a reliable biomarker of stress in birds) and prevalence of Eimeria spp. were determined in male black grouse kept in aviary breeding center before, during, and after the reproductive season (called tooting). The correlation between those parameters was also analyzed. The corticosterone level was measured with noninvasive method in fecal samples in an immunoassay. The prevalence of Eimeria spp. was determined by the qualitative (Fülleborn's flotation) and quantitative method (McMaster's method as modified by Raynaud). Results show the occurrence of 3 species of Eimeria spp. in males: Eimeria lyruri , Eimeria nadsoni , and Eimeria nonbrumpti . Infestation with E. lyruri was chronic in nature. A co-invasion of E. lyruri , E. nadsoni , and E. nonbrumpti was observed during (prevalence 60%) and after the tooting (prevalence 40%). The study showed no statistical changes in the oocysts per 1 g of feces ( CORTl ) and oocysts per 1 g of feces ( OPG ) in assays I-III and absence of correlation between CORTl and OPG. The results of this experiment do not support the hypothesis that chronic infestation with Eimeria spp. can induce chronic stress in grouse. But may suggest that males of black grouse are susceptible to infestation with other species of Eimeria spp. during mating season. The knowledge of the level of individual stress and parasitic infestation can be used to take protective actions for this bird species, especially to achieve higher survival rate and bird reproduction rate. Tangible effects will include an assessment of the relationship between individual susceptibility and chronic environmental stress caused by coccidia.

“…Kokcydia te zaliczyć można do pasożytów oligoksenicznych, pasożytujących głównie u przedstawicieli rodziny kurowatych (Phasianidae). Występowanie oocysty E. lyruri wykazano w próbkach kału głuszców, cietrzewi (Lyrurus tetrix), kuropatw skalnych (Alectoris graeca), a także dzięcioła dużego (Dendrocopos major) (8,11,16,17). Ponieważ kokcydia te stwierdzane były do tej pory wyłącznie u ptactwa wolno żyjącego, brak jest badań dotyczących patogenności tego gatunku.…”

“…Hipotezę tę uwierzytelniają badania przeprowadzone na terenie Czech na dzikiej populacji cietrzewi. Wykazano tam obecność obu stwierdzonych przez autorów pasożytów, przy czym, podobnie jak w badaniach własnych, częściej występowało zakaże-nie E. lyruri (67%) niż C. caudinflata (4%) (11). Mała specyficzność gatunkowa obu pasożytów umożliwia krzyżowe zarażenia pomiędzy dwoma gatunkami kuraków leśnych, tym bardziej, że obszary ich wystę-powania na wielu terenach mogą się pokrywać.…”

The western capercaillie breeding program is aimed at the restoration and reintroduction of this bird species in Poland. Parasitic invasions may be one of the factors limiting the breeding effects. The aim of the paper is to present the parasitologic situation in aviary breeding centres in Leżajsk and Wisła Forest Divisions. The study material included 38 samples of faeces of western capercaillie taken from the floor of the aviaries in the breeding centres in Leżajsk and Wisła Forest District. The faeces were studied using flotation, decantation and the quantitative McMaster methods. The presence of only two parasitic genera was detected. Based on the results of morphological analysis, the coccidia was classified as Eimeria lyruri, while nematode as the species Capillaria (syn. Aonchoteca) caudinflata. The total average prevalence of parasitic invasion in the studied samples was 60.5%. In both studied aviaries, the dominating invasion was coccidiosis, with average prevalences of 55.3%. The eggs of nematodes from Capillaria were found in 34.2% of all studied samples. Monoinvasion was present in 31.6% while the mixed invasion of coccidiosis and capillariasis was found in 28.9% cases. Dispersive forms of the parasites were significantly more frequent in the faeces of hens (77.3%) than of cocks (37.5%). No statistically significant differences in invasion extensiveness between the two breeding centres were found. The invasions of both types of parasites in the studied flocks were of a low level (the average OPG was 268.2 while the average EPG of Capillaria sp. was 164.3). The average OPG/EPG values in both breeding centres were similar, which was confirmed by student t-test. Higher values of OPG/EPG were found in samples coming from hens than in those coming from cocks but the differences were insignificant.
