“…The pathological changes, including diarrhoea, anorexia, and respiratory tract inflammation in the examined roe deer, had not previously been described in this host species, but they are in accordance with observations described in cattle infected with D. viviparus (Rubin and Lucker 1956) and red deer infected with D. cervi (Pyziel et al 2018). The rather high mortality of the young roe deer observed in the studied area was probably connected to the increase in the lungworm infection caused by D. capreolus.…”

“…Among the clinical symptoms, respiratory distress such as polypnoea, coughing, dehydration, anorexia, diarrhoea and constipation, weight loss or poor weight gain were observed; the post-mortem findings included interstitial and subpleural emphysema and bronchopneumonia, bronchiolitis (Rubin and Lucker 1956), peribronchiolitis, as well as bronchial atelectasis and consolidation (Schneider et al 1991). Infection of D. cervi in red deer was associated with interstitial pneumonia, bronchitis and bronchiolitis, moreover, emphysema, atelectasis and lung tissue congestion were also observed (Pyziel et al 2018). Aguirre et al (1999) conducted a retrospective epidemiologic study to examine the causes of mortality among wild roe deer in Sweden.…”

The poor state of health and increased mortality rate of young roe deer, as reported by South Moravian hunters, caused by the increasing numbers of adult nematodes in the lungs of roe deer prompted us to identify the parasites using a combination of morphological measurements and a phylogenetic SSU rRNA analysis. The study was conducted in a 294 ha game reserve in South Moravia, Czech Republic. Molecular and morphometric techniques were used to identify adult nematodes collected from the respiratory tracts of nine 4–5 months old roe deer in poor health (low body weight of 3–4 kg, poor haircoat quality, and, in some cases, symptoms of diarrhoea). The morphological identification was based on a combination of adult worm characteristics corresponding to Dictyocaulus capreolus. A small subunit rRNA (SSU) partial sequence analysis showed the highest identity scores (99%) corresponding to the sequences of D. capreolus from a roe deer (GenBank: AY168859) from Sweden and the outcomes of the phylogenetic analyses resulted in a tree with a high branch support for two groups, with our sequences forming a well-supported clade with D. capreolus and Dictyocaulus sp. ex Capreolus capreolus (FJ589016) and Dictyocaulus sp. ex Rupicapra rupicapra (FJ589019) sequences from Spain. The examined roe deer have shown symptoms of diarrhoea, anorexia, and respiratory tract inflammation indicating that there might be a connection to the clinical importance of the Dictyocaulus infection.

“…Parasitic invasions are common in European bison e.g. protozoans, gastrointestinal and lung nematodes and may cause severe symptoms including hemorrhagic diarrhea, cachexia and bronchitis, and can have a fatal outcome ( Demiaszkiewicz et al, 2009b ; Jolley and Bardsley, 2006 ; Kita and Anusz, 2006 ; Pyziel et al, 2018b ). Severe damages threatening the reintroduction of E. bison may be caused by gastrointestinal parasites, e.g.…”

It is important to monitor the level of parasitic loads in herds of European bison and to identify threats early enough to prevent their spread to other populations or species. The aim of the present study was to compare the detection sensitivity of two fecal flotation techniques, viz. the modified Willis method (WM) with centrifugation and modified McMaster flotation technique (MM), in the diagnostics of gastrointestinal parasites of European bison before the translocation of animals. Out of 166 feces samples, Eimeria spp. oocysts (84.3% in WM and 71.1% in MM) and Trichostrongylidae eggs (82.5% in WM and 53.6% in MM) predominated. These were accompanied by eggs from Capillaria spp. (prevalence: 13.9% in WM and 3.61% in MM), Nematodirus spp. (prevalence: 18.1% in WM and 4.8% in MM) and Trichuris spp. (prevalence: 12.7% in WM and MM) were identified. The lowest prevalence was noted for cestode eggs of Moniezia spp. (5.4% in WM and 3.0% in MM). The Willis method yielded a higher prevalence of eggs and oocysts than the modified McMaster method, and hence has a higher probability of detecting parasitic structures than the modified McMaster method, especially in cases of very low levels of invasion. As the two methods yield consistent results, it is recommended to use the Willis method for diagnosis of internal parasite infection in European bison. This test offers more sensitive method than McMaster technique of detecting the presence of low levels of a variety of parasite eggs and oocysts in feces, while also being inexpensive and adaptable to field work.
