Fascioloides magna, a parasite of red deer in Lower Silesian Wilderness
Fascioloides magna, a liver trematode introduced into Europe in the 19th century from North America is an important parasite of wild and domestic ruminants. In order to confirm the occurrence of this fluke in Poland, a parasitological autopsy was conducted on 30 deer shot in the winter of 2013/2014 in Lower Silesian Wilderness. In addition, samples of faeces of those animals were examined by a decantation method. It was found that two doe were infected with F. magna flukes, so the prevalence amounted to 6.6%. Two specimens of flukes were found in the liver of one doe, and nine were found in the other. The livers were enlarged, and dark brown or black blotchy pigmentation and fibrinous tags were observed on their surface and on the section. In the parenchyma of the organ, numerous wholes capsules (pseudocysts) were found. They were filled with bloody or dark brown liquid, in which flukes were located. Many parasite eggs were also found in faeces.
