AbstractA 3-year-old female fallow deer was subjected to the necropsy and virological testing, due to a suspected infectious disease in the herd of farmed deer in the Southeastern region of Poland. The animal was found negative for the presence of BVDV, BoHV-1, BTV, and EHDV antibodies and BVDV antigen. The toxicological examination did not reveal any coccidiostats, mycotoxins, rodenticides, carbamate pesticides, and organophosphorus pesticides. The flukes found during postmortem examination were first characterised microscopically asFascioloides magnaand later their identity was confirmed by PCR and sequencing. The autopsy revealed lesions characteristic forF. magnainfection, including different size cystic spaces in the liver, filled with brownish mucous fluid and flukes, and black pigment covering the surface of parietal and visceral peritoneum with the highest concentrations localised next to the liver. The changes observed in the liver tissue were typical of liver cirrhosis. The results demonstrated that in Poland, where the cervid farming is developing dynamically, the problem of fascioloidosis is present and may probably exert a significantly negative influence on the productivity of such farms if no antiparasitic treatment is performed.

Abstract The study was conducted in 2012-2013 on 75 fecal samples of red deer from the Lower Silesian Wilderness which were examined to determine the prevalence of Fascioloides magna in the game population. Finding liver fluke eggs in a single sample which were larger in size than Fasciola hepatica eggs indicated that further molecular analysis was necessarily. The partial sequence (116 bp long) of ITS-2 of the investigated eggs was identical to the sequences of F. magna from red deer (Cervus elaphus) (GenBank, EF534993; GenBank, EF534992) and from wapiti deer (Cervus elaphus canadensis) (GenBank, EF534994) from Slovakia, as well as from fallow deer (Dama dama) from the USA (GenBank, EF051080). This is the first molecular confirmation of the occurrence of F. magna in Poland.

  The giant liver fluke, Fascioloides magna, is of interest to wild-life managers, veterinarians and researchers, due to its unusual body size (3–10 cm), high pathogenic potential and because it is continuously spreading to new areas, especially in Europe. Annually, the number of cases of animal infections (mainly cervids and bovids) caused by this fluke is monitored in many European countries, including the Czech Republic (with some foci of prevalence over 90%). During the years 2009 and 2010, 1622 survey forms focused on monitoring of fascioloidosis were distributed in the community of “Czech Inspectors of Hunted Game” (CIHG), and 21.3% of forms containing positive or negative response about F. magna occurrence were returned. The administrative units monitored by particular CIHG, who answered the forms, were geographically equally distributed and therefore we believe that also the recorded distribution of F. magna in wild-life animals reflects the real situation in the Czech Republic. A significant number of cases of F. magna infection were repeatedly reported from areas in the south-west part of the Czech Republic. Moreover, our report contains also some unique records of several new F. magna foci in the western (close to the German border), northern (close to the Polish border) and central parts of the Czech Republic, supporting the assumption that the parasite is spreading further throughout Europe. In five game administrative units F. magna infection was directly confirmed by examination of dissected deer livers or by microscopic examination of coprological samples, followed by isolation of DNA from adults and eggs and further molecular analyses. Fascioloides magna intermediate host snails (Galba truncatula and Radix spp.) were collected during 2009 and 2010 from different localities of the Czech Republic, kept in aquaria, examined for shedding of F. magna cercariae, dissected and parasite/snail DNA was isolated. After PCR with specific primers for parasite/snail internal transcribed region number two (ITS-2) the obtained sequences confirmed identification of the following species: F. magna, G. truncatula, R. peregra, R. lagotis, R. labiata and R. auricularia. Although it has been demonstrated that the number of areas with positive cases of fascioloidosis is still growing, the risk of pathogenic impact of F. magna on populations of free-living animals and farming cervids/bovids is generally underestimated.
