Wild Life

  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.

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.

Long Term Survey

Summary Fascioloidosis of wild and domestic ruminants is caused by giant liver fluke, Fascioloides magna (Trematoda; Fasciolidae). In Slovakia, the parasite is present in the Danube floodplain forests permanent focus for almost 30 years. Here we provide data on 11-year survey of F. magna acquired from 137 red deer (Cervus elaphus) hunted in the southwestern hunting grounds (districts Komárno and Dunajská Streda). Almost 47 % of all examined deer, including males, females and fawns, were infected with F. magna. During the studied period, the prevalence ranged between 33.3 % (2009) and 63.6 % (2007). Prevalence of fascioloidosis varied between sexes and age categories; while the lowest overall prevalence was detected in females (33.3 %), higher values were documented for red deer males (50.6 %) and fawns (43.3 %). A presence of giant liver fluke in studied regions of southwestern Slovakia deserves future attention and ongoing monitoring due to a possible threat of F. magna infection of domestic ruminants in overlapping regions.

AbstractThe study describes a karyotype of a common parasite of cervids, the giant liver fluke, Fascioloides magna (Trematoda, Platyhelminthes). The chromosome set of F. magna comprises 11 pairs of chromosomes, all classified as subtelocentric except for the submeta-metacentric pair No. 8 and the submetacentric pair No. 10 (2n = 22, n = 1sm + 1sm-m + 9st). The first longest pair is 4.65 μm long and the length decreases continuously to the 1.92 μm length of the last pair No. 11. No distinct secondary constriction has been observed in mitotic preparations. Fluorescent DAPI-staining reveals distinct heterochromatin bands on all 11 chromosome pairs in the centromeric regions; another DAPI-positive bands are localized at the end of the long arms of chromosomes No. 5 and the last less distinct signals appear interstitially on the long arms of the pair No. 6. Synchronous meiotic divisions of 8-spermatocyte groups have been observed during spermatogenesis, similarly with a development of spermatocytes in other trematodes. In the first two stages of heterotypic spermatocyte division, 11 bivalents (n = 11) are regularly observed, confirming the diploid number of 22 elements. Furthermore, the present analysis summarises and discusses available cytogenetic data on Fasciolidae flukes suitable for future studies on taxonomy or phylogenetic interrelationships within the family.

Giant Liver Fluke

AbstractThe giant liver fluke, Fascioloides magna, is a veterinary important liver parasite of free living and domestic ruminants. This originally North American parasite was introduced along with its cervid hosts to Europe where it has established three permanent natural foci - in northern Italy, central and southern parts of the Czech Republic and the Danube floodplain forests. The first record on fascioloidosis in Poland originated from the Lower Silesian Forest in south-western Poland and since then an occurrence of F. magna in this country has not been documented. Recently, the parasitological examination of red deer (Cervus elaphus elaphus) from the Lower Silesian Wilderness (south-western Poland) revealed the presence of F. magna eggs. In order to determine the genetic interrelationships of the Polish giant liver fluke individuals, they were molecularly analyzed by mitochondrial cytochrome c oxidase subunit I (cox1) and nicotinamide dehydrogenase subunit I (nad1) and compared with haplotypes of so far studied European populations of the parasite. The study revealed the genetic uniformity of F. magna specimens from Poland with part of individuals from the Czech natural focus.Note: Nucleotide sequence data reported in this paper are available in the GenBank
