Sažetak
Digenean trematode Fascioloides magna (large American liver fluke) is a parasite of primarily North American deer species. According to the genetic evidences it was introduced to Europe at least two times, due to the introduction of for Europe exotic deer species like white-tailed deer or wapiti. Finding suitable conditions maintaining of its life cycle, it expanded its distribution through the Danube river valley and continued with all the surrounding floodplains. It has been diagnosed in Croatia 16 years ago and has expanded from Baranja region to almost central Croatia. In wild animals we can find three different hosts depending on the pathogenesis, clinical signs and manifestation of the disease. These include definitive hosts, dead-end hosts and aberrant hosts. Definitive hosts in Croatia are red deer and fallow deer. Parasites mature in the pseudocyst in the liver parenchyma. In each pseudocyst are two or more mature flukes which are producing high number of eggs. Some of the pseudocysts have communication with the bile ducts and this is the way through which they are excreting the eggs to the gastrointestinal system. In dead end hosts (wild boar) parasite reaches the liver, but rarely matures, and if eggs are produced they are not shed to the environment. Parasite stays isolated inside the pseudocyst. The aberrant hosts, there is no pseudocyst formation and flukes constantly migrate leading to excessive tissue damage. Aberrant wildlife hosts in Croatia are roe deer, mouflon and chamois. This hosts usually succumb to the disease due to excessive bleeding and destruction of the liver tissue. Infection with F. magna is also possible in domestic ungulates. Physiologically, parasites are trying to live in balance with their final hosts, which enables them both to survive. This three totally different manifestations of infection by F. magna are interesting for future research and for monitoring of host-pathogen relationship.
