The discovery history of opisthorchiid flukes dates back more than 200 years. The life cycle of these liver flukes includes prosobranch snails as the first and a big variety of freshwater fish as the second intermediate hosts. Opisthorchis felineus, O. viverrini and Clonorchis sinensis are species of major medical importance, while sporadic cases of human infection with other representatives of this family are also documented in the literature. There are estimations that 17 million people are infected and more than 350 million people are at risk, mainly in Asian countries. Although opisthorchiid flukes live in the bile ducts of the liver and in the gall bladder, they can affect surrounding liver tissue and even other organs. They are also known to induce the production of autoantibodies as well as allergic reactions. However, the main medical significance is their role in the formation of malignant tumors. Since the clinical symptoms are not specific, a diagnosis must be confirmed by parasitological examination or the detection of antibodies. Apart from coproscopical methods, there are more recent and highly specific assays available, like the detection of coproantigen or the detection of DNA. Praziquantel is the drug of choice for the treatment of opisthorchiidosis. In order to prevent infection, consumption of raw flesh of freshwater fish must be avoided.

“…Amongst European opisthorchiids, O. felineus is the best-studied species. Sporadic findings of this fluke were made in Portugal [65], Spain [66], Switzerland and France [67]. It was also found in Italy in cats, dogs, and red foxes [5,68].…”

“…Within Eurasia, O. felineus has been found in France, Germany, Greece, Italy, Russia, Poland, Portugal and Spain [10,11] and Metorchis bilis in Denmark, France, Germany, Sweden, Croatia, England, Russia, Portugal and Spain [12][13][14][15]. To the authors' knowledge, autochthonous cases of human opisthorchiasis in the Iberian Peninsula date back to before 1932 [16], so its conirmation is doubtful.…”

Iberian Distribution of the Freshwater Snail Genus Bithynia Leach, 1818 (Mollusca: Truncatelloidea), Vector of Opisthorchiasis and Metorchiasis

Background:Opisthorchis felineus and Metorchis bilis are trematodes that cause opisthorchiasis and metorchiasis, respectively. The freshwater snails Bithynia hispanica and B. tentaculata are the respective intermediate hosts for these parasites in the Iberian Peninsula, where both parasites are present. Methods:To study the distribution of these snail species, an exhaustive literature review and revision of museum collections was performed. Results:A total of 370 localities were compiled and mapped. B. tentaculata were found throughout the Iberian Peninsula, both in Spain and Portugal, while B. hispanica was found only in the Mediterranean coast of Spain. Conclusion:Knowing the distribution of the Bithynia species found in the Iberian Peninsula is highlighted in terms of public health, as the presence of the snail is related to the presence of the disease and can be used as a tool to face future outbreaks.

“…In 1962, Erhardt and colleagues reported O. felineus in the final hosts in most European countries [13]. Recently human and animal infections in the European Union have been reported in Germany [14][15][16][17], Italy [18][19][20], Portugal [21], Greece [22] and the Netherlands [23]. Yet, natural populations of O. felineus have only been described for Italy and Germany [14,18].…”

Low Genetic Diversity in Wide-Spread Eurasian Liver Fluke Opisthorchis felineus Suggests Special Demographic History of This Trematode Species

2017

Opisthorchis felineus or Siberian liver fluke is a trematode parasite (Opisthorchiidae) that infects the hepato-biliary system of humans and other mammals. Despite its public health significance, this wide-spread Eurasian species is one of the most poorly studied human liver flukes and nothing is known about its population genetic structure and demographic history. In this paper, we attempt to fill this gap for the first time and to explore the genetic diversity in O. felineus populations from Eastern Europe (Ukraine, European part of Russia), Northern Asia (Siberia) and Central Asia (Northern Kazakhstan). Analysis of marker DNA fragments from O. felineus mitochondrial cytochrome c oxidase subunit 1 and 3 (cox1, cox3) and nuclear rDNA internal transcribed spacer 1 (ITS1) sequences revealed that genetic diversity is very low across the large geographic range of this species. Microevolutionary processes in populations of trematodes may well be influenced by their peculiar biology. Nevertheless, we suggest that lack of population genetics structure observed in O. felineus can be primarily explained by the Pleistocene glacial events and subsequent sudden population growth from a very limited group of founders. Rapid range expansion of O. felineus through Asian and European territories after severe bottleneck points to a high dispersal potential of this trematode species.
