Die Verbreitung von Opisthorchis felineus (RIV.) und anderen Katzenhelminthen in Ostpreussen

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

“…Of those, the most recent human outbreaks were reported from Italy, where more than 200 people were infected through the consumption of raw ish coming from two central lakes of the same country [47][48][49][50][51][52]. To the authors' knowledge, human infection records of opisthorchiasis in the Iberian Peninsula are very old, dating back to 1932 [16]. Those were reported from Spain (Bilbao) and since then, only one imported case has been published from a patient who immigrated to Spain from the Thailand-Laos region of Asia [53].…”

“…Those were reported from Spain (Bilbao) and since then, only one imported case has been published from a patient who immigrated to Spain from the Thailand-Laos region of Asia [53]. Although no more human cases have been reported so far, O. felineus is present in the Iberian Peninsula as it has been found in cat in Vila Real (Portugal) [10] and in red fox in Malcata (Portugal) [13] and provinces of Spain [17] and in a cyprinid ish of the genus Leuciscus in Guadalquivir River (near Cordoba) in Spain [16]. In the case of M. bilis, there is not a detailed status of the human infections [54], but animal cases of metorchiasis have been reported in the common genet in Cabrerizos, Montseny and the north-east of Spain [18][19][20][21] and in the red fox in the Ebro valley in Spain and in Malcata in Portugal [13,17,22].…”

“…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. Although no more human cases have been reported so far, recent infections of opisthorchiasis have been reported in cat [10] and red fox [13,17].…”

Opisthorchiidosis-A Review

“…Already at the beginning of the 20 th century, human cases of opisthorchosis were known from this region [81]. Later on, a study revealed that 79 -88% of the domestic cats in this region were infected and a maximum burden of more than 1000 flukes was counted [61]. Along with the study of the helminth fauna of wild carnivores in Belarus, O. felineus was encountered in wolves, otters, raccoon dogs and red foxes [82][83][84][85].…”

“…Since most of the species have a narrow spectrum of snails as 1 st intermediate hosts, the occurrence of these flukes depends highly on the distribution of the snails. Distribution maps for O. felineus are based on fluke findings in the final hosts [61][62][63][64]. Wild carnivores with a limited home range like foxes are good indicators for the presence of opisthorchiid flukes.…”
