OCCURRENCE OF THE LARGE AMERICAN LIVER FL UKE (FASCIOLOIDES MAGNA) OFTHE DEER IN HUNGARY

Occurrence of the large liver fluke of North-American origin (Fasciolo ides magna), living in the liver of Cervidae, was observed in red deer s of Szigetkoz (an island of Danube in the plain in North-western of H ungary). In a single deer liver sent for laboratory investigations, 10 almost adult flukes were found which could originate from a single, s imultaneous infestation. Of the 10 flukes, only one could be considere d adult (Figure 4). Measuring data of the 10 flukes are shown in a Tab le. Of randomly collected 15 deer faecal samples, 11 contained Fasciol oides ova. Based on this finding, the fluke seems to be wide-spread in the Szigetkoz. Gross-pathological alterations caused by this parasite have been reported (Figs 1, 2, and 3) touching also the epidemiologic al relations of the infestation.
