Parasit. Hung. 11. 1978 Examination of Rumen Flukes (Trematoda: Paraniphintomata) of Cattle in Rumania Dr. Ottó SEY Department of Zoology. College Education, Pécs "Examination of rumen flukes (Trematoda: Paramphistomata) of cattle in Rumania" - Sey, O. - Parasit. Hung. 11_. 23-25. 1978. ABSTRACT. Four species of rumen flukes, Paramphistomum cervi (Zeder, 1790), P. daubneyi Dinnik, 1962, P. gotoi Fukui, 1922 and P. ichikawai Fukui, 1922 were recovered in samples collected in the areas of Bucharest, Cluj, Iasi and Tulcea. P. daubneyi, P. gotoi and P. ichikawai are new for Rumania and this is the first report on the occurrence of P. gotoi in Central Europe. The most important specific features of these species are discussed. While examining helminth parasites of the Rumanian domestic ruminants, special attention has not been paid to the species of rumen flukes. Having followed the traditional notion that rumen flukes occurring in Central Europe are identical with Paramphistomum cervi (Zeder, 1790), rumen flukes found in different parts of Rumania have also been regarded as members of this species (OLTEANU and LUNGU, 1961; OLTEANU et al. 1962; TUDOR and ANTON, 1968). The present paper attempts to ascertain species of rumen flukes on the basis of the histo-morphological structure of their muscular organs. Material and Methods The test material was collected at the slaughter houses, Bucharest, Cluj, Iasi and Tulcea in 1977. In the last case cattle came from Luncavita, in the others the origin of the cattle was not detectable. Ten median sagittal sections, each 8-lOjn thick, were prepared from every sample to be stained in haem atoxyline and eosin in the usualmicrotechnical way. Result* and Discussion Four species of rumen flukes have been recovered in the test material available. Paramphistomum cervi (Zeder, 1790) This species has been found in every sample except Bucharest's. Accordingly, this fluke seems to be a common species here indeed, but it should be remembered - as is indicated by the results here - that this name might obviously include other species, too. Its muscular organs are of Liorchis (pharynx, Fig. 1), Gracile (genital atrium, Fig. 4) and Par am phi s torn u m (acetabulum, Fig. 8) type. The structure of these organs deviates at two places from that described by NASMARK (1937). In Näsmark'

s point of view the pharynx of P. cervi is "provided with small, inconsiderable internal papillas". Re-examining the only slide found in NASMARK's collection in the Naturhistoriska Riksmuseet, Sweden papillae of 25 u in length could be recognized like to our material.
