Examination of Amphistomes (Trematoda: Paramphistomata) Parasitizing in Egyptian Ruminants Dr. Ottó SEY Department of Zoology, College of Education, Pécs "Examination of amphistomes (Trematoda: Paramphistomata) parasitizing in Egyptian ruminants"-Sey, O. - Parasit. Hung. 10. 47-50. 1977. ABSTRACT. Three species of rumen flukes, Paramphistomum gotoi Fukui, 1922; P. microbothrium Fischoeder, 1901 and Carmyerius gregarius (Looss, 1896) have been recovered from Egyptian ruminants. P. microbothrium was found in every host species examined (Bubalus bubalis, Bos taurus, Ovis aries, Camelus dromedarius, Capra hircus and Capranubiana), while P. gotoi and C. gregarius occurred in buffalo only. P. cervi appears not to occur in Egypt. The species_ formerly identified as P. cervi is in fact P. microbothrium. In the relatively scarce literary data referring to amphistomes of Egyptian ruminants the occurrence of the following four species can be ascertained: Paramphistomum cervi (Zeder, 1790); P. gotoi Fukui, 1922; P. microbothrium Fischoeder, 1901 and Carmyerius gregarius (Looss, 1896). Opinions, however, vary on the presence of P. cervi in this country: EZZAT (1945, 1949) and ABDEL-GHANI (1961) regarded this species to be the commonest rumen fluke in Egypt while others (NÂSMARK, 1937; DINNIK 1961; SEY, 1976) were of the opinion that it was P. microbothrium . Besides reviewing amphistomes of rumaints in Egypt, in the present paper special consideration is given to the possibility of the occurrence of P. cervi in the country. Materials and Methods From October 1973 to March 1974 rumina of 142 buffalo, 120 cattle, 98 sheep, 8 goats and 5 camels were examined for amphistomes in the slaughter-houses of Cairo and Alexandria, Flukes after having been removed from the rumen were fixed in AFA and stored in 70 per cent alcohol. Median sagittal sections were prepared by the usual method. Besides this collection, the amphistome material deposited in the Parasitology Section, National Research Centre, Doukki, Cairo (from Camelus dromedarius and Capra hircus) and Parasitology Department, Al-Ahzar University, Cairo (from Capra nubiana) were also made available for examination. Results and Discussion On the basis of gross morphological examination and of histological structure of the muscular organs of the material three species have been identified. Paramphistomum microbothrium Fischoeder, 1901 This species occurred in all host species; goats and camels examined by myself, however, harboured no amphistomes; incidence was 78 per cent in buffalo, 72 per cent in cattle and 68 per cent in sheep. It was LOOSS (1896) who described P. cervi (= Amphistoma conicum Rud. , 1809 of older authors) first in Egypt but in 1912 he came to the conclusion that the species believed to be 47
