Tehran. Iran "Review of amphistomes (Trematoda: Paramphistomata) of Iranian domestic ruminants" Sey, O. - Eslami, A. - Parasit, hung. 14: 61-65. 1981-82. ABSTRACT. Histomorphological examinations revealed ten species of amphistomes of which Paramphistomum gracile, Gastrothylax compressus, Carmyerius spatiosus , Cali- cophoron papillosum and Orthocoelium scoliocoelium proved to be new for Iran. Structure of the recovered species and their zoogeographical affinities have been discussed in full length . Amphistome parasites of Iranian domestic ruminants have been reported by BAGHERI (1961), ARFAA (1962), SABBAGHIN et al. (1964), RAFYI et al. (1968) and ESLAMI and FAIZY (1975). The origin of cattle in BAGHERI' s (1961) examinations as well as the species of parasites obtained were not determined. ARFAA (1962) discovered Paramphistomum microbothrium in the Khuzistan Province, by experimentally infecting lamb with metacercariae emerged from naturally infected snails, Bulinus truncatus. RAFYI et al. (1968) gave the following list of Iranian amphistomes: Paramphistomum cervi, P. gotoi, P. microbothrium , P. (now Orthocoelium) orthocoelium, Cotylophoron cotylophorum, Gi- gantocotyle explanation, Gastrothylax crumenifer and Fischoederius sp. More recently P. cervi was repeatedly reported from goat by ESLAMI and FAIZY (1975). Results of the present paper further contribute to our knowledge of amphistomes in Iranian ruminants and an analysis of their zoogeographical affinities is given. MATERIALS and METHODS The study material was collected by A. ESLAMI, the junior authors from 1979 to 1981 at slaughter houses of Tehran and in the southern and eastern parts of Iran. The majority of the samples were derived from cattle and one sample was obtained from sheep (Shiraz). A total of fourteen samples were available for examinations. Flukes, after having been removed from the rumen, were fixed in 10% formalin and median sagittal sections were prepared by the usual method. RESULTS and DISCUSSION In the samples available ten species were recovered, including some described by earlier authors. As the identification of the amphistomes has been reported from Iran so far, based on gross-morphological features, the histomorphological structure of the muscular organs of these species is also presented and illustrated.
