Contribution to the Knowledge of Helminths of Rodents in Roumania Dr. Ferenc MÉSZÁROS — Dr. Éva MURAI Zoological Department of the Hungarian Natural History Museum, Budapest "Contribution to the knowledge of helminths of rodents in Roumania" - Mészáros, F. Murai, É. - Parasit. Hung. 12. 55-70. 1979. ABSTRACT. The helmints of 9 rodent species were examined at 3 localities (Mt. Retezat, Mt. Rodnei and Mt. Gilau) and the occurrence of 9 tapeworm species (Ca- tenotaenia cricetorum, C. pusilla

, Anopiocephaloides dentata

, Paranoplocephala sp., Hymenolepis diminuta, H. horrida, H. asymmetrica

, Taenia tenuicollis larv., Hydatigera taeniaeformis larv

. ), and 14 nematode species (Heligmosomum costel- latum

, H. mixtum, Heligmosomoides polygyrus polygyrus, H. glareoli

, Boreostron- gylus minutus, Syphacia nigeriana

, S. frederici

, S. muris, S

. stroma, Aspiculuris tefcraptera

, Gongylonema neoplasticum, Rictularia proni, Trichocephalus muris, Capillaria annulosa) are recorded. Several studies deal with the helminth fauna of rodents in Roumania (CHIRIACand BARBU, 1962, 1963; CHIRIAC and HAMAR, 1966; POPESCU and BARBU, 1971, POPESCU et al. 1974), however there are few data available from the Carpathian Mountains and from the Apuseni Mountains. We have received for identification helminth-material from Dr. O.S. WAGNER (Frankfurt am Main, FRG) coUected during his expedition in Roumania. The material originated from 3 areas: Retezat Mountains (From 11 to 29 July, 1971, altitude 800-2100 m); Rodnei Mountains (From 21 August to 1 September, 1971, altitude 625-1700 m); Gilau Mountains (From 4 to 15 August, 1971, altitude 450-750 m). Detailed data on hosts and geographical conditions of the localities can be found in WAGNER's (1974, 1976) studies. In the 3 Rattus norvegicus, 9 Mus musculus spicilegus, 34 Apodemus flavicollis, 23 A. sylvaticus, 1 Microtus arvalis, 8 M. agrestis, 13 M. nivalis, 42 Clethrionomys glareolus, and 7 Pitymys subterraneus examined, 9 tapeworm species and 14 nematode species were found. Their occurrence can be seen in Table 1 as per localities and hosts.
