Kriska, T.: Parasitic helminths of house mouse (Mus musculus Linnaeus, 1758) in Hungary

Materials and methods This study is based on the collection of parasitic helminths otMus musculus which have been collected since 1965 in the Parasitological Collection of the Zoological Department of the Hungarian Natural History Museum. The host animals were collected in various localities of Hungary by the parasitological staff and mammalogists of the Hungarian Natural History Museum (Gábor Csorba, András Demeter, András Gubányi, István Matskási, Ferenc Mészáros, Éva Murai, István Szabó, György Topái); 129 mice specimens originate from the Buda Hills (Nagykovácsi), and were captured with living traps for helminthological investigations by Lajos Zombori, hymenopterologist. Some other institutions such as Pannon Agricultural University Keszthely and some collectors such as Béla Edelényi, József Rékási, Ottó Sey also presented some individuals. These materials were completed with my own collections from areas where there had been no collections before (Mátra Mts and Somogy county). Altogether 590 host animals were collected from 60 localities (see Fig.l), from these 488 tapeworms and 4870 nematode specimens were found. The mice were trapped either by pitfall traps or by living traps. In the case of the latter method animal were killed with chloroform. The animals were dissected and the intestines and body cavities were examined. The dissections and the stained tapeworm preparations were made by Mrs Etelka Vajda. The nematodes were fixed in hot Barbagallo (2.5% formalin) solutions while the tapeworms were fixed and preserved by using 5% formalin solution. The nematodes were translucenced in lactophenol. Whole mount preparation of tapeworms were stained with acetic carmine or Ehrlich's haematoxylin. Rostellar hooks and eggs were studied in Berlese solution. Cestodes were identified according to the papers of Genov (1984) and Schmidt (1986), while the nematodes according to the papers and systems of Genov (1984) and Yamaguti (1961).
