HARDOVÁ, 1955; SEBEK, 1970) and in A. sylvaticus (CERNÁ, 1957; SEBEK, 1970), in Germany also in both host-species (KRAMPITZ, 1964), in England in A. sylvaticus (COX, 1970), in Yugoslavia in A. sylvaticus and in A. flavicollis (SEBEK, 1976); besides, Hepatozoon belonging in all probability to the species H. sylvatici was there found also in Apodemus agrárius and in A. mystacinus (SEBEK, 1976). SEBEK et al. (1970) established H. sylvatici in Bulgaria in A. sylvaticus. I found two infected A. flavicollis at Pinye, and another one at Somhegypuszta. The two A. sylvaticus occurred at Tómalom and at Fertőboz, respectively. H. erhardovae is also distributed in its specific host C. glareolus probably over all Europe. It has been known from Czechoslovakia (ERHARDOVÁ, 1955; CERNÁ, 1957; SEBEK, 1970), Germany (KRAMPITZ, 1964), Austria (MAHNERT, 1972), England (COX, 1970) and Yugoslavia (SEBEK, 1976). In western Hungary were the positive C. glareolus cought at Tómalom (2 specimens), Fertőboz (2 specimens) and at Városlöd (1 specimen). The infection rate of small terrestrial mammals in western Hungary was not compared with that . in different european countries. It is known, that Hepatozoon is frequent in the organs - lung, spleen, liver - but it is rare in the blood. Unfortunately, we had only blood smears for our examination. GRAHAMELLA Grahamellas are very frequent parasites of the erythrocytes of small mammals. KIKUTH (1932) reported their 34 host species, KRAMPITZ and KLEINSCHMIDT (1960) found Grahamellas in 15 species of Central - and South European small mammals. Even heavy infections with Grahamellas are known to be harmless to the host (KRAMPITZ and KLEINSCHMIDT, 1960). Taxonomy of Grahamellas is not clear as yet; most species were described only on the basis of the finding in a new host species. I agree with MAHNERT (1972) that the present state of knowledge is not adequate for their specific determination as pointed out by KRAMPITZ and KLEINSCHMIDT (1960). Grahamellas are common to occur in A. flavicollis, A. sylvaticus, C. glareolus and Microtus arvalis as these parasites have been recorded from these hosts in Germany (KRAMPITZ and KLEINSCHMIDT, 1960), Austria (without Microtus arvalis) (MAHNERT, 1972), Czechoslovakia (SEBEK, 1960; 1975) and Yugoslavia (SEBEK, 1976). The occurrence of Grahamella from Crocidura suaveolens and C. leucodon seems to be new host record. Percentage distribution of the infection greatly varies from place to place but the mean incidence of Grahamellas in the free living small mammals in western Hungary is high 30. 8% in A. sylvaticus, 16.9% in A. flavicollis and 14. 1% in C. glareolus. Positive specimens of C. suaveolens and C. leucodon originated from Fertőboz. Those of A. flavicollis from aU the localities except Tótvázsony. Infection in C. glareolus was established in Sopron- Tómalom, Fertőboz, Gic and Som hegy puszta, and the single infected M. arvalis specimen was found at Gic. It was somewhat surprising that Babesia microti did not occur in the present material from western Hungary. In Central- and South-eastern Europe, it has been found: in Czechoslovakia in C. glareolus, M. arvalis and M. agrestis (SEBEK, 1975a), in Austria in S. araneus, Pitymys subterraneus

, C. glareolus, M. agrestis and Microtus nivalis (MAHNERT, 1972), in Yugoslavia in Neomys anomalus, A. ajgrarius, A. flavicollis and in Mus musculus (SEBEK,. 1976) and in Bulgaria in A. sylvaticus (SEBEK, 1976). Certainly, our negative findings in western Hungary do not testify the absence of Babesia microti in Hungary, because only a small number of small terrestrial mammals was examined.
