Tables 1-3 summarize the helminth infections of the micromammalian families examined. A deficiency of the collected material was that it contained no summer samples. The prevalence of helminth invasions was also demonstrated by season, such as autumn, winter and spring, respectively.

Table 4 summarizes the species composition of micromammalian synusium and the ratio of infected ones. The number of host specimens investigated was between 159 and 359 (except in the sample from Lubochna, which comprised 65 small mammals only), the rate of helminth infections was 42,60, 32, 53, 87 and 74%, respectively. We presented a cumulative list of helminth species occurring in the Balaton area, and the hosts of each parasitic worm in all territories were investigated (Table 5). It is remarkable that the host specificity of helminths (at generic or family level) was the major factor influencing the species composition in the various localities. E.g. among the 41 parasitic worm species of the Balaton area three trematodes of muskrats occurred only in Balaton samples, because these hosts were hardly investigated in
