[Heterogeneity of populations of the mollusc Bithynia inflata according to the degree of trematode infestation in opisthorchiasis foci].
Results of studies of differences in the infection rate of natural populations of Bithynia inflata with trematodes (including Opisthorchis felineus) in the nidi of opisthorchiasis in the Sumsk and Chernigov Districts of the Ukrainian SSR and Tomsk District of the RSFSR are given. It has been shown that in the Ukrain over 1/3 of all populations of the specific intermediate host of opisthorchis does not take part in the circulation of the agent due to fundamentally different reasons: resistence to the infection and hyperinfection with parthenites of trematodes.
