Prospects for the control of opisthorchis infection by the sanitation of the mollusk population

Prospects for the control of opisthorchis infection by the sanitation of the mollusk population

Sanitation of the mollusk population with highly effective cercaricide preparations can be used for control of Opisthorchis infection. Low concentrations of molluscicides which are sublethal for non-infected mollusks are lethal for hyperinfected individuals. All tested molluscicides display a cercaricide effect in concentrations which are considerably lower than molluscicide ones. Low concentrations of cercaricides are toxic for cercariae and parthenites from the liver of mollusks and for freely swimming cercariae. Destroying free swimming cercariae prevents infection of a 2nd intermediate host. Microdoses of cercaricides which are lethal for cercariae are not toxic for the majority of hydrobionts including fishes. The infection level of Bithynia with O. felineus is characterized by 1 distinct peak in the middle-end of July; the treatment of water bodies with microdoses of cercaricides should be carried out in this period.
