Chaetogaster limnaei K von Baer 1872 on Lymnaea tomentosa: ingestion of Fasciola hepatica cercariae.
The fresh water mollusc, Lymnaea tomentosa, the intermediate host of the liver fluke is heavily infested under natural conditions with ectocommensal annelid, Chaetogaster limnaei. These annelids which destroy the larval stages of Fasciola hepatica have been observed in the laboratory. The association of C. limnaei with the snail intermediate host is of value in exploiting a control measure against economically important liver fluke disease.
