[The water-cress pools in connection with cases of human fasciolasis in Limousin, France. Experimental studies of Trematode snails and their biological control (author's transl)].
Experimental studies on 16 water-cress pools with cases of human fasciolasis in Limousin were undertaken. Two species of snails, Lymnaea glabra and L. truncatula are here trematode hosts. L. glabra alone lives in 5 pools. The introduction of Zonitoides nitidus -- predatory snail -- without vegetation modification produces a progressive elimination of Lymnaea in 3 years. The author insists on the use of determine the trematode host-aptitude of L. glabra and its limits when the two species -- L. glabra and L. truncatula -- live in the same habitats.
