Fasciola immature stages sought in Lymnaea species and Biomphalaria species in the water bodies of Dakahlia Governorate.

Examination of the five different water bodies in Dakahlia governorate, revealed four species of Lymnaea. These were L. natalensis (68.4%). L. truncatula (16%), L. stagnalis (12.2%) and L. columella (3.4%). Also, two species of Biomphalaria were recovered. These were B. alexandrina (54.7%) and B. glabrata (45.3%). Examination of all these snails showed natural infection with immature stages of Fasciola sp. in 5.5% of L. natalensis (= cailliaudi), 3.1% in L. truncatula and 0.67% in B. alexandrina. The importance of these snails in dissemination and spreading of fascioliasis was discussed.
