Snail vector of trematode
This document summarizes the different families of snails that act as vectors for trematode parasites, including the specific snail-trematode relationships. It begins with an introduction stating that trematodes have significant economic impacts in developing countries. It then provides tables listing the main snail families (Planorbidae, Lymnaeidae, Ancylidae, Physidae, Hydrobiidae, Thiaridae, Viviparidae, Pilidae), along with the specific snail genera within each family. For each snail genus, it names the trematode(s) that snail serves as a vector for. The document concludes by thanking the audience and listing references used.

- 3. Introduction Trematodes are ofextreme economic importance, specially in tropical developing countries. There is very considerable economic loss in the form of mortality, reduced weight gain, decreased production, low fertility, reduction in draft power and poor hide quality in Bangladesh due to parasitic diseases. Different species of vector snails carry larval stage of different Trematode belonging to the superfamilies Schistosomatoidea, Fascioloidea, Paramphistomoidea, Ehinostomatoidea, Diplostomoidea and Pronocephaloidea.
