Modelling climate change impact on the spatial distribution of fresh water snails hosting trematodes in Zimbabwe

Parasites & Vectors, 2014
BackgroundFreshwater snails are intermediate hosts for a number of trematodes of which some are of medical and veterinary importance. The trematodes rely on specific species of snails to complete their life cycle; hence the ecology of the snails is a key
