title: Molecular studies of Biomphalaria glabrata, an intermediate host of Schistosoma mansoni.
abstract: The freshwater gastropod Biomphalaria glabrata is one of the most important invertebrate hosts of the helminth parasite Schistosoma mansoni. Investigators are using different strategies to determine the molecular basis of this snail-parasite relationship. Of particular interest are the identification of parasite resistance genes in the snail, and the application of molecular probes to better understand the epidemiology of schistosomiasis. This review will focus on recent advances that have been made on genome analysis of B. glabrata. Much of this work has centred on the use of random amplification of polymorphic DNA-PCR-based technology, with restriction fragment length polymorphism analysis and the generation of expressed sequence tags from the snail. A brief discussion of how parasite products may complicate this analysis is also given, along with an indication of the scope of the problems that lie ahead.
