Establishment of a Gene Pool Strain of Schistosoma mansoni

A Gene-pool line of Schistosoma mansoni was established after allowing four isolates of S. mansoni from Brazil, Egypt and Puerto Rico and Kenya. The infectivity test of these four parental isolates in three Biomphalaria glabrata isolates from Brazil, Puerto Rico and Egypt gave > 90% infection rates. The infectivity test of newly established parasite (now called Sm-Gp (Schistosoma mansoni gene pool)) gave par-higher rates of infection when compared with parental parasite isolates.
