longitudinal study on the natural infection of biomphalaria straminea and b. glabrata by schistosoma mansoni in an endemic area of schistosomiasis in pernambuco, brazil.	the abundance of snail hosts and the rates of infection with schistosoma mansoni were monitored monthly for four years in two representative localities subjected to repeated chemotherapy of infected persons. snail abundance varied from 1.0 to 4.4 collected per person/minute/station for biomphalaria straminea and from 0.1 to 7.0 for b. glabrata. infection rates of snails in nature varied from 0% to 15% for the former and from 0% to 70% for the latter species. human infection increased from 35.5% ...	2002	12118274
