study of a population of biomphalaria tenagophila (orbigny, 1835) and of schistosomiasis transmission in "alto da boa vista", rio de janeiro.	the present study was performed using data from a biomphalaria tenagophila population located in a watercress garden in the alto da boa vista region representing an isolated focal point of schistosomiasis in the city of rio de janeiro. the density and age structure of this b. tenagophila population and its rate of infection by schistosoma mansoni were studied for a period of 15 months. the snail population showed seasonal variation in density, with a decrease in number of individuals at the begi ...	1989	2520827
factors conditioning the habitat and the density of biomphalaria tenagophila (orbigny, 1835) in an isolated schistosomiasis focus in rio de janeiro city.	the present work was carried out in a watercress garden in alto da boa vista, in the city of rio de janeiro, brazil. the investigation was carried out in two phases. the first one (1985-86) involved the sampling of biomphalaria tenegophila in two areas to determine its relative populational densities. the results showed that the populations presented similar densities and dynamics. the second phase (1988-89) involved the study of the influence of some environmental factors on the establishment o ...	1993	8107608
