| [susceptibility of biomphalaria tenagophila from the paraná and uruguay river basins to schistosoma mansoni]. | to study the possibility that schistosomiasis might be able to spread into the basins of the paraná and uruguay rivers, 1,711 snails were experimentally exposed to infection with schistosoma mansoni. these snails were laboratory-bred progeny of biomphalaria tenagophila collected from 15 populations in the geographic area under consideration. three strains of s. mansoni were used: bh2, adapted to b. glabrata, and sj and sj2 adapted to b. tenagophila. none of the 543 snails exposed to the bh2 stra ... | 1997 | 9162585 |
| intermediate and definitive hosts of schistosoma mansoni in corrientes province, argentina. | corrientes province is located in the humid subtropical region of argentina northeast on the left riverbank of paraná river in the border with the south of brazil. this is a region without schistosomiasis but planorbid and rodents that would serve as host of the life cycle of schistosoma mansoni inhabit here. the objective of this work is to know the role of rodent as definitive host of schistosomiasis. biomphalaria tenagophila (4 to 8 mm ø) from maloyas, exposed each to 10 miracidia of sj2 stra ... | 2006 | 17308774 |
| biomphalaria tenagophila potencial vector of schistosoma mansoni in the paraná river basin (argentina and paraguay). | susceptibility and compatibility experiments were carried out with 700 biomphalaria tenagophila from the paraná river basin exposed to infection with schistosoma mansoni. individual infection was performed with 10 miracidia of sj2 strain from the paraiba valley (brazil) originally infective to b. tenagophila. these snails were laboratory-breed progeny of b. tenagophila collected from six localities of argentina and one from paraguay. from argentina: rincón de vences (7%) and posadas (11%) became ... | 2007 | 17426884 |
