| [host parasite relationship among 3 schistosoma mansoni and 6 biomphalaria glabrata strains from epidemic and no epidemic venezuelan areas is studied]. | six lots of 18 b. glabrata from: la victoria, turmero, cagua in aragua state; caserío el 25 in carabobo state, chabasquén in portuguesa state and humocaro bajo in lara state, were experimentally infected with miracidia of sm, c5 and c6 strains of schistosoma mansoni (18 snails/schistosoma mansoni strain). the averages of the intramolluscal period (imp) obtained for the s. mansoni strains were very similar and comprised between 35.4 and 36.1 days. no significative statistical differences in the i ... | 2000 | 11338975 |
| [compatibility between nine strains of biomphalaria glabrata coming from endemic and non-endemic areas and one strain of schistosoma mansoni from venezuela]. | nine lots of 32 b. glabrata snails (5-7mm in diameter) from the following strains from the endemic area: cagua, valencia lake (puerta negra sector), ingenio bolívar (aragua state), mariara, caserío el 25 and güigüe (carabobo state), and from the non-endemic area: anzoátegui (lara state), chabasquén (portuguesa state) and caripe (monagas state) were experimentally infected (5 miracidiums/snail) with c5 schistosoma mansoni strain. the intramolluscal prepatent period oscillated between 23 and 25 da ... | 1999 | 10881105 |
