[experimental schistosomiases. i. study of s. mansoni fecondity as regards to its adaptation to different biomphalaria glabrata strains (author's transl)].	we compared the infestation of different strains of b. glabrata from brasil (recife). guadeloupe, martinique and porto-rico with 6 to 8 miracidia of s. mansoni (from recife. we noted the four following points: 1. the planorbid snails from martinique and guadeloupe had a low resistance to infestation. 2. the guadeloupean snails showed the lesser rate of positivity and the lower medium amount of emitted cercaries but, in the four strains of snails, the level of the issued cercaries is quite the sa ...	1975	1221915
intermediate hosts of schistosoma mansoni in brazil.	the brazilian planorbidical chart is slowly but progressively been increased by new data. distribution of vector species of schistosoma mansoni, according to paraense, 1986, may be thus resumed: biomphalaria glabrata--delimited by parallels 13 and 21 degrees s and meridians 39 and 45 degrees w, area of greater dominance (southeast bahia, oriental hal of minas gerais and espírito santo). it is observed along the coast line of the states of sergipe, alagoas, pernambuco, paraiba and rio grande do n ...	1992	1343914
[ecoepidemiology of urban schistosomiasis in itamaracá island, pernambuco, brazil].	in 1988, 22 autochthonous cases from accidental exposure were registered in forte orange beach, itamaracá island, pernambuco, brazil. all cases occurred in middle-to-upper class individuals who were vacationing in the island. after the cases were identified, the major objective was to find breeding sites of schistosomiasis vectors and correlate the biological factors with the environmental conditions.	2000	10973151
molecular identification of symbionts from the pulmonate snail biomphalaria glabrata in brazil.	the icthyosporean, capsaspora owczarzaki, a known predator of schistosoma mansoni sporocysts in vitro, is more prevalent in laboratory-reared strains of the intermediate snail host, biomphalaria glabrata resistant to s. mansoni, than from the susceptible m line strain. we examined whether b. glabrata resistant to the nih-pr-1 strain of s. mansoni from 2 regions in brazil were also host to c. owczarzaki. symbiont presence was examined using hemolymph culturing and nested polymerase chain reaction ...	2004	15357065
spatial distribution of schistosomiasis foci on itamaracá island, pernambuco, brazil.	acute cases of schistosomiasis have been found on the coastal area of pernambuco, brazil, due to environmental disturbances and disorderly occupation of the urban areas. this study identifies and spatially marks the main foci of the snail host species, biomphalaria glabrata on itamaracá island. the chaotic occupation of the beach resorts has favoured the emergence of transmission foci, thus exposing residents and tourists to the risk of infection. a database covering five years of epidemiologica ...	2004	15486640
[spatial analysis of biomphalaria glabrata foci and human cases of mansoni schistosomiasis in porto de galinhas, pernambuco state, brazil, in the year 2000].	this article provides information on the spatial distribution of schistosomiasis, correlating snail foci with human cases using spatial analysis. the locations studied were merepe iii, pantanal, salinas, and socó, comprising 70% of the populated area of porto de galinhas. malacological and parasitological surveys by a cpqam/ fiocruz team at the location where an epidemic occurred in 2000 identified 15 foci of infected b. glabrata. human cases were also diagnosed and recorded according to residen ...	2007	17221090
[temporary and permanent breeding sites for biomphalaria in jaboatão dos guararapes, pe].	a malacological survey of permanent and temporary breeding sites was conducted in the piedade neighborhood of jaboatão dos guararapes, pernambuco, between november 2006 and november 2007, with the aim of determining the malacological fauna at this locality, along with the potential for schistosomiasis mansoni transmission. in addition to biomphalaria glabrata (say, 1818), the molluscs drepanotrema cimex (moricand, 1837), pomacea sp and melanoides tuberculatus (muller, 1774) were collected. among ...	2008	18719804
