dc.description.resumoIn 2012 a malacological survey of the breeding sites of Biomphalaria glabrataand B. straminea, the two intermediate host snails of Schistosoma mansoni, was carried out on Itamaraca Island in Pernambuco, Brazil. This study has nowbeen extended by studying the competition between the two species. Snails were collected and dissected to identify the speciesand tests were performed to verify S. mansoniinfection. Student’s ttest was used to compare the proportion between the twospecies and their breeding sites and a parasitological survey was conducted among local residents, using the Kato-Katzmethod. The spatial distribution of the two snail species was determined using TerraView, while a snail density map was constructed by Kernel estimate. The survey identified two breeding sites for B. glabratawith 17 specimens and 19 breeding sitesfor B. stramineawith 459 snails, all of them negative for S. mansoni infection. The statistical analysis revealed that the proportion of the numbers of specimens and breeding sites of B. straminea (37.84 ± 9.01) were significantly greater than thoseof B. glabrata(8.50 ± 6.50). Parasitological examinations from 41 residents diagnosed two cases of schistosomiasis with parasite loads of 60 and 84 eggs per 1 g of stool, respectively. This indiction of a competitive process between the two snail speciesrequires monitoring of schistosomiasis in the resident and travelling human populations occupying this environment, whichcould potentially result in social and economic changes on the island risking its attraction as a centre for eco-tourism.pt_BR
