SOUZA, Marco A. A. et al. Ecological aspects and malacological survey to identification of transmission risk' sites for schistosomiasis in Pernambuco North Coast, Brazil. Iheringia, Sér. Zool. [online]. 2010, vol.100, n.1, pp.19-24. ISSN 0073-4721.

It was carried out a malacological survey at Carne de Vaca beach, Goiana municipality, Pernambuco North coast, between November 2006 and October 2007 in order to know the malacological fauna of this town and verify the natural, slightly or more modified conditions of mollusks sites by using an habitat diversity protocol analysis. From 5,912 mollusks collected, they belong to seven species and four families, as follows: 5,209 Biomphalaria glabrata (Say, 1818) specimens, 113 of Drepanotrema lucidum (Pfeiffer, 1839), 55 of Drepanotrema cimex (Moricand, 1837), 13 of Drepanotrema anatinum (Pfeiffer, 1839), 222 of Melanoides tuberculatus (Muller, 1774), 263 of Pomacea sp. and 37 of Physa marmorata Guilding, 1828. Among B. glabrata collected, 44 specimens were positive for Schistosoma mansoni Sambon, 1907 cercariae and 91 specimens were positive for other trematode larvae. One Pomacea sp. specimen was positive for trematode larvae. These data, spatially georeferenced, will be used for determination of risk' sites for schistosomiasis transmission at Carne de Vaca beach and furthermore, they will be used for computational simulations to determine the expansion process of schistosomiasis in state of Pernambuco.
