SOUZA, Marco A. A.  and  MELO, Alan L.. Characterization of larval trematodes emerging from gastropod mollusks collected in Mariana, Minas Gerais, Brazil. Iheringia, Sér. Zool. [online]. 2012, vol.102, n.1, pp. 11-18. ISSN 0073-4721.  http://dx.doi.org/10.1590/S0073-47212012000100002.

In malacological survey conducted at Mariana municipality, state of Minas Gerais, Brazil, between April 2003 and February 2004 were found Biomphalaria glabrata (Say, 1818) and Physa marmorata Guilding, 1828 mollusks harboring Digenea larval trematodes. In B. glabrata were observed, in addition to cercaria of Schistosoma mansoni Sambon, 1907, strigeocercaria, two types of xiphidiocercaria, ocellifera cercaria and two types of gymnocephalus, while in P. marmorata the only larval form emerging was echinostome cercaria. Some of cercariae found differ from those described in the literature.
