Myxozoa Grassé, 1970 (Cnidaria: Myxosporea): sinopse das espécies parasitando peixes nas Américas e diagnóstico morfológico e molecular das espécies parasitando Characiformes, Leporinus friderici (Anostomidae) e Astyanax altiparanae (Characidae) oriundos do rio Mogi Guaçú, São Paulo, Brasil

Abstract

The hope of this study was increased the knowledge of biodiversity of myxozoan fish parasites, unknown to some groups. In chapter 1, the goal was provide a synopsis of Myxozoa Grassé, 1970 species in the Americas based on records of the valid species of myxozoans (Myxozoa: Myxosporea) described in the Americas is provided based on a comprehensive survey of the literature since 1893, when the first myxozoan species was reported, until December 2015. The synopsis include the habitat of the host, site of the infection of the parasite, locality, size (µm or mm) and form of the plasmodia, spore measurements, provide specimens to parasitological collections, molecular data and explicit linkage of host. This synopsis was based on original descriptions. In chapter 2, the present work complements the original description of H. friderici Casal Matos and Azevedo, 2003 with new morphological and molecular data with Gill filaments on Leporinus friderici (Bloch, 1794) from the Mogi Guaçú River, state of São Paulo. Finaly, in chapter 3, specie of Henneguya was found in the kidneys of Astyanax altiparanae (Characiformes: Characidae) and were analyzed by morphological and molecular studies with analysis of the rDNA of the small subunid of the ribosome (18S). These data identify a new species of Myxozoa.
