Myxozoa Grass?, 1970 (Cnidaria: Myxosporea): Sinopse das esp?cies parasitando peixes nas Am?ricas e diagn?stico morfol?gico e molecular das esp?cies parasitando Characiformes, Leporinus friderici (Anostomidae) e Astyanax altiparanae (Characidae) oriundos do rio Mogi Gua??, S?o Paulo, Brasil / Myxozoa Grass?, 1970 (Cnidaria: Myxosporea): Synopsis of species parasiating fish in the Americas and morphological and molecular diagnosis of species parasiating Characiformes species, Leporinus friderici (Anostomidae) and Astyanax altiparanae (Characidae) from the Mogi Gua??

No. of bitstreams: 1 2017 - Let?cia Gabriela Poblete Vidal.pdf: 2525390 bytes, checksum: 162c0cfed2f6b4d8e94cb85c1c0254da (MD5) Previous issue date: 2017-03-08 / CNPq / 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 Grass?, 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 (?m 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 Gua?? River, state of S?o 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. / O presente trabalho teve como objetivo ampliar os conhecimentos sobre a biodiversidade de mixospor?deos parasitos de peixes, visto o escasso conhecimento para esse grupo. No cap?tulo 1 o objetivo foi fornecer uma sinopse de esp?cies de Myxozoa Grass?, 1970 nas Am?ricas com base em um levantamento bibliogr?fico desde 1893, quando a primeira esp?cie de myxospor?deo foi descrita, at? dezembro de 2015. A sinopse inclui uma lista parasito-hospedeiro com dados sobre o habitat do hospedeiro, s?tio de infec??o, localidade, tamanho e formato do cisto, medidas dos esporos e esp?cimes em cole??es e uma lista de parasitos-hospedeiros. Nessa sinopse s?o relatados somente as descri??es originais encontradas nas Am?ricas. No cap?tulo 2, ? inclu?da uma descri??o de H. friderici Casal, Matos e Azevedo, 2003 com novos dados morfol?gicos e moleculares com material proveniente de amostras de filamentos branquiais de Leporinus friderici (Bloch, 1794) do rio Mogi Gua??, estado de S?o Paulo. Finalmente, no cap?tulo 3, uma esp?cie de Henneguya encontrada nos rins de Astyanax altiparanae (Characiformes: Characidae) foi descrita e ilustrada com base na sua morfologia e na an?lise do rDNA da subunidade maior do ribossomo (28S). Estes dados identificam uma poss?vel esp?cie nova de Myxozoa.
