Myxozoa parasitos de Pseudoplatystoma corruscans (pintado), Salminus franciscanus (dourado) e Brycon orthotaenia (matrinxã) oriundos da bacia do rio São Francisco, MG: Myxozoa parasites of Pseudoplatystoma corruscans (pintado), Salminus franciscanus (dourado) and Brycon orthotaenia (matrinxã) from the São Francisco river basin, MG.

Degree: 2014, Universidade Estadual de Campinas

Abstract: Myxosporeans are cosmopolitan parasites and infect fish in various regions of the world. So far, are known about 2,400 species, of which the vast majority are parasites of fishes, from natural environment and fish farms, and some species responsible for high mortality rates in various parts of the world. This work aimed to study the diversity of myxosporeans of Pseudoplatystoma corruscans (pintado), Salminus franciscanus (dourado) and Brycon orthotaenia (matrinxã) from the São Francisco River, municipality of Pirapora, MG, Brazil. Morphological, ultrastructural, histological and molecular studies of five new species of myxosporeans were performed, being one species of the genus Henneguya infecting pintado, two of the genus Myxobolus infecting dourado and two infecting matrinxã. Henneguya sp. n. 1 had white and elongated plasmodia in the connective tissue of the gill filaments. The ultrastructural analysis revealed the plasmodial wall with delicate projections towards the tissues of the host, and the presence of a thin layer of fibrous material isolating the parasite of the contact with the host tissue. Histological analysis revealed that the development of the plasmodium caused compression of the connective and epithelial tissue, deformation of the filament and lamellar fusion. Phylogenetic analysis, based on 18S rDNA gene, and using only Henneguya and Myxobolus parasites of siluriformes revealed clustering according to the family of the host fish. Myxobolus sp. n. 1 had white and rounded plasmodia that developed between the fin rays of dourado. The ultrastructural analysis showed a fibroblast layer surrounding the plasmodium, preventing contact of the parasite with the host tissues. Myxobolus sp. n. 2 had white and rounded plasmodia that developed in the liver also of dourado. Myxobolus sp. n. 3 and Myxobolus sp. n. 4 infected matrinxã, being that the first had white and rounded plasmodia in the spleen and the second in the kidney. The ultrastructural analyses of Myxobolus sp. n. 2, Myxobolus sp. n. 3 and Myxobolus sp. n. 4 revealed direct contact between the plasmodial wall and the host tissue. The plasmodial wall of the five myxosporeans species subject of this study was composed by single membrane. The process of sporogenesis in these five species was asynchronous, with germ cells and young development stages of spores occurring in the periphery of the plasmodia and immature and mature spores in the central region. Phylogenetic analysis based on 18S rDNA gene and using only Henneguya and Myxobolus parasites of fish from South America plus the four new Myxobolus species parasites of bryconids, shows host specificity and organs/tissue affinity as important evolutionary signs to Myxobolus/Henneguya Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Adriano, Edson Aparecido (advisor), Universidade Estadual de Campinas.

Mixosporídeos em oligoquetas (actinosporos) e em peixes (mixosporos) de pisciculturas dos estados de São Paulo e Mato Grosso do Sul, Brasil: Myxosporean in oligochaetes (actinospores) and fish (mixospores) from fish farms in the states of São Paulo and Mato Grosso do Sul, Brazil.

Degree: 2015, Universidade Estadual de Campinas

Abstract: Among the fish parasites, those of the Myxozoa phylum are highlighted as the most important. Most species of myxozoans show life cycle that involves two development stages, being that in vertebrates, mainly in annelids, occurs the actinospore stage and in vertebrates, mainly in fishes, but also in amphibians, reptiles, birds and mammals, the myxospore stage. In this study, morphological and molecular analysis were performed in actinospore and myxospore stages found in oligochaetes and fishes from fish farms from São Paulo and Mato Grosso do Sul states. For the actinosporo study, were performed two oligochaetes gatherings in two fish farms, one located in municipality of Porto Ferreira, São Paulo state and other in municipality of Terenos, Mato Grosso do Sul state. Of the 333 oligochaetes collected in Porto Ferreira, 13 (3.9%) specimen of Pristina americana were observed releasing four actinospore types, being Aurantiactinomyxon types 1, 2 and 3, and Helioactinomyxon type 1. The ultrastructural analysis performed in one specimen of P. americana showed two different developmental stages of pansporocysts of Aurantiactinomyxon type 2 in the gut wall. In Terenos, 86 specimens of oligochaetes were collected, being that one specimen (0.9%) identified as Slavina evelinae was releasing actinospore of Seisactinomyxon type 1 nov., which belongs to collective group still not reported in the literature. The oligochaetes identification was performed based on morphological data and on the 18S rDNA sequencing. The sequencing of the 18S rDNA of Aurantiactinomyxon types 1 and 2, and Seisactinomyxon type 1 nov. were also performed, resulting in partial sequences containing 1200, 902 and 1877pb, respectively. The phylogenetic analysis showed that Aurantiactinomyxon type 1 and 2, and Seisactinomyxon type 1 nov. have grouped in a clade with a Thelohanellus species parasite of Siluriformes and other six species of Myxobolus parasites of Characiforms fishes. In the mixospore study, specimens of patinga (hybrid resulted from a cross between Piaractus mesopotamicus and P. brachypomus) and pintado (hybrid resulted from a cross between Pseudoplatystoma corruscans and P. reticulatum), were gathered from two fish farms in São Paulo state. From 15 specimens of patinga collected in Porto Ferreira, 11 (73.3%) presented Myxobolus cf. cuneus infection, and from the 20 specimens of hybrid pintado collected in Mogi Mirim, eight (40%) showed Henneguya pseudoplatystoma infection. The 18S rDNA sequencing of M. cf. cuneus and H. pseudoplatystoma spores resulted in sequences containing 1855 and 1946 bp, respectively. The M. cf. cuneus ultrastructural analysis revealed that the plasmodium presented an asynchronous development, with the presence of disporic pansporoblasts in two different development phase, and immature and mature spores in the whole plasmodium. The phylogenetic analysis showed M. cf cuneus as a sister specie of H. pellucida, in a subclade mainly composed of myxozoans parasites of Characiforms and H. pseudoplatystoma grouped in a… Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Adriano, Edson Aparecido (advisor), Universidade Estadual de Campinas.

Degree: 2009, Universidade Estadual de Campinas

Abstract: The ultrastructure of bivalve spermatozoa can be species-specific and often provide valuable taxonomic traits for systematic reviews and phylogenetic reconstructions. Transmission and scanning electron microscopy was an efficient tool to differentiate the spermatozoan structure of species sharing many conchological characters, which could lead to equivocal identification. We analyzed sperm ultrastructural features that were useful for taxonomic issues with regard to Isognomon bicolor and Isognomon alatus (Isognomonidae); Macoma constricta, Macoma biota and Tellina lineata (Tellinidae); Donax hanleyanus and Donax gemmula (Donacidae). The data revealed that the bivalve species studied here, except T. lineata, produce primitive-type spermatozoa, typical of marine invertebrates in which eggs are fertilized in the surrounding water. We, also, compared the ultrastructure of spermatozoa from the bivalves Anomalocardia brasiliana and Tivela mactroides (Veneridae). The spermatozoa of both species contain a curved nucleus with a short cone-shaped acrosome. There were six mitochondria and glycogen clusters in the middle piece of the T. mactroides sperm cell. Possibly, the glycogen clusters and the higher mitochondria number correspond to an adaptive advantage in turbulent waters. Increasing the sperm life expectance also increases the odds of finding the eggs and accomplishing fertilization. Oysters of the genus Crassostrea and mussels of the genus Mytella, commercially important in Brazil, were also investigated in this thesis. The sperm ultrastructure of the specimens described herein and molecular studies, confirm the presence of Crassostrea brasiliana (Ostreidae) in Cananéia. Spermatozoa of mussel specimens of the genus Mytella, from two populations living in distinct habitats (muddy-sand sediment and rocky shores), were examined by transmission electron microscopy. The spermatozoa of all specimens shared the same ultrastructural pattern suggesting that the analyzed specimens, which live in distinct habitats, indeed belong to a same species, which was identified as M. charruana (Mytilidae) based on conchological analysis. The presence of an axial rod in sperm cells upholds the inclusion of M. charruana in the subfamily Mytilinae. In conclusion the electron microscopy was an efficient method to solve some particular taxonomic issues. The present spermatozoan ultrastructural studies have provided new and welcome data about the families Isognomonidae, Veneridae, Tellinidae, Donacidae, Ostreidae and Mytilidae. The results showed in this thesis could be valuable in future phylogenetic analyses.
