Resumo: | CHAPTER I - The National Park Serra da Capivara, Piau? state, Brazil, presents an extraordinary scenario for improvement of the studies of helminth biodiversity. The Park has diversity mammals? species among them marsupials and armadillos are frequently seen and occasionally found dead by running over on the road. Three specimens of opossum Didelphis albiventris and two of armadillo Dasypus novemcinctus were found dead in the Park and their viscera were donated by Funda??o Museu do Homem Americano (FUMDHAM) to be studied in Instituto Oswaldo Cruz. Helminths collected in intestine were fixed in alcohol 70% or formal 4%. Parasites were clarified in glycerin for studies in microscopy of light. Some specimens were post-fixed in 1% OsO4 and potassium ferrocyanide 0.8%, dehydrated in alcoholic series, and conducted to critical point with CO2 coated with gold and visualized through scanning electron microscopy. Genomic DNA of the parasites was extracted using QIAmp DNA Mini Kit, and two set of primers were designed to polymerase chain reaction and amplicons sequenced. The species found were Aspidodera raillieti, and A. subulata from Didelphis albiventris and A. binansata, A. vazi and Hadrostrongylus speciosum from Dasypus novemcinctus from the Serra da Capivara National Park, Piau? State, Brazil were studied herein. New ultrastructural data of A. binansata and A. vazi were obtained. Sequences of cytochrome c-oxidase subunit 1 of mitochondrial DNA (mtDNA cox-1), partial mitochondrial 16S rDNA (rnnL), new sequence of partial 18S rDNA (SSU), internal transcriber spacers (ITS) 1, and 2 and 5.8S rDNA gene, and new sequence of partial 28S rDNA (LSU) gene of A. raillieti are presented. Genetic data includes the first sequence of SSU and LSU for A. raillieti and first LSU gene for Aspidoderidae. Additionally, first sequence of 16S rDNA of A. vazi was obtained. Phylogenetic analysis of maximum-likelihood using LSU gene showed Heterakoidea (represented by Aspidoderidae and Heterakidae) compose clade strongly supported (100%) and considered sister-group of Cosmocercoidea, represented by Rondonia rondonia and Orientatractis moraveci (Atractidae). Ramsonnematoidea, Rhigonematoidea and other Cosmocercoidea represented by Cosmocercoides pulcher and C. tonkinensis (Cosmocercidae) appear in a separeted clade with high statistical support. Cosmocercoidea is considered a paraphyletic group. New ultrastructural, genetic and of geographical distribution are presented and discussed. =========== CHAPTER II - The diagnosis of helminth eggs is routinely performed in the areas of human and veterinary parasitology as it provides a quick and low cost result for the treatment of parasitic diseases. In the Serra da Capivara National Park (PNSC), Piau?, Brazil, archaeological sites have revealed helminth eggs obtained in coprolites dating back thousands of years. Specific identification of eggs is difficult without the adult parasites being properly identified. The objective of this work was to study the biodiversity of helminth eggs of wild mammals from the PNSC, after identification of adult parasites. Seven species of wild mammals from a total of 16 specimens found dead were examined: deer, wild pig, agouti, ocelot, dog-eating fox, opossum and armadillo. The parasites collected from the gastrointestinal contents were identified by morphology and genetics. The eggs obtained from female adults were measured and photographed. A total of 12 species of helminth and their eggs were found, being 1 Acanthocephala and 11 Nematoda species. In the phylum Acanthocephala, Oncicola venezuelensis was found and among the Nematoda, four species of Aspidoderidae (Aspidodera raillieti, A. subulata, A. binansata and A. vazi), two Trichonstrongyloidea (Haemonchus sp. and Trichostrongylus colubriformis), two Molineidae (Molineus sp. and Hadrostrongylus speciosum), a Toxocaridae (Toxocara canis) and two Nematoda gen. sp. unidentified were reported. Our data compared with the eggs obtained from fresh faeces corroborate the presence of Aspidoderidae and Trichostrongyloidea members in wild mammals in the park area. When compared to eggs obtained in coprolites, the genera Toxocara and Oncicola appear in the ancestral and current fauna of carnivores, and is likely that species within this genus may be keeping their lifecycles for millennia in the park. In addition, an identification key to the species found in this study was designed to serve as an aid in the diagnosis of species. These data become important because they can serve as a comparative basis for the studies of current and ancestral fauna of helminths occurring in the park. |

Possui uma fauna de mam?feros diversificada incluindo os marsupiais e tatus que s?o frequentemente vistos e, ocasionalmente, encontrados atropelados nas rodovias perif?ricas. Tr?s esp?cimes de gamb?s Didelphis albiventris e dois de tatus Dasypus novemcinctus foram encontrados mortos na ?rea do parque e suas v?sceras foram doadas pela Funda??o Museu do Homem Americano (FUMDHAM) para serem estudados no Instituto Oswaldo Cruz - RJ. Os helmintos coletados do intestino foram fixados em ?lcool 70% ou formol 4%. Foram clarificados em glicerina para estudos por microscopia de luz e alguns esp?cimes foram p?s-fixados em 1% OsO4 e ferrocianeto de pot?ssio 0,8%, desidratados em s?rie alco?lica, levados ao ponto cr?tico com CO2, revestidos com ouro e examinados atrav?s da microscopia eletr?nica de varredura. O DNA gen?mico dos parasitos foi extra?do utilizando QIAamp DNA Mini Kit. Dois pares de primers foram desenhados para rea??o da cadeia da polimerase e em seguida o material foi sequenciado. As esp?cies encontradas foram: Aspidodera raillieti e A. subulata parasitos intestinais do gamb?-de-orelha-branca e A. binansata, A. vazi e Hadrostrongylus speciosum parasitos do tatu Dasypus novemcinctus. Novos dados ultraestruturais de A. binansata e A. vazi foram obtidos. Sequ?ncias do citocromo c-oxidase da subunidade 1 do DNA mitocondrial (mtDNA cox1), da regi?o parcial 16S rDNA (rnnL), nova sequ?ncia parcial do gene 18S rDNA (SSU), espa?adores transcritos internos (ITS) 1 e 2 e o gene 5.8S rDNA, al?m de nova sequ?ncia parcial do gene 28S rDNA (LSU) de A. raillieti s?o apresentados. Os dados gen?ticos incluem a primeira sequ?ncia de SSU e LSU para A. raillieti e primeiro gene LSU para Aspidoderidae. Al?m disso, foi obtida a primeira sequ?ncia de A. vazi do gene parcial 16S rDNA. A an?lise filogen?tica da m?xima-verossimilhan?a utilizando o gene LSU rDNA mostrou que Heterakoidea, representado por Aspidoderidae e Heterakidae, comp?e um clado com alto suporte estat?stico, considerado grupo irm?o de Cosmocercoidea representado por Rondonia rondonia e Orientatractis moraveci (Atractidae). Ransomnematoidea, Rhigonematoidea e outros Cosmocercoidea representados por Cosmocercoides pulcher e C. tonkinensis (Cosmocercidae) formam um clado separado com alto suporte estat?stico. Cosmocercoidea ? considerado um grupo parafil?tico. Novos dados ultraestruturais, gen?ticos e de distribui??o geogr?fica s?o apresentados e discutidos. ======================= CAP?TULO II - O diagn?stico de ovos de helmintos ? realizado rotineiramente nas ?reas de parasitologia veterin?ria e humana, pois fornece um exame r?pido e de baixo custo para o tratamento das parasitoses. No Parque Nacional Serra da Capivara (PNSC), Piau?, Brasil, os s?tios arqueol?gicos t?m revelado ovos de helmintos obtidos em copr?litos que datam de milhares de anos. A identifica??o espec?fica dos ovos ? dif?cil sem que os parasitos adultos sejam devidamente identificados. O objetivo deste trabalho foi estudar a biodiversidade de ovos de helmintos de mam?feros silvestres do PNSC ap?s a identifica??o dos parasitos adultos. Sete esp?cies de mam?feros silvestres de um total de 16 esp?cimes encontrados mortos foram examinados: Veado-catigueiro, Porco-selvagem, Cutia, Jaguatirica, Cachorro-do-mato, Gamb? e Tatu-verdadeiro. Os parasitos coletados do conte?do gastrointestinal foram identificados por morfologia e gen?tica. Os ovos obtidos a partir de f?meas adultas foram medidos e fotografados. Um total de doze esp?cies de helmintos com ovos foram encontrados, sendo uma esp?cie de Acanthocephala e 11 esp?cies de Nematoda. No filo Acanthocephala foi encontrado Oncicola venezuelensis e dentre os Nematoda, quatro esp?cies de Aspidoderidae (Aspidodera raillieti, A. subulata, A. binansata e A. vazi), dois Trichonstrongyloidea (Haemonchus sp. e Trichostrongylus colubriformis), dois Molineidae (Molineus sp. e Hadrostrongylus speciosum), um Toxocaridae (Toxocara canis) e ainda mais dois Nematoda gen. sp. n?o identificado foram notificados. Nossos dados quando comparados com os ovos obtidos em fezes recentes corroboram com a presen?a de membros de Aspidoderidae e Trichostrongyloidea em mam?feros silvestres na regi?o do parque. Quando comparados com ovos obtidos em copr?litos, os g?neros Toxocara e Oncicola, aparecem na fauna ancestral e atual de carn?voros, e ? prov?vel que esp?cies dentro deste g?nero possam estar mantendo seus ciclos de vida h? mil?nios no parque. Adicionalmente, uma chave de identifica??o para as esp?cies encontradas neste estudo foi elaborada para servir de aux?lio no diagn?stico das esp?cies. Estes dados tornam-se importantes porque podem servir de base comparativa para os estudos com fauna de helmintos atual e ancestral realizados no parque.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2019-06-24T18:09:55Z No. of bitstreams: 1 2016 - Everton Gustavo Nunes dos Santos.pdf: 18116066 bytes, checksum: 046d9b3338c35cef8f793d5fa0adb8cb (MD5)Made available in DSpace on 2019-06-24T18:09:55Z (GMT).

CHAPTER I - The National Park Serra da Capivara, Piau? state, Brazil, presents an extraordinary scenario for improvement of the studies of helminth biodiversity. The Park has diversity mammals? species among them marsupials and armadillos are frequently seen and occasionally found dead by running over on the road. Three specimens of opossum Didelphis albiventris and two of armadillo Dasypus novemcinctus were found dead in the Park and their viscera were donated by Funda??o Museu do Homem Americano (FUMDHAM) to be studied in Instituto Oswaldo Cruz. Helminths collected in intestine were fixed in alcohol 70% or formal 4%. Parasites were clarified in glycerin for studies in microscopy of light. Some specimens were post-fixed in 1% OsO4 and potassium ferrocyanide 0.8%, dehydrated in alcoholic series, and conducted to critical point with CO2 coated with gold and visualized through scanning electron microscopy. Genomic DNA of the parasites was extracted using QIAmp DNA Mini Kit, and two set of primers were designed to polymerase chain reaction and amplicons sequenced. The species found were Aspidodera raillieti, and A. subulata from Didelphis albiventris and A. binansata, A. vazi and Hadrostrongylus speciosum from Dasypus novemcinctus from the Serra da Capivara National Park, Piau? State, Brazil were studied herein. New ultrastructural data of A. binansata and A. vazi were obtained. Sequences of cytochrome c-oxidase subunit 1 of mitochondrial DNA (mtDNA cox-1), partial mitochondrial 16S rDNA (rnnL), new sequence of partial 18S rDNA (SSU), internal transcriber spacers (ITS) 1, and 2 and 5.8S rDNA gene, and new sequence of partial 28S rDNA (LSU) gene of A. raillieti are presented. Genetic data includes the first sequence of SSU and LSU for A. raillieti and first LSU gene for Aspidoderidae. Additionally, first sequence of 16S rDNA of A. vazi was obtained. Phylogenetic analysis of maximum-likelihood using LSU gene showed Heterakoidea (represented by Aspidoderidae and Heterakidae) compose clade strongly supported (100%) and considered sister-group of Cosmocercoidea, represented by Rondonia rondonia and Orientatractis moraveci (Atractidae). Ramsonnematoidea, Rhigonematoidea and other Cosmocercoidea represented by Cosmocercoides pulcher and C. tonkinensis (Cosmocercidae) appear in a separeted clade with high statistical support. Cosmocercoidea is considered a paraphyletic group. New ultrastructural, genetic and of geographical distribution are presented and discussed. =========== CHAPTER II - The diagnosis of helminth eggs is routinely performed in the areas of human and veterinary parasitology as it provides a quick and low cost result for the treatment of parasitic diseases. In the Serra da Capivara National Park (PNSC), Piau?, Brazil, archaeological sites have revealed helminth eggs obtained in coprolites dating back thousands of years. Specific identification of eggs is difficult without the adult parasites being properly identified. The objective of this work was to study the biodiversity of helminth eggs of wild mammals from the PNSC, after identification of adult parasites. Seven species of wild mammals from a total of 16 specimens found dead were examined: deer, wild pig, agouti, ocelot, dog-eating fox, opossum and armadillo. The parasites collected from the gastrointestinal contents were identified by morphology and genetics. The eggs obtained from female adults were measured and photographed. A total of 12 species of helminth and their eggs were found, being 1 Acanthocephala and 11 Nematoda species. In the phylum Acanthocephala, Oncicola venezuelensis was found and among the Nematoda, four species of Aspidoderidae (Aspidodera raillieti, A. subulata, A. binansata and A. vazi), two Trichonstrongyloidea (Haemonchus sp. and Trichostrongylus colubriformis), two Molineidae (Molineus sp. and Hadrostrongylus speciosum), a Toxocaridae (Toxocara canis) and two Nematoda gen. sp. unidentified were reported. Our data compared with the eggs obtained from fresh faeces corroborate the presence of Aspidoderidae and Trichostrongyloidea members in wild mammals in the park area. When compared to eggs obtained in coprolites, the genera Toxocara and Oncicola appear in the ancestral and current fauna of carnivores, and is likely that species within this genus may be keeping their lifecycles for millennia in the park. In addition, an identification key to the species found in this study was designed to serve as an aid in the diagnosis of species. These data become important because they can serve as a comparative basis for the studies of current and ancestral fauna of helminths occurring in the park. |
