No. of bitstreams: 1 dissertacao_ana_albano.pdf: 675901 bytes, checksum: 731cd5d7d9c76798f77ba8cd9a5b2e7a (MD5) Previous issue date: 2009-07-23 / The study of the infectious diseases in wild animals, in special the illnesses caused by fungi, have a few stories related with the incidence and distribution of the diverse ethiologic agents in captive populations and especially in the free ranging animals. The identification of the fungical species that are part of microbiota in healthful animals is primordial condition for the recognition of causers of pathological processes. The objective of this work was the isolation and the identification of fungi that is present in healthy wild animals or not, received in Screening Centers, and the respective study of mycosis caused by the fungi in wild animals in the states of the Rio Grande do Sul and Mato Grosso do Sul. The material collections had been carried through sterilized swabs for the external acoustic meatus and of the technique of "square of the carpet for the tegument of the wild animals in evaluation. The samples had been collected from 83 animals and the sorts of isolated fungi in this study had been Aspergillus sp., Candida spp., Penicillium sp., Geotrichum sp., Malassezia sp., Trichophyton sp., Trichophyton mentagrophytes, Fusarium sp. e Scopulariopsis sp. In 33 animals that had presented injuries it had fungical isolation in 97%. Amongst the birds, 100% of the collected animals had presented clinical signals, with isolation of the Candida sp. e Aspergillus sp. in 81% (n=13) and 19% (n=3) of the animals, respectively. In the group of the mammals, the total of animals that had presented clinical signals was of 23,07% (n=15), and all the genus of isolated fungi in this study were present, the exception of Fusarium sp. In the group of the reptiles, represented for two units of the specie Chelonia mydas, it had growth of Candida lipolytica in an individual and Fusarium sp. in another one, and they both presented clinical signals. The results obtained in the samplings had allowed to conclude that fungi are present in wild animals, therefore, it s necessary the continuity of the studies on microbiota and fungical illnesses in wild animals in rehabilitation: and its respective ethyological agents, in way that new findings can make possible the prevention and the treatment of mycoses, improving the carried attendance through of more directed and specify form in the services of primary attention to wild animals in Brazil. / O estudo das doenças infecciosas em animais silvestres, em especial as causadas por fungos, são pouco relatadas relacionando sua incidência e a distribuição dos diversos agentes etiológicos nas populações cativas e, em especial nas de vida livre. A identificação das espécies fúngicas que fazem parte da microbiota em animais saudáveis é condição primordial para o reconhecimento daquelas causadoras de processos patológicos. O objetivo deste trabalho foi isolar e identificar fungos presentes em animais silvestres sadios ou não, recebidos em Centros de Triagem, e o respectivo estudo das micoses causadas pelos mesmos em animais silvestres nos estados do Rio Grande do Sul e Mato Grosso do Sul. As coletas de material foram realizadas através de swabs estéreis para o meato acústico externo e da técnica do "quadrado do carpete para o tegumento dos animais silvestres em avaliação. As amostras foram coletadas de 83 animais silvestres e os gêneros de fungos isolados neste estudo foram: Aspergillus sp., Candida spp., Penicillium sp., Geotrichum sp., Malassezia sp., Trichophyton sp., Trichophyton mentagrophytes, Fusarium sp. e Scopulariopsis sp. Nos 33 animais que apresentaram lesões houve isolamento fúngico em 97%. Dentre as aves, 100% dos animais coletados apresentaram sinais clínicos, com isolamento dos gêneros Candida sp. e Aspergillus sp. em 81% (n=13) e 19% (n=3) dos animais, respectivamente. Já no grupo dos mamíferos o total de animais que apresentaram sinais clínicos foi de 23,07% (n=15), sendo que todos os gêneros de fungos isolados neste estudo estavam presentes, a exceção de Fusarium sp. No grupo dos répteis, representado por dois exemplares da espécie Chelonia mydas (tartaruga-verde), houve crescimento de Candida lipolytica em um indivíduo e Fusarium sp. em outro, sendo que ambos apresentavam sinais clínicos. Os resultados obtidos evidenciaram a presença de fungos em animais silvestres, sendo, portanto, necessária a continuidade dos estudos sobre a microbiota e as doenças fúngicas em animais silvestres em reabilitação e seus respectivos agentes etiológicos, de modo que novos achados possam possibilitar a prevenção e o tratamento das micoses, qualificando o atendimento realizado de forma mais direcionada e específica nos serviços de atenção primária a animais silvestres no Brasil.
