Resumo: | The Centro de Recuperação de Animais Marinhos (CRAM-FURG) is a rehabilitation center that works essentially with debilitated Magellanic penguins (Spheniscus magellanicus), aiming to rehabilitate and release them to their natural habitat. However, several of the received penguins develop aspergillosis, an opportunistic fungal disease frequently responsible for the death of captive birds, often in association with the stress experienced by these animals in captivity. This study aimed to examine a six-year period for cases of aspergillosis in Magellanic penguins undergoing rehabilitation at CRAMFURG. For that purpose, a retrospective cohort study was conducted using the institution s records of Magellanic penguins received from January 2004 to December 2009. Animals were classified in two groups: the case group included animals that died from aspergillosis, the control group included animals that survived and were released or those that died from conditions unassociated with aspergillosis. Variables examined as potential risk factors were age group, gender, oil fouling, precedence, prophylactic administration of itraconazole, time in captivity until death or release, body mass, and hematological parameters such as hematocrit and total plasmatic proteins. During this period, the institution received 366 Magellanic penguins, of which 39 were excluded from the analyses due to the insufficiency of data on their cause of death, thus 327 animals were studied. During the studied period, 66 penguins died of aspergillosis. Aspergillus fumigatus was the most frequent etiological agent (98.5%). Relative mortality by aspergillosis was 48.5% during the examined period, and the density of incidence was 7.3 lethal aspergillosis cases per 100 penguins-month. Approximately 75% of the aspergillosis cases occurred in animals received through transfers from other rehabilitation centers, and this was considered a significant risk factor for the disease, with a relative risk of greater than 3.0. Significant differences were also observed between the case and control groups in regards to their time in captivity until death, their hematocrit and total plasmatic proteins upon admission to the center, and their body mass change during the period in captivity. The findings demonstrate the negative impacts of aspergillosis on the rehabilitation of Magellanic penguins, with a high density of incidence and important mortality of these animals. |

No entanto, muitos exemplares recebidos acabam desenvolvendo aspergilose, uma doença fúngica oportunista frequentemente responsável pela morte de aves em cativeiro, associada ao estresse sofrido por estes animais. Neste sentido, este trabalho objetivou realizar um levantamento epidemiológico de seis anos da aspergilose em pinguins-de-Magalhães em reabilitação no CRAM-FURG. Para isso, foi realizado um estudo de coorte retrospectivo a partir de informações coletadas do banco de dados do CRAM-FURG referentes aos pinguins recebidos no período de janeiro de 2004 a dezembro de 2009. Os animais foram classificados em dois grupos, sendo o grupo caso referente a pinguins que morreram por aspergilose, e o grupo controle aquele composto por animais que foram liberados ou morreram por outras causas. As variáveis analisadas quanto a fator de risco foram idade, sexo, petrolização, procedência, uso de itraconazol profilático, tempo de cativeiro, peso corpóreo e parâmetros sanguíneos como hematócrito e proteínas plasmáticas totais. Durante esse período o Centro recebeu 366 pinguins de Magalhães, dos quais 39 foram excluídos do estudo por não apresentarem dados disponíveis no banco de dados sobre sua causa mortis, resultando num total de 327 animais. Durante o período estudado, 66 pinguins morreram por aspergilose, sendo Aspergillus fumigatus o principal agente etiológico encontrado, com 98,5% dos casos. A mortalidade proporcional por aspergilose foi de 48,5% no período de seis anos de estudo, e a densidade de incidência encontrada foi de 7,3 casos de aspergilose/100 pinguinsmês. Aproximadamente 75% dos casos de aspergilose ocorreram em animais procedentes de outros Centros de reabilitação, sendo este considerado um fator de risco para a doença, com risco relativo maior que 3,0. Também foram encontradas diferenças significativas entre os grupos caso e controle em relação ao tempo de cativeiro, valores de hematócrito e proteínas plasmáticas totais na chegada ao Centro, e ganho de peso durante o período de cativeiro. Os achados deste estudo demonstram a interferência negativa da aspergilose na reabilitação de pinguins-de-Magalhães, com alta densidade de incidência, e responsável por importante mortalidade destes animais.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em VeterináriaUFPelBRVeterináriaVeterináriaAspergillusFatores de riscoSphenisciformesMortalidadeAspergillusRisk factorsSphenisciformesMortalityCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIA::MEDICINA VETERINARIA PREVENTIVA::EPIDEMIOLOGIA ANIMALAvaliação epidemiológica da aspergilose em pinguins-de-Magalhães no Centro de Recuperação de Animais Marinhos FURGEpidemiological survey of aspergillosis in Magellanic penguins at the Centro de Recuperação de Animais Marinhos FURGinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/7673292751143993http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4799478H9Xavier, Melissa Orzechowskihttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4776164Z7Vargas, Gilberto D'Ávilahttp://lattes.cnpq.br/2905761117990157Meireles, Mario Carlos AraújoSilva Filho, Rodolfo Pinho dainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_rodolfo_silva.pdfapplication/pdf3168091http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2474/1/dissertacao_rodolfo_silva.pdfce68f91004a1b87e7c1c6a31886c8d10MD51open accessTEXTdissertacao_rodolfo_silva.pdf.txtdissertacao_rodolfo_silva.pdf.txtExtracted Texttext/plain108227http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2474/2/dissertacao_rodolfo_silva.pdf.txt7ec47490552faef78e2335e076f660d6MD52open accessTHUMBNAILdissertacao_rodolfo_silva.pdf.jpgdissertacao_rodolfo_silva.pdf.jpgGenerated Thumbnailimage/jpeg1363http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2474/3/dissertacao_rodolfo_silva.pdf.jpgc4e0ba0bd5ef5ab144531b425b959ac7MD53open access123456789/24742019-09-17 17:41:35.934open accessoai:guaiaca.ufpel.edu.br:123456789/2474Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2019-09-17T20:41:35Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
