Resumo: | This study aims to get to know potential risk factors for dogs and cats presenting positive pathogenic fungus culture diagnosis. A retrospective observational study on fungus infections diagnosed in dogs and cats in southern Brazil between 1980 and 2011 was performed. One thousand seven hundred and thirty-nine clinical sample records of dogs and cats a with suspicion of fungal infections from the Diagnostic and Research Center in Veterinary Mycology (MICVET) and the Regional Diagnosis Laboratory (RDL), both belonging to the Veterinary School of the Pelotas Federal University (FAVET UFPel) were analyzed. Fungal growth was detected in 52,85 % of the samples, of which 37,49 % were pathogenic-related. The winter season presented a 29,49 % pathogenic fungus diagnosis positivity; of these, 48,76 % of the samples were from female animals and 44,11 % of male, whereas 7,13 % were unidentified; also, 79,30 % of the positive samples were of dogs and 20,70 % of cats; the highest positivity rate (26,80 %) occurred in young animals up to two years old. The three most common fungus infections were malasseziosis at a 59,98 % incidence rate, dermatophytosis 18,56 % and sporotrichosis 14,26 %. The species Malassezia Pachydermatis was isolated from 100 % of malasseziosis cases, and 78,98 % malasseziosis cases were otitis-related, most of which in dogs (94,88 %). 24,49 % of dogs were up to two years old, and 54,7 % of canine cases occurred in females. Cocker Spaniel (10,24 %) and Poodle (8,89 %) were the most affected breeds. Dermatophytes were isolated in 18,56 % fungal infections, and Microsporum canis was the most commonly isolated species (57,78 % of dogs and 77,42 % of cats). Dogs presented a 74,38 % rate of cases and the one 24 month age group encompassed 56,67 % of records in dogs and 64,52 % in cats. The most affected breeds were Yorkshire Terrier (10%) and Persian (29,03 %). Sporothrix schenckii infection showed a 13,98 % rate in dogs and an 80,02 % rate in cats. Isolation occurred in 71,25 % cases in male cats; as to dogs, a significant gender-related difference was not found. The two to four year age group showed a 23,75 % occurrence rate. Crossbred animals corresponded to 82,50 % of the cases in cats and 53,85 % in dogs. These data demonstrated that most cats and dogs with fungal infections are young animals, with females showing a greater predisposition; however, no significant differences as to breed, animal fur or seasonality were found. The three most frequently isolated fungi in dogs and cats in southern Brazil were Malassezia pachydermatis, dermatophytes and Sporothrix schenckii. |

Foi realizado um estudo observacional de caráter retrospectivo das infecções causadas por fungos, diagnosticadas em cães e gatos na região Sul do Brasil, no período de 1980 a 2011. Foram analisados 1.739 registros de amostras clínicas de caninos e felinos com suspeitas fúngicas, provenientes dos bancos de dados do Centro de Diagnóstico e Pesquisa em Micologia Veterinária (MICVET) e do Laboratório Regional de Diagnóstico (LRD), ambos da Faculdade de Veterinária da Universidade Federal de Pelotas (FAVET- UFPel). Houve crescimento fúngico em 52,85% das amostras, das quais 37,49% corresponderam ao crescimento de fungos patogênicos. O inverno 29,75% de frequência nos diagnósticos positivos para fungos patogênicos, 48,76% das amostras positivas eram de fêmeas, 44,11% machos e 7,13% não identificados, das amostras positivas 79,30 pertenciam a caninos 20,70% a felinos. A maior frequência, 26,80%, de casos positivos ocorreu em animais jovens, com até dois anos de idade. As três infecções fúngicas de maior ocorrência foram a malasseziose 59,98%, dermatofitose 18,56% e esporotricose 14,26%. Em 100% dos casos de malasseziose foi isolada a espécie Malassezia pachydermatis, em 78,98% dos casos a malasseziose era relacionada à otite, a maioria de 94,88% ocorreram em caninos. Nos caninos 20,49% tinham até dois anos de idade e 54,72% dos casos eram de fêmeas. As raças definidas Cocker Spaniel (10,24%) e Poodle (8,89%) foram as mais afetadas. O isolamento de dermatófitos ocorreu em 18,56% das infecções fúngicas, Microsporum canis foi a espécie mais isolada em caninos 57,78% e felinos 77,42%. Os caninos tiveram frequência de 74,38% dos casos e a faixa etária entre um e 24 meses teve 56,67% dos registros em caninos e 64,52% nos felinos, as raças Yorkshire Terrier 10%, e Persa 29,03% foram as mais afetadas. A infecção por Sporothrix schenckii teve frequência de 14,26%, sendo 13,98% em caninos e 86,02% em felinos. Em 71,25% o isolamento se deu em machos felinos, em caninos não houve diferença significativa relacionada ao sexo. A idade entre dois e quatro anos teve ocorrência de 23,75%. Os animais SRD corresponderam a 82,50% dos casos em felinos e 53,85% em caninos. Conclui-se que os dados gerais demonstram que a maioria de caninos e felinos com infecções fúngicas são animais jovens, com maior predisposição de fêmeas, não havendo diferença significativa para raça, comprimento do pelo e sazonalidade. Os três fungos com maior frequência de isolamentos em caninos e felinos na região sul do Rio Grande do Sul foram Malassezia pachydermatis, dermatófitos e Sporothrix schenckii.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em VeterináriaUFPelBRVeterináriaFungosMalassezia pachydermatisDermatófitosSporothrix schenckiiCaninosFelinosEpidemiologiaFungiMalassezia pachydematisDermatophytesSporothrix schenckiiDogsCatsEpidemiologyCNPQ::CIENCIAS AGRARIAS::MEDICINA VETERINARIAEstudo retrospectivo das micoses e micotoxicoses animais na região sul do BrasilA retrospective study of animal mycoses and mycotoxicoses in southern Brazilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://lattes.cnpq.br/0250285937836509http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4799478H9Meireles, Mario Carlos AraújoGomes, Angelita dos Reisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALdissertacao_angelita_reis_gomes.pdfapplication/pdf850060http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2484/1/dissertacao_angelita_reis_gomes.pdf1f4da5ff7cd0955fa9cc9d07431a3c49MD51open accessTEXTdissertacao_angelita_reis_gomes.pdf.txtdissertacao_angelita_reis_gomes.pdf.txtExtracted Texttext/plain158498http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2484/2/dissertacao_angelita_reis_gomes.pdf.txt73bf767b40613a6ea91e1fe809fd4991MD52open accessTHUMBNAILdissertacao_angelita_reis_gomes.pdf.jpgdissertacao_angelita_reis_gomes.pdf.jpgGenerated Thumbnailimage/jpeg1369http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/2484/3/dissertacao_angelita_reis_gomes.pdf.jpg6c493ec1b9f9d2b8a3262ff16f9fe5c1MD53open access123456789/24842019-09-18 20:57:25.754open accessoai:guaiaca.ufpel.edu.br:123456789/2484Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2019-09-18T23:57:25Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
