Surtos interespecíficos de dermatomicoses por Microsporum canis e Microsporum gypseum

Abstract

. et al. Surtos interespecíficos de dermatomicoses por Microsporum canis e Microsporum gypseum. Rev. Saúde Pública, 28: 337-40,1994. As dermatomicoses dos animais domésticos constituem zoonoses importantes, urna vez que estes mantêm estreito contato com a espécie humana, dada a alta infectividade observada nesses processos. Relata-se a ocorrência de sete surtos de dermatomicoses, um por M. gypseum envolvendo um gato e um indivíduo do sexo feminino e os outros por M. canis envolvendo 20 indivíduos da espécie humana (adultos, jovens e crianças de ambos os sexos), 5 cães, 16 gatos e um macaco gibão (Hylobates lar).Descritores: Dermatomicose, epidemiologia. Microsporum, isolamento. Zoonose, transmissão. IntroduçãoAs dermatomicoses dos cães e gatos constituem zoonoses de importância, uma vez que estes são, dentre os animais domésticos, os que mantêm mais estreito contato com a espécie humana, particularmente com as crianças, altamente susceptíveis a esses processos 21,29,30 . Por representarem alta percentagem das dermatopatias, os animais assumem papel relevante na clínica veterinária. As lesões clinicamente evidentes preocupam o proprietário, levando-o a procurar ajuda do profissional para diagnóstico, tratamento e orientação 6,7,10,13 . Numerosos surtos por espécies do gênero Microsporum são referidos na literatura internacional. Assim, verificam-se relatos de M. canis determinando dermatomicose no homem e, concomitantemente, nos animais em diferentes continentes como,

Filamentous Fungi Isolated From the Fur Microbiota of Callitrichids Kept in Captivity in Brazil

“…and a whitehanded gibbon (Hylobates lar) was previously reported in Brazil. 6 However, nondermatophyte fungi were isolated from the species investigated in our study, and no cutaneous abnormality was observed in the animals. Kawai et al 13 previously reported similar findings in their investigation about the fungal microbiota of the skin surface of 74 cynomolgus monkeys (M. fascicularis) studied in Japan.…”

“…Furthermore, urban expansion has limited the territory available to animals and has provided greater contact between humans and nonhuman primates, increasing the risk of zoonotic infections for both groups, as observed in cases of dermatophytosis. 6,18 Opportunistic fungal infections have been reported in humans under immunosuppressive conditions, but there are few studies in that regard in the veterinary literature. 12 Environmental degradation and captivity constitute stress factors that negatively influence the immune system, especially for animals caught in the wild.…”

“…The memorable researches of Robert Remak and David Gruby in the mid-19th Century, as well as by Raymond Sabouraud in the early 20th Century, marked the beginning of a new era in which the clinical role of keratinolytic fungi as agents of infection was established. 4,6,14 The relationship between external microbiota and factors that predispose an animal to opportunistic infections is poorly understood for most exotic species. The captive environment is artificially designed and imposes some restrictions on wildlife.…”

Isolation of Microsporum gypseum from the haircoat of health wild felids kept in captivity in Brazil

“…canis can be isolated in up to 88% of apparently healthy cats (38); this asymptomatic carrier state of the domestic cat is of utmost importance because animal host reservoirs represent an infection risk for the human population and a public health concern (5,38). Cats which live in groups, which have contact with non-domesticated cats or that are carries of viral immunosuppressor infections represent risks for dermatophytosis dissemination (27,35,38).…”

Isolation of dermatophytes in wild felids from screening centers

“…Among these, M. canis assumes a notable relevance as the most isolated dermatophyte in cats (Gambale et al , 1993, Pier and Moriello, 1998, Zaror et al , 1986). M. canis can be isolated in up to 88% of apparently healthy cats (Zaror et al , 1986); this asymptomatic carrier state of the domestic cat is of utmost importance because animal host reservoirs represent an infection risk for the human population and a public health concern (Costa et al , 1994a, Zaror et al , 1986). …”
