A paracoccidioidomicose é a micose sistêmica mais prevalente na América Latina, principalmente no Brasil. Apesar de existirem vários estudos sobre o diagnóstico e patologia dessa micose, pouco se conhece sobre a ecologia do agente etiológico Paracoccidioides brasiliensis. Seu habitat ainda não foi determinado, mas provavelmente o fungo vive saprofiticamente no solo. Há também pouca informação quanto a participação de outras espécies de animais na eco-epidemiologia do fungo e os isolamentos obtidos de animais como morcego e pingüim não foram reprodutíveis. Até o presente, o fungo tem sido isolado com maior freqüência do tatu, Dasypus novencinctus. Estudos soroepidemiológicos demonstraram que a infecção é freqüente em cães, principalmente da área rural e recentemente foi relatado o primeiro caso de paracoccidiodomicose natural em cão. O papel de outras espécies de animais na eco-epidemiologia do fungo ainda não está esclarecido Palavras-chave: Paracoccidioides brasiliensis. Paracoccidiodomicose. Epidemiologia. Animais silvestres.

Although many studies have been done about the pathology and diagnosis of this mycosis little is known about the eco-epidemiology of the etiological agent Paracoccidioides brasiliensis. The fungus habitat also is unknown although is thought that the fungus lives as a saprobe in soil. The participation of other animal species in P. brasiliensis ecology is poorly understood and fungus isolation from animals as bat and penguin were not reproducible. The armadillos Dasypus novencinctus probably play a role in the fungus eco-epidemiology taking into account that several isolates were obtained from these animals. Seroepidemiologic studies have shown that dogs are infected by P. brasiliensis mainly in rural areas and recently was reported the first case o natural paracoccidioidomycosis in dogs. The role of other animal species in the eco-epidemiology of P. brasiliensis remains doubtful.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
