Abstract
A exposição humana a fezes de animais contaminados com microrganismos patogênicos representa um risco para a saúde. A presença de fungos e leveduras em ambientes está relacionada a efeitos adversos na saúde respiratória. A abordagem objetiva para a mitigação de possíveis efeitos à saúde devido à exposição a fungos e leveduras em ambientes fechados é difícil devido à falta de diretrizes. O objetivo deste trabalho foi conhecer as condições higiênico-sanitárias, identificar e caracterizar organismos de importância médica isolados de fezes de pombos coletadas na laje de um telhado de um prédio público. Para tais pontos, a coleta de excrementos foi estabelecida e os microrganismos foram identificados por métodos bioquímicos e microbiológicos padronizados, seguidos da abordagem proteômica de MALDI-TOF para a identificação do nível de espécie. Os resultados da identificação microbiana revelaram a presença de microrganismos de importância médica nas amostras analisadas, a saber: Candida krusei, Candida rugosa, Aspergillus spp., Cryptococcus neoformans, Klebsiella pneumoniae e Trichosporon asahii. Os resultados encontrados revelam a necessidade do desenvolvimento de metodologias que permitam mitigar os riscos à saúde humana devido à exposição a agentes patogênicos no ambiente examinado.
Highlights
Exposure to bacteria, fungi and yeasts in closed environments is an important public health problem
A few specialists have the necessary knowledge about possible risks to human health from exposure to fungi and yeasts in closed environments, and the diagnosis and treatment of diseases caused by exposure to these microorganisms (CRAWFORD et al, 2015; HURRAβet al., 2017)
The conditions proved to be inappropriate, since carcasses of dead animals, feathers, bones, live pigeons, eggs of pigeons, and a thick layer of excreta were found as a potential source of environmental contamination
Summary
Fungi and yeasts in closed environments is an important public health problem. A few specialists have the necessary knowledge about possible risks to human health from exposure to fungi and yeasts in closed environments, and the diagnosis and treatment of diseases caused by exposure to these microorganisms (CRAWFORD et al, 2015; HURRAβet al., 2017). The objective approach to mitigate possible health effects due to exposure to fungi and yeasts in closed environments is difficult due to the lack of guidelines (CRAWFORD et al, 2015; HURRAβ et al, 2017). This document provides important information that can be used to mitigate risks from exposure to fungi and yeasts in closed environment, and an introductory course as well for patients subjected to this exposure (HURRAβ et al, 2017) In April 2016, the German Society of Hygiene, Environmental Medicine and Preventive Medicine, along with other medical societies from Germany and Austria, doctors and specialists from the AWMF (Association of the Scientific Medical Societies in Germany) developed a guide entitled “Medical diagnosis for indoor mold exposure.” This document provides important information that can be used to mitigate risks from exposure to fungi and yeasts in closed environment, and an introductory course as well for patients subjected to this exposure (HURRAβ et al, 2017)
