Caracterização bioquímica e molecular de Cryptococcus spp. isolados de excretas ambientais de pombos (Columba livia domestica)

Abstract:  RESUMOOs pombos possuem uma rica diversidade de microrganismo, entre eles fungos sapróbios, como do gênero Cryptococcus, que podem atuar como agentes patogênicos para o homem e animais. Objetivou-se o isolamento, a caracterização bioquímica e a molecular de amostras de Cryptococcus spp. de excretas ambientas de pombos. Foram colhidas 100 amostras ambientais de pontos equidistantes e representativos da área da cidade de Araçatuba, São Paulo. As amostras foram rasteladas do solo de vias públicas, armazenadas e… Show more

“…However, each species complexes behaves differently, with the C. neoformans species complexes being more associated with the bird, bat, and soil excreta (COLOMBO et al, 2015;VIEILLE et al,2018), unlike the C. gattii species complexes that is present in dust, leaves, fruits, plants and insects (ACHESON et al, 2018), and the species C. laurentii in vegetables, milk and also in bird excreta (GUPTA et al,2018). Another important consideration is that the locations of the isolates configure a micro-niche, indicating that the positive isolates tend to appear close to each other.…”

“…In their natural habitat, species of the genus Cryptococcus can be found in various organic substrates in a saprophytic form, often being related to rich sources of nitrogen (WATKINS et al,2017). The species of the C. neoformans complexes are more associated with dry excreta of birds and soil, also being reported in guano from pigeons in urbanized regions, bats, and birds in captivity (VIEILLE et al,2018;COLOMBO et al,2015;TENCATE et al, 2012;FILIÚ et al,2002). Differently, the C. gattii complexes are associated with decaying plant materials, bark, flowers, and leaves of trees being isolated in several tree species in different countries (BENTES et al, 2019;WATKINS et al,2017;HERKERT et al,2017).…”

“…Colorações como a mucicarmim de Mayer permitem a visualização da cápsula que se cora fortemente de vermelho. Já a coloração de Fontana-Masson evidencia o depósito de melanina produzida por fungos desse gênero (Colombo, 2015).…”

“…Até a década de 80 esta doença recebeu pouca notoriedade, porém com o crescimento do número de pacientes com o vírus da imunodeficiência humana (HIV) notou-se que mais de 80% das infecções criptocócicas na época foram relatadas nesse grupo de pacientes, com uma prevalência variando de 2 a 10% nos Estados Unidos, Europa Ocidental e Austrália e 5 a 30% na África (Colombo, et al, 2015). A mortalidade geral é estimada em 10% nos países desenvolvidos e 43% nos países emergentes (Hurtado, et al, 2019).…”
