Fungi Isolated From the Excreta of Wild Birds in Screening Centers in Pelotas, Rs, Brazil

Abstract

The identification of the fungal species belonging to the healthy microflora in animals is a precondition for the recognition of pathological processes causing them. The aim of this study was to investigate the presence of potentially pathogenic fungi in the feces of wild birds collected in Screening Centers. Samples were collected from the feces of 50 cages with different species of birds. The samples were processed according to the modified method STAIB and the plates incubated at 32 °C for up to ten days with daily observation for detection of fungal growth. The isolation of the following species was observed: Malassezia pachydermatis, Candida albicans, C. famata, C. guilliermondii, C. sphaerica, C. globosa, C. catenulata, C. ciferri, C. intermedia, Cryptococcus laurentii, Trichosporon asahii, Geotrichum klebahnii, Aspergillus spp., A. niger and Penicillium spp. Knowing the character of some opportunistic fungi is important in identifying them, facilitating the adoption of preventive measures, such as proper cleaning of cages, since the accumulation of excreta may indicate a risk for both health professionals and centers for screening public health.

Cryptococcus albidus var. albidus Isolated from Turquoise-Fronted Parrots (Amazona aestiva: Psittacidae) Kept in Captivity: A Probable Reservoir Ecological of Fungal Specimen

“…This fact occurs because dried bird droppings have fertility characteristics for fungal species growth due to high concentrations of nitrogenous bases and, as they become old, they contain higher concentrations of fungi than when they have recently been eliminated [14,15,30].…”

“…It is possible to verify that several studies evidencing the importance of bird dropping as a suitable substrate for the growth of yeasts and filamentous fungi [8][9][10][11][12][13][14][15]. Birds easily conduct the agent in the environment through its feces and become a zoonotic problem due to its proximity with the humans, explained by the fact that it is a peridomestic animal.…”

Diversity and abundance of human‐pathogenic fungi associated with pigeon faeces in urban environments

“…Although culture-independent, high-throughput sequencing approaches are extremely sensitive for detection of rare or uncultur- Guz, 2011;Lo Cascio et al, 2007;Mancianti, Nardoni, & Ceccherelli, 2002;Mendes et al, 2014;Wojcik, Kurnatowski, & Blaszkowska, 2013), have been isolated from pigeon faeces in only two studies, both conducted in Seoul (Chae et al, 2012;Jang et al, 2011). Whether this represents simple sampling bias or specialization of these species in Seoul requires further investigation.…”

Frequência de Cryptococcus spp. e outras leveduras com potencial patogênico em excretas de aves silvestres em três munícipios do estado de São Paulo

“…Diversas espécies de Candida, incluindo as de grande interesse médico, C. albicans, C. tropicalis, C. glabrata, C. krusei, Meyerozima guilliermondii (C. guilliermondii), Pichia anomala (C. pelliculosa) e outras menos frequentes em infecções humanas, como C. famata já foram observadas em excretas de aves silvestres, em cativeiro ou ambiente natural, em distintos continentes (MANCIANTI et al, 2001;RASO et al, 2004;ABEGG et al, 2006;FILION et al, 2006;LUGARINI et al, 2008;SANTOS et al, 2009;BRILHANTE et al, 2010;MARINHO et al, 2010;VLAHOVIC et al, 2010;MENDES et al, 2014;DYNOWSKA et al, 2015).…”
