Microbiota de psitaciformes silvestres e exóticos mantidos em centros de reabilitação e triagem

Abstract

It is estimated that Brazil holds 1.832 species of wild birds that belong to the national fauna. The psitacides belong to the Psittacidae Family and they comprehend the largest group of threatened bird species. The aim of this study was to isolate and identify pathogenic fungi and bacteria, either opportunistic or for excellence, present in anatomical sites of wild and exotic birds. Therefore, study the potential of these animals as carriers of pathogens responsible for infectious diseases in other animals and humans. The project was supported by NURFS/CETAS/UFPel, PRESERVAS/UFRGS and CETAS/IBAMA. There were collected two samples from each anatomical site (cloaca, oral cavity and axilla). Half of the samples were sent to the micology laboratory and the other half was sent to the bacteriology. From the 59 animals used in this study, 49.15% (n=29) of the isolates were Aspergillus spp., 62.71% (n=37) was Penicillium spp., 59.32% (n=35) was Candida spp. (Figure 1), 37.28% (n=22) was Rhodotorula spp., 11.86% (n=7) was Malassezia spp., 6.77% (n=4) was Candida albicans, 3.38% (n=4) was Trichosporon spp. and 1,69% (n=1) was Geotrichum spp. Regarding to the bacteria found on this study, 69.49% (n=41) of the isolates were Staphylococcus spp., 22.03% (n = 13) was Streptococcus spp., 8.47% (n = 5) was Corynebacterium spp. and 6.77% (n = 4) was Bacillus spp. We concluded that fungi as Candida spp., Candida albicans, Malassezia spp., Rhodotorula spp., Trichosporon spp. and Geotrichum spp., as well as bacteria of the genus Corynebacterium, Staphylococcus and Streptococcus are part of the microbiota of several anatomical sites of psittacines from the Rehabilitation and Screening Center of IBAMA, UFPEL and UFRGS. In addition, we conclude that wild birds are potential carriers of fungi and bacteria that are pathogenic to other wild and domestic animals, as well as to humans.
