Abstract

Brazil has one of the richest and most complex biomes around the world. It is estimated that the country has approximately 1800 species of birds in national fauna. The micro-organisms from enteric microflora represents one of the major classes of pathogens for humans and animals. This particular group of organisms is characterized by ability to remain viable and infective in hostile conditions of environment. The great majority, establish infection in susceptible through the contamination of foods of animal origin, water, vegetables and fruits. Furthermore, the close contact with animals or the environment of animals are important in the transmission of pathogens from animals to humans. In addition, access of wild birds to the environment next to homes, favors peridomestic contamination of environment by feces of Psittaciformes and Passeriformes. Moreover, poor hygiene of squares and parks and lack of knowledge of the general population about the risks posed by enteric microorganisms, makes these high-risk environments to the placement of enteric pathogens to humans.Among the fecal transmission pathogens, with recognized environmental resistance and zoonotic potential and related to severe diseases in humans, it is important to note: Escherichia coli, Salmonella spp., Rhodococcus equi, coronavirus sp. Rotavirus and sp.Due to the zoonotic potential of enteric pathogens, the great diversity of birds of the Brazilian fauna, and the small number of studies in this country involving the investigation of these enteric pathogens, as well as investigation of the virulence of E. coli and R.equi isolates from Passeriformes and Psittaciformes, the purpose of present study was to evaluate the occurrence of enteric pathogens from bacterial origin, and virulence markers of E. coli and R. equi in fecal samples of wild or synanthropic birds from Brazilian fauna.
