Pathogens of public health concern shared by domestic and wild animals in a pluriactive farm / Patógenos importantes em saúde pública compartilhados por animais domésticos e silvestres em propriedade pluriativa pluriactive farm

Abstract

The objectives of this study were to identify the occurrence of pathogens of public health concern in wild and domestic animals within a pluriactive farm, to detect the presence of genes coding enterotoxins in Staphylococcus aureus isolates and to identify the occurrence of the same strain in different animals. Fecal samples of up to five specimens of each domestic and wild species were collected. Isolates were obtained, were realized the species identification/confirmation, detection of enterotoxigenic genes, the comparison of molecular profiles and were identified the Methicillin-resistant S. aureus (MRSA). Total percentage of samples from which some isolate was obtained was 7.9% (19/241). S aureus was present in 7.5% (12/160) of domestic animals and in 6.2% (5/81) of wild animals. MRSA was isolated from 3.7% (6/160) of domestic and from 4.9% (4/81) of wild animals. Yesrinia enterocolitica was isolated from 1.2% (1/81) of wild animals and Samonella from 0.6% (1/160) of domestic animals. 35.3% (6/17) of S. aureus isolates had one of the enterotoxigenic genes. Indistinguishable and closely related isolates were found in domestic and wild animals, which confirms that there is a circulation of strains between animals or at least indicates the presence a common source of infection between them.
