Abstract
The aim of the study was to determine the occurrence and characteristics of coagulase-positive Staphylococcus strains in the carcasses of wild birds and aviary capercaillies in south-eastern Poland. Samples from capercaillies and wild birds belonging to 12 orders and 26 species were tested. The resistance of the strains and the presence of selected virulence genes were examined. Similarity analysis of the isolates was performed using pulsed-field gel electrophoresis (PFGE). Coagulase-positive Staphylococcus strains accounted for 5.7% and belonged to the species: Staphylococcus aureus, Staphylococcus pseudintermedius and Staphylococcus delphini. Among isolated strains, 15.8% were multidrug resistant. The most frequently detected virulence genes were hla in 58% of isolates and hlb and hld in 47.4% of isolates., The results of multiplex PCR showed the presence of genes responsible for the production of enterotoxins C, B, E, and J, in single isolates. It can be concluded that coagulase-positive Staphylococcus strains accounted for a small percentage of staphylococci isolated from free-living birds in the study area. The occurrence of multidrug-resistant coagulase-positive Staphylococcus strains in aviary capercaillies suggests that they play a role in the transmission and spread of resistant strains into the environment. Free-living birds may be also a significant reservoir of enterotoxigenic Staphylococcus strains.
