Comparison of biofilm production and virulence genes distribution among human and canine isolates of .

Background: is an important human and animal pathogen that can cause a wide range of infections due to numerous virulence factors.

Aims: The aim of this study was to compare biofilm formation ability with different virulence factors such as bacterial motility, genes encoding biofilm associated proteins, and Panton-Valentine leukocidin (PVL) among human and canine isolates of

Methods: A total of 60 human (30 methicillin sensitive (MSSA) and 30 methicillin resistant . (MRSA)) and 17 canine (all MSSA) isolates of were tested for the capability of biofilm production, motility assay, and presence of genes encoding virulence factors: (encoding intercellular adhesion), (encoding biofilm-associated protein), (encoding fibronectin-binding protein A), (encoding collagen-binding protein), and (encoding PVL).
