Abstract
MRSA-ST9-t4358 from pigs and pig handlers were analysed for exoproteins profiles. Similar protein patterns with variation in protein spot intensity were observed. No significant variation among the protein profiles indicates that transmission of MRSA-ST9 from pig to human or vice versa, do not strongly alter the gene expression patterns. Indirectly, virulence factors that acquired from pig environment might have chance to be expressed in human host.
