Molecular characterisation of virulence genes in Staphylococcus aureus associated with clinical bovine mastitis

Staphylococcus aureus is the most frequently isolated pathogen from bovine mastitis including subclinical, clinical, and chronic infections. Virulence factors possessed by S. aid in causing infection inflammation producing toxins proteins, which are responsible for pathogenesis of disease. In current study out 51 animals presented with clinical mastitis, was milk 18 animals. confirmed genus species level identification using polymerase chain reaction. Molecular characterization selected virulence genes thermonuclease (nuc) Panton Valentine Leucocidin (PVL) performed all isolates. Presence nuc gene observed isolates (100 %) aureus. No were found to be positive presence PVL gene. Profiling an important tool epidemiological studies can employed prevention control
