Typing of<i>Staphylococcus aureus</i>isolated from bovine mastitis cases in Australia and India

Abstract

Both PCR and the serological method demonstrated that CP5 and CP8 are the predominant capsular types in Australia, whereas CP5 is the predominant capsular type in India. The study also demonstrated a strong correlation between both methods of typing for CP1, CP5, CP8 and non-typeable S. aureus strains. High-percentage prevalence of non-typeable isolates in both the countries highlights the importance of continued investigations of the identification of unique surface-associated polysaccharide antigens prevalent among S. aureus isolates for the formulation of CP- and SP-based vaccines for bovine mastitis.
