DAIRY MANAGEMENT AND REDUCTION OF MASTITIS. Our research efforts are designed to examine new methods of control of contagious mastitis. These efforts are principally directed at control of Staphylococcus aureus and Mycoplasma sp. mastitis. Our focus is directed at the development and validation of strategies to control this disease through applied and basic research. Currently we are utilizing biotechnologies to "Fingerprint" S. aureus and Mycoplasma sp, to trace the pathogen from its reservoir to fomite to the host, the cow, for these two pathogen types. We also study the effectiveness of standard milking procedures to reduce mastitis and improve milk quality.

Specific Research Areas:

• Control of S. aureus mastitis in cows through the vaccination.
• Exotoxins in milk: affects on milk quality and mammary immunity.
• Determination of reservoirs of Mycoplasma sp. that cause mastitis.
