Currently we are utilizing biotechnologies to “Fingerprint” S. aureus, to trace the
pathogen from its reservoir to fomite to the host, the cow. We also
have projects designed to examine the role S. aureus exotoxins have
as superantigens in mastitis, and their affect on milk quality. We
are applying similar technologies in an effort to control Mycoplasma
sp. mastitis.
Specific Research Areas
Control of S. aureus mastitis in heifers.
Control of S. aureus mastitis in cows through the maintenance of
healthy teat skin condition.
Exotoxins in milk: affects on milk quality and mammary immunity.
Determination of reservoirs of Mycoplasma sp. that cause mastitis.
