Dr. Sanjay Shukla, research scientist at the Center for Human Genetics Marshfield Clinic Research Foundation, will present “Understanding Staphylococcus aureus virulence and host susceptibility to S. aureus caused diseases” at 3 p.m. Wednesday, April 13, in Room 139 Schrenk Hall. The talk will include an investigation of an outbreak of community-associated methicillin-resistant Staphylococcus aureus in Wisconsin in the 1990s, why CA-MRSA are more virulent than methicillin-sensitive S. aureus, and host genetic susceptibility to S. aureus diseases.
