By 2035, more than 500 million people worldwide will be diagnosed with diabetes. Individuals with diabetes are prone to frequent and invasive infections that commonly manifest as skin and soft tissue infections (SSTIs). Staphylococcus aureus is the most commonly isolated pathogen from diabetic SSTI. S. aureus is a problematic pathogen that is responsible for tens of thousands of invasive infections and deaths annually in the US. Most S. aureus infections manifest as skin and soft tissue infections (SSTIs) that are usually self-resolving. However, in patients with comorbidities, particularly diabetes, S. aureus SSTIs can disseminate resulting in systemic disease including osteomyelitis, endocarditis and sepsis. The goal of my research is to understand the complex interactions between bacterial pathogens and the host innate immune response with focus on S. aureus and invasive infections associated with diabetes. My research is roughly divided into two project areas in order to understand the contributions of the pathogen and the host response to invasive infections associated with diabetes. Project 1: Defining mechanisms of immune suppression in diabetic infections. Project 2: Determine the role of bacterial metabolism in virulence potential and pathogenesis.
