Antimicrobial Resistance and Lipidomics
Research DescriptionDr. Mishra's research focuses on the growing health issue of antimicrobial resistance. His lab studies adaptations associated with membrane lipids of Candida, Staphylococci, Enterococci and Streptococci that confer resistance to certain antibiotics in vitro and in vivo. He also discovered the significance of Staphylococcal carotenoid augmented membrane fluidity/rigidity and its implications in resistance to host defense peptides and in vivo virulence in an endocarditis model. Further understanding microbial adaptation to the host in the setting of anti-infective agents aims to open new doors to anti-infective strategies addressing the current challenge of conventional antibiotic resistance.
