Staphylococcus Aureus Biofilms Interfere With Macrophage Antimicrobial Responses Through Differential Gene Regulation, Toxin Production, And Purine Metabolism, Tyler D. Scherr

Theses & Dissertations

Staphylococcus aureus (S. aureus) is an opportunistic pathogen that is a leading cause of both nosocomial and community-associated infections. Armed with a myriad of virulence factors and the propensity to form a biofilm on native tissues and implanted medical devices alike, S. aureus infections represent a very real public health threat, the treatment of which results in an excessive economic burden. S. aureus biofilm infections are notoriously recalcitrant to antibiotic therapy and adept at evading and neutralizing the host immune antimicrobial response. Previous studies from our laboratory have shown that S. aureus biofilms are able to cause persistent …
