Investigations of Microbial Fitness, Virulence, and Drug Resistance

Infectious and opportunistic pathogens are a major cause of host morbidity and mortality. In this session we explore host immunity and the mechanisms by which microbes adapt to the host environment or exposure to antimicrobial agents. Better understanding host-microbe interactions and how microbes effectively respond to stress will be key to developing more effective treatments as we continue to fight pathogens both old (Mycobacterium tuberculosis) and new (SARS-CoV-2).
