The research of my laboratory focuses on molecular aspects of the pathogenesis of Mycobacterium tuberculosis, the bacterial agent responsible for the infectious disease, tuberculosis (TB). Despite the existence of effective antibacterial drugs and a partially effective vaccine for more than half a century, TB still remains the cause of 2 million deaths worldwide each year - the most due to any single infectious agent. This situation reflects very poorly on the current level of understanding of the pathogenic processes associated with this important pathogen.
Although early studies considered TB strains to be restricted in terms of their genetic and antigenic variability, more recent evidence indicates that M. tuberculosis has evolved into several genetically diverse lineages of strains that are likely to possess unique attributes related to the transmission and development of disease. My laboratory utilizes a combination of microbial genetics, biochemistry and whole animal (mouse) in vivo infection studies to investigate the array of metabolic and virulence strategies available to this phenotypically diverse pathogen. Increasing our knowledge and understanding of this diversity will greatly enhance future efforts aimed at developing new strategies to successfully diagnose and treat TB disease.
