-Evolution of Bacterial Genomes
The research in my laboratory involves the use of innovative approaches to understand the basics of mycobacterial pathogenesis and evolution of bacterial genomes. Currently, we are exploiting the transcriptome of Mycobacterium tuberculosis and M. bovis, the causative agent of human and animal tuberculosis, to better understand the critical stages of persistent infection. In particular, we use gene-targeted mutational analysis alongside cellular, biochemical and molecular techniques to determine the role of a novel genomic island expressed only during infection (iVEGI) in mycobacterial survival. Some of these mutants are currently developed into effective vaccines against human and animal tuberculosis.
Other members of the laboratory investigate the pathogenesis and evolution of M. avium ss. paratuberculosis (M. ap), the causative agent of Johne’s disease in cattle. In particular, we address questions related to the very early stages (few hours) of intestinal invasion by M. ap bacilli as well as virulence factors associated with chronic infection. With the availability of the genome sequences of members of M. avium complex, we are currently reconstructing the evolutionary history of M. avium complex. We are determined to develop a better vaccine than the current inactivated vaccine to control Johne’s disease in sheep, goat flocks and cattle dairy herds.
