Abstract:
:The survival of M. leprae and M. tuberculosis in the human host is dependent upon their ability to produce gene products that counteract the bactericidal activities of macrophages. To identify such mycobacterial genes and gene products, recombinant DNA libraries of mycobacterial DNA in E. coli were passed through macrophages to enrich for clones carrying genes that endow the normally susceptible E. coli bacteria with an enhanced ability to survive within macrophages. Following three cycles of enrichment, 15 independent clones were isolated. Three recombinants were characterized in detail, and each confers significantly enhanced survival on E. coli cells carrying them. Two of the cloned genetic elements also confer enhanced survival onto M. smegmatis cells. Further characterization of these genes and gene products should provide insights into the survival of mycobacteria within macrophages and may identify new approaches of targets for combatting these important pathogens.
