Abstract

Novel molecular tools and genetic methods were developed to isolate genomic fragments of Mycobacterium tuberculosis that may be associated with virulence. We sought to restore virulence, a characteristic of M. tuberculosis that is correlated with growth rate in mouse spleen and lung tissue, to the avirulent strain H37Ra by complementation. A representative library of the virulent M. tuberculosis strain H37Rv was constructed and transformed into H37Ra. Enrichment for individual faster-growing recombinants was achieved by passage of pools of H37Ra transformants harboring the H37Rv library through mice. A molecular strategy was devised to isolate and clone the H37Rv genomic DNA fragment ivg, which conferred a more rapid in vivo growth rate to H37Ra.
