Microarrays for Mycobacterium tuberculosis.

This special microarray issue of Tuberculosis recognises the important contributions of M. tuberculosis whole genome DNA microarrays to tuberculosis research by bringing together a range of papers that address M. tuberculosis physiology, host-pathogen interactions, mechanisms of drug action, in vitro and in vivo gene expression, host responses, comparative genomics and functional analysis of particular genes. A number of complete datasets of M. tuberculosis mRNA expression levels are provided to facilitate multiple cross-condition comparison. Microarrays represent one of the new functional genomics technologies exploiting genome sequence information that will bring us closer to realising the scientific and moral imperatives of better vaccines, diagnostics and new drugs for the control of tuberculosis throughout the world.
