The first mycobacteriophage was isolated in 1947, and since that time over 250 of these viruses have been identified. Phages have made a significant contribution to our knowledge of mycobacteria over the past fifty years, and following the development of typing techniques in the 1960s and 1970s they were widely used in epidemiological studies of tuberculosis. Unfortunately, attempts to use lytic phages therapeutically during tuberculosis infection have so far failed to elicit cure in experimentally infected animals. During the past decade phages have become important in molecular studies of mycobacteria, both in terms of studying phage biology and as tools in recombinant DNA technology, thus facilitating the investigation of mycobacterial pathogenesis. Today their potential as diagnostics reagents is also being realised with the development of exciting new techniques for rapid bacterial detection and drug susceptibility testing. This review outlines the history of these remarkable organisms, from their discovery fifty years ago to the current developments in rapid diagnostic techniques.
