title: Detection and diagnosis of mycobacterial pathogens using PCR.
abstract: In the year 2001, it is estimated that 3 million people will die from tuberculosis, caused by the infectious agent, Mycobacterium tuberculosis. After decades of decline in the disease, the resurgence of tuberculosis seen worldwide in the 1990s sparked a renewed interest and commitment of funds for research into M. tuberculosis and other pathogenic mycobacterial species. The discovery of the PCR in the 1980s has had a major influence on the progress made possible in the study of these fastidious, tough-walled and slow-growing mycobacterial species. In the last 10 years, PCR has allowed us to amplify parts of the genome, decipher the nucleotide sequence, discover new mycobacterial species, determine epidemiological relationships between strains and identify genetic changes involved in drug resistance.
