Abstract
tuberculosis remains amajor health problem world wide. an estimated 1.700 million people, one third of the worlds population, are infected or have been infected with m. tuberculosis, with 2.9 million deaths due to the disease problem, and there is an urgent need for arapid and areliable diagnostic test. culturing of organisms has aspecificity that approaches 100% but it takes 3-6 weeks resulting in delay in diagnosis. when few mycobacteria are present at the site of infection, multiple cultures may also be necessary to insure apositive result. other methods used for diagnosis of tuberculosis lacks sensitivity.
