Abstract
Tuberculosis (TB) is a common and deadly infectious disease caused byMycobacterium tuberculosis and rarely by other subspecies of the M. tuberculosiscomplex, such as Mycobacterium bovis. Enzyme-linked immunosorbent assay (ELISA) for diagnosis of tuberculosis has been widely explored over the years. The purpose of this study was to reduce the time duration required for the diagnosis of tuberculosis. We have extracted antigens from the M. tuberculosis strain H37Ra. Antibody response was studied using ELISA. A total of 30 samples were analysed for their specificity and sensitivity. Of which, 20 were positive and the sensitivity and specificity of the test appeared to be 89%. The high sensitivities, specificities and promising antigenic combination in detection of TB suggest their potential application in diagnosis of TB.
Key words: Enzyme-linked immunosorbent assay (ELISA), mycobacterial antigens, tuberculosis.
Abbreviation
TB, Tuberculosis.
