Abstract
Tuberculosis (TB) remains as a major public health issue in developing countries. Accurate detection is essential for the proper management of patients with active disease. Here, we present a simple DNAzol-LAMP (loop-mediated isothermal amplification) procedure for the detection of Mycobacterium tuberculosis in sputum specimens. Twenty smear-positive sputum samples were analyzed as follows: (i) Genetic material was extracted by a standard DNAzol protocol, and (ii) mycobacterial DNA was detected by a typical TB-specific loop-mediated isothermal amplification method. Results and diagnostic test performance attests to the suitability of the proposed procedure.
