Abstract

Tuberculosis (TB) caused by Mycobacterium tuberculosis is a serious global health problem and is responsible for millions of deaths every year. For effective control of this dreadful disease, it is necessary to diagnose TB cases at the initial stages of infection. The serodiagnosis of disease represents simple, rapid and inexpensive method that can be used at the primary health care levels. In this study we have compared sensitivity of two PPE proteins of M. tuberculosis, i.e., Rv0256c and Rv1168c for their use as serodiagnostic markers in active tuberculosis patients. Employing a standardized enzyme immunoassay with these PPE proteins as candidate antigens we were able to successfully discriminate the TB patients' sera from the BCG-vaccinated healthy controls. Further, we observed that Rv1168c displayed higher sensitivity in detecting extrapulmonary and smear negative pulmonary TB cases which are difficult to diagnose by available diagnostic methods. Overall the study highlights that Rv1168c can be used as a potential serodiagnostic marker for the diagnosis of active tuberculosis disease. Copyright © 2015. Published by Elsevier B.V.
