The performance of the immunochromatographic assay, SD BIOLINE TB Ag MPT64 RAPID®, was evaluated in Madagascar. Using mouse anti-MPT64 monoclonal antibodies for rapid discrimination between the Mycobacterium tuberculosis complex and nontuberculous mycobacteria, the kit was tested on mycobacteria and other pathogens using conventional methods as the gold(More)

To improve the diagnosis of tuberculosis (TB), more rapid diagnostic techniques such as antibody detection based on immunochromatographic methods were developed. The objective of this study was to evaluate the performance of the SD Rapid TB kit for the diagnosis of active TB with serums from patients and close contact controls in Antananarivo, Madagascar.(More)
Tuberculosis (TB) is a bacterial disease caused by organisms of the Mycobacterium tuberculosis complex (MTC). The definitive diagnosis of TB depends on the isolation and identification of the etiologic agent. Clinical identification of mycobacteria remains difficult and timeconsuming. Cultures in specific media can result not only in M. tuberculosis (MTB)(More)
