Tetrazolium Microplate Assay as a Rapid and Inexpensive Colorimetric Method for Determination of Antibiotic Susceptibility of Mycobacterium tuberculosis

摘要

The emergence of multidrug-resistant tuberculosis underscores the need for low-cost, rapid methods to determine the susceptibility of Mycobacterium tuberculosis to antibiotics. A new, rapid, easily read, and inexpensive colorimetric method with a tetrazolium indicator performs this determination as quickly and accurately as the more expensive Alamar Blue technique.
