Abstract:
Dried culture spots (DCS) of inactivated Mycobacteria strains designed as part of an external quality assessment (EQA) program for the GeneXpert system has applications to other molecular tuberculosis (TB) diagnostic platforms. DCS tested on the GenoType MTBDRplus and Mycobacterium CM assays performed well with MTBDRplus version 2 but require increased bacterial concentration for use with version 1.
