[Recent advance in the isolation of mycobacteria]

Abstract

Two systems, the newly developed Mycobacteria Growth Indicator Tube (MGIT) and biphasic Septi-Chek AFB based on liquid media, proved to be significantly better than the egg-based solid media for the isolation of mycobacteria from clinical specimens. The isolation of Mycobacterium tuberculosis by MGIT occurred 8 days previous to the isolation by the conventional Ogawa method. These results indicate that the MGIT system is efficient for the recovery of mycobacteria.
