Your comment will be reviewed and published at the journal's discretion. Clinical diagnosis lacks standardization, and traditional and molecular microbiologic methods lack sensitivity, particularly in children. The current methods for detecting Mycobacterium tuberculosis (Mtb) are not clinically optimal. Many of these can be isolated from humans, although many are found in the environment.
