a
MBLA of untreated sputum is a reference control to indicate the effect of NALC-NaOH treatment. P was 0.24 between the number of CFU by MGIT and MBLA of treated pellet and P was <0.01 between the number of CFU by MGIT and MBLA of untreated sputum, as determined by an independent t test. Data are for 7 replicates of sputum aliquots tested.
b
After TTP conversion.
