Spoligotyping and Mycobacterium tuberculosis
|Mycobacteria grown in culture||No. episodes||Results of spoligotyping from clinical samples
||Results of spoligotyping from liquid medium
||Results of spoligotyping from solid medium
|Sensitivity, %§||98.2 (71.1–98.4)||91.4 (75.7–90)||100||96.8 (86.2–97)|
|Specificity, %§||95.5 (67.7–97.7)||97.7 (95.6–97.8)||93.6||95.3 (88.4–96.1)|
*Automated DNA sequencing rather than culture growth of M. chelonae confirmed one of these cases.
†Other, 1 M. fortuitum, 1 M. asiaticum, and 4 nontyped mycobacteria.
‡16 patients had ≥2 episodes of mycobacterial infections.
§Sensitivity and specificity were calculated without including the culture-negative specimens. Values in parentheses are ranges that include specimens with no growth.
