TABLE 4.
Level of mycobacterial growth in the control well of the MODS-PZA reported by PZA susceptible profilea
| PZA susceptibilityb | Growth level expressed as no. (%) in control wells in a MODS-PZA assay |
||||
|---|---|---|---|---|---|
| Microcolonies | Low | Regular | High | Total | |
| Susceptible | 8 (5.59) | 13 (9.09) | 50 (34.97) | 72 (50.35) | 143 (100) |
| Resistant | 4 (10.26) | 8 (20.51) | 9 (23.08) | 18 (46.15) | 39 (100) |
| Total | 12 (6.59) | 21 (11.54) | 59 (32.42) | 90 (49.45) | 182 (100) |
a
Four levels of growth were determined according to microscopic evaluation: “Microcolonies” indicates fewer than 20 microcolonies in the well, “low” refers to a barely covered well, “regular” indicates half of the well was covered, and “high” indicates a completely covered well. No significant association (P > 0.05) was found between PZA susceptibility and the level of growth.
b
As determined by CRT.
