Groups of patient based on the number(s) of P. aeruginosa isolates with divergent SMX-TMP MICs
| Patient groupa | No. (%) of patients withb: |
||
|---|---|---|---|
| Coexisting isolates exhibiting S/I/R SMX-TMP MICs (0.002–32 μg/ml) | Isolate(s) exhibiting S/I SMX-TMP MICs (≤3 μg/ml) | Isolate(s) exhibiting R SMX-TMP MICs only (≥4 μg/ml) | |
| Two or more isolates (n = 76) | 43 (57) | 21 (28) | 12 (16) |
| Single isolate (n = 27) | NA | 15 (56) | 12 (44) |
| All patients (n = 103) | 43 (42) | 36 (35) | 24 (23) |
a
Patients are grouped based on cultures of their respiratory secretions and the number of P. aeruginosa isolates obtained in 2007 with divergent SMX-TMP MICs using CLSI M100-S6 breakpoints.

S, susceptible, I, intermediate; R, resistant; NA, not applicable .
