Isolates identified as mixed infections by phenotypic drug susceptibility test for rifampin versus mutation analysis in rpoB genea
| Mutation category (no. of isolates) | No. (%) of isolatesb |
ID of mixed infections (ID with secondary peak) |
||
|---|---|---|---|---|
| RIFr | RIFs | RIFr | RIFs | |
| None (74) | 8 (10.81) | 66 (89.19) | SSCM034, SC262, SSC0407, SC187 | SSC0617, SSC0619, SC240, (SC023) |
| Single (177) | 165 (93.22) | 10 (5.65) | SC107, SSC0620, (SC187, SC262) | SSC0588, SC023 |
| Multiple (41) | 39 (95.12) | 2 (4.88) | SC081 | |
a
A total of 292 isolates that were sequenced on the rpoB gene were included in this statistical analysis. Two isolates for which clinical information was lost had a single mutation. The isolates of patients whose IDs are shown in parentheses were RIF heteroresistant.
b
RIFr, resistant to RIF; RIFs, susceptible to RIF.
