Demographic data, site, phenotypic and genotypic resistance of the seven resistant study isolates
| Resistance genotype | ||||||
|---|---|---|---|---|---|---|
| Isolate | Age | Country of birth | Site of TB | Drug resistance | Isoniazid | Rifampicin |
| INH=isoniazid; RIF=rifampicin; PZ=pyrazinamide. Isolates 3 and 5 had indistinguishable IS6110 types. Isolates 1 and 4 were not typable due to insufficient culture and the banding pattern of isolate 6 was uninterpretable. | ||||||
| 1 | 24 | Nigeria | Pulmonary | INH/RIF | Wild type | rpoB mutation |
| 2 | 21 | Somalia | Pulmonary | INH | katG mutation | Wild type |
| 3 | 40 | Zaire | Pulmonary | INH | inhA mutation | Wild type |
| 4 | 17 | Zaire | Pulmonary | INH | inhA mutation | Wild type |
| 5 | 20 | Zaire | Pulmonary | INH | inhA mutation | Wild type |
| 6 | 42 | UK | Pulmonary | INH | inhA mutation | Wild type |
| 7 | 44 | Somalia | Sternum | PZ | Wild type | Wild type |
