There was no sputum conversion at the end of the Intensive phase and rifampicin resistance was detected in Gene Xpert (Line probe assay revealed resistance to rifampicin and Isoniazid with KatG mutation). On this regime, cultures grew MTB and the sensitivity test(DST) reveale...

For GeneXpert, the presence of susceptible bacteria would result in the occurrence of amplification curves, thereby resulting in missed detection of RIF heteroresistance. A prior study has demonstrated that a high melting curve assay can detect the presence of RIF resistance mutations down to a ...
Recruiters will engage with potential participants who have laboratory confirmation of TB with positive sputum GeneXpert and who either have yet to initiate TB treatment or who have taken less than three doses of TB treatment at the time of screening, for this episode of TB disease. Patients di...
TBCh was made in 11 pleural and 25 LN specimens. Mutations in rpoB gene were found in seven (63.6%) pleural and in 16 (64.0%) LN samples. Mutations leading to DR to H were found in 15 (60.0%) samples from LN and in eight (72.7%) pleural biopsies. DR to H was associated with ...

• 优点: ▫ 早期&快速发现耐药情况 ▫ GeneXpert: 容易操作,对生物安全的要求较低 • WHO 2011 MDR-TB治疗指南: 建议1: 利用现有资源,推荐开展异烟肼和利福平或者利福平快速药敏试验, 以替代传统试验或者在诊断结核时不进行药物敏试验的模式。
One success story, Cohn said, was the development, licensing and rapid endorsement by WHO of the GeneXpert MTB/RIF (Cepheid) assay to rapidly diagnose TB and RR-TB, which he has called the biggest breakthrough for TB diagnosis in decades. The molecular test provides a rapid and sensitive ...
Currently available molecular assays have the advantage of rapidly detecting resistant strains of MTB, but the GeneXpert does not detect isoniazid (INH) resistance and the GenoTypeMTBDRplus(LPA) assay may underestimate resistance to INH. Increasing proportions of rifampicin mono-resistance resistance (...
cities of the country as a part of its implementation research projects by using Genexpert to pick up TB and Multi-Drug Resistant TB (MDR TB). Genexpert test is a molecular test which detects the DNA in TB bacteria. It uses a sputum sample and can give a result in less than 2 hours...
