Journal ArticleDOI
A detailed analysis of 16S ribosomal RNA gene segments for the diagnosis of pathogenic bacteria.
TL;DR: The hypervariable sequence-specific dendrograms and the "MEGALIGN" files provided online will be highly useful tools for designing specific probes and primers for molecular assays to detect pathogenic bacteria, including select agents.
Journal ArticleDOI
Evaluation of the Analytical Performance of the Xpert MTB/RIF Assay

TL;DR: For tuberculosis case detection, sensitivity ofXpert Ultra was superior to that of Xpert in Patients with paucibacillary disease and in patients with HIV, however, this increase in sensitivity came at the expense of a decrease in specificity.
Journal ArticleDOI

TL;DR: The first demonstration of the design features and operational characteristics of an improved Xpert Ultra assay is shown, which should significantly improve TB detection, especially in patients with paucibacillary disease, and provide more-reliable detection of RIF-R.
Journal ArticleDOI
Diagnosis of Extrapulmonary Tuberculosis by Smear, Culture, and PCR Using Universal Sample Processing Technology
TL;DR: The application of USP technology, together with clinicopathological characteristics, promises to improve the accuracy and confidence of extrapulmonary tuberculosis diagnosis.
