Detection of Mycobacterium Tuberculosis DNA in Buccal Swab Samples from Children in Lima, Peru.

We examined Mycobacterium tuberculosis DNA detection from buccal swab samples collected from children in Lima, Peru. DNA was extracted and amplified via real-time polymerase chain reaction. Sensitivity was 21% (95% confidence interval [CI]: 7%-42%) in 24 culture-confirmed tuberculosis cases and 4.

Detection of Mycobacterium tuberculosis in pediatric stool samples using TruTip technology.

Background: Rapid and accurate diagnosis of childhood tuberculosis (TB) is challenging because children are often unable to produce the sputum sample required for conventional tests. Stool is an alternative sample type that is easy to collect from children, and studies investigating the use of stool for molecular detection of Mycobacterium tuberculosis (Mtb) have led to promising results. Our objective was to evaluate stool as an alternative specimen to sputum for Mtb detection in children.
