Multidrug-resistant tuberculosis (MDR-TB) has a worse prognosis if patients are resistant to fluoroquinolones, new analysis suggests.

A new interferon-gamma release assay (IGRA) for diagnosing tuberculosis performs as well as an earlier test, but uses only a third of the blood, researchers have found.

When induced sputum and culture are not available, nasopharyngeal specimens may be used for rapid molecular diagnosis of pulmonary tuberculosis in children, a new study shows.

The interferon-gamma release assay (IGRA) is more specific, at least as sensitive, and may better predict disease progression than the tuberculin skin test in pregnant women at risk of exposure to tuberculosis, according to a report this month in Obstetrics & Gynecology.
