- <p>Tuberculosis sufferers are getting glowing help from the firefly
- </p>
- <p> Using current techniques, doctors must wait up to 18 weeks
- for laboratory results to identify which drugs effectively treat
- strains of tuberculosis. Now scientists have come up with an
- ingenious assay that promises to cut that time in half--literally by shedding a new light on TB. Their bright new idea
- comes from the same gene that makes fireflies glow.
- </p>
- <p> In a report to Science, researchers at the Albert Einstein
- College of Medicine say they insert the gene, which directs
- production of a light-emitting enzyme called luciferase, into
- tissue samples taken from TB patients. Within two hours, the
- cultures are aglow. Various drugs are then introduced. If the
- particular strain of TB is susceptible, the light dims and goes
- out. If the TB is resistant, the culture keeps shining.
