Lay Description

Tuberculosis is an infection that primarily affects the lungs and causes fever and weight loss. While some people exposed to the tuberculosis (TB) bacteria develop the disease others do not. An important step in our understanding of these different responses is to measure the response of immune cells to infection with the TB bacteria. This study will request blood to be collected from healthy individuals and individuals who have had a positive test result for TB.
