How does Mycobacterium tuberculosis infect the lung?

Tuberculosis (TB) is the most common major infectious disease today. It is estimated that two billion people--or one-third of the world's population--are chronically infected without active symptoms. Nine million new cases of active disease are diagnosed annually, resulting in two million deaths. T...

Less virulent strains of avian influenza can infect humans

The research appears in the October 1 issue of The Journal of Infectious Diseases, now available online. Crossing t...

New study shows SARS can infect brain tissue
