rutgers and NDI in brazil. TB being a disease that still plagues much of the world. study in mice. higher transmission rate bacteria apparently form globs in the lungs that break up and get expelled through mouth and nose. lower transmission rate strain is attacked by immune system in different way and location in lungs, and does not leave the lungs at the same high rate. paper is not very readable to layperson. didnt glean where they might go next with this information.


study in mice not clinical? know many with TB positive skin tests and granulomas in brazil who are not contagious yet paper describes highly infectious strain as developing granulomas. seems contradictory to layperson.
