Chemists found a way to identify a complex sugar molecule in the cell walls of Mycobacterium tuberculosis, the world's deadliest pathogen. This labeling could lead to simpler, faster TB tests.
Macrophages infected with Mycobacterium tuberculosis were fixed and imaged at four hours and 72 h postinfection. (Scale bar, 4 μm.) LAM labeling with oxaziridines persists for up to 72 h. Images are ...
