Study reveals how tuberculosis bacteria form cords to resist antibiotics

The ability of Mycobacterium tuberculosis (MTB), a serious respiratory infection, to form snake-like cords was first noted nearly 80 years ago. In a study published October 20 in the journal Cell, investigators report the biophysical mechanisms by which these cords form and demonstrate how several generations of dividing bacteria hang together to create these structures that enable resistance to antibiotics.
