Tubercle n.

This is composed of a hard, grayish, or yellowish, translucent or opaque matter, which gradually softens, and excites suppuration in its vicinity. It is most frequently found in the lungs, causing consumption.

Tubercle bacillus (Med.), a minute vegetable organism (Mycobacterium tuberculosis, formerly Bacillus tuberculosis, and also called Koch's bacillus) discovered by Koch, a German physician, in the sputum of consumptive patients and in tuberculous tissue. It is the causative agent of tuberculosis.
