These can cause bronchitis and pneumonia. The blue, green & red bodies represent bacilli (rod-shaped bacteria) such as the organisms which cause tuberculosis and whooping cough. Here, the right bronchus is cut away revealing inflammation & infected sputum and pus (yellow). Pus is also present in the lobes of the lung (pneumonia).
