False-colour chest X-ray showing lobar pneumonia in the lobes of a patient's right lung (orange & yellow area at bottom of left lung on image). The disease is caused by certain strains of the bacterium Streptococcus pneumoniae. Alveoli (the air sacs of the lung) become blocked with pus, forcing air out and causing the lung to become solidified. The colouring technique highlights the effective reduction in healthy right lung (left on image) compared to the normal left lung.
