These tiny needle felted lungs are made from wool and household dust impregnated with the extracted DNA of killed Mycobacterium tuberculosis (TB). The organisms have been rendered sterile using a validated process used in whole genome sequencing of TB. The lungs show various stages of the disease and forms of treatment. Around the turn of the 20th Century it was widely believed that household dust was one of the main transmission vectors. Sufferers would cough up sputum from their lungs and spit it out. The sputum would dry and become mixed with dust. But it seems very unlikely that the disease could be spread effectively in this manner, as the particles are far too large.
