And my favorite example of that occurred beginning in 1976, when it was discovered that the bacteria causing Legionnaires disease had always been present in natural waters, but it was the precise temperature of the water in heating, ventilating and air conditioning systems that raised the right temperature for the maximum reproduction of Legionella bacillus.

The ongoing sequencing of the genomes of malaria, the tubercle bacillus, leprosy, hepatitis viruses and HIV raises serious hopes of better vaccines in the future.

Moreover, the tubercle bacillus engages in trench warfare, gaining resistance to conventional antibiotics and canonical vaccination approaches, as well as delaying diagnosis and determination of drug sensitivity.

The disease is caused by a bacillus called Myobacterium leprae, first identified in 1873 by G.H. Armauer Hansen.

Indeed, his experience with the “Hegelian bacillus” made Kolakowski forever sensitive to all enthusiasms and all-encompassing creeds.
