TB in humans can be traced back to 9,000 years ago in Atlit Yam, a city now under the Mediterranean Sea, off the coast of Israel. Archeologists found TB in the remains of a mother and child buried together. The earliest written mentions of TB were in India (3,300 years ago) and China (2,300 years ago).

How do Koch’s postulates ensure that cause and effect of a given disease are clearly differentiated?

Koch’s postulates are as follows: The bacteria must be present in every case of the disease. The bacteria must be isolated from the host with the disease and grown in pure culture. The specific disease must be reproduced when a pure culture of the bacteria is inoculated into a healthy susceptible host.

Why do Koch’s postulates not apply to all infectious diseases?

Viruses cannot reproduce themselves, and so cannot be grown at all as a “pure culture” as Koch would have envisioned it, however it is well-established that viruses cause diseases (here and here and here). Postulates three and four also cannot be fulfilled as written if the pure culture of the disease is unavailable.
