Germ Theory of Disease is a theory in
biology which tells us that diseases are not spontaneously generated but caused by
micro-organisms / microbes, commonly known as 'germs'. These germs multiply to cause and
aggravate diseases in living beings. This theory is taken to be the cornerstone of
medicine and microbiological researches, leading to innovations in the field of
anti-biotics.
It was Louis Pasteur who discovered that most
infectious diseases are caused by 'germs'. He also invented the immunizing method,
Pasteurization, named after him. Of course, in
Atharvaveda, an old Hindu sacred text, it was told that diseases
are due to living causative agents such as yatudhanya, kimidi, krimi
and durnama.Since Pasteur and his successors like Koch
and Flemming the theory has been a great contribution to modern medicine and
microbiology, a refutation of the idea of spontaneous
generation.
