Fundamentals of Microbiology
S K Tomar
The history of microbiology can be traced to ‘First Epidemics’ on earth, which affected Caveman and were probably waterborne. People had no real understanding of why disease occurred. As the civilization progressed, people started clustering into cities. They increasingly shared communal water, handled unwashed food, and stepped in excrement from casual discharge. The crowding increased and spread water-borne, insect-borne and skin-to-skin infectious diseases. Yet there was no general understanding of why disease occurred.
