History and scope of Microbiology The hypothesis that living organisms arise from nonliving matter is called spontaneous generation. Infection is the presence of microorganisms causing damage to body tissues, usually in the presence of acute inflammation (pain, swelling, redness, heat and loss of function). Active disease many years later(reactivation disease). – A pathogen that causes a specific disease is the agent. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities.
