Pathogenesis is defined as the origination and development of a disease. Insights into disease etiology and progression, the two major aspects of pathogenesis, are paramount in the prevention, management and treatment of various diseases.

Why is it important to identify pathogens?

In many distinct areas of microbiology, the ability to identify microorganisms has important application. For example, in food microbiology it is important to be able to accurately identify food spoilage contaminants. In microbial ecology, the identification of microorganisms helps us characterize biodiversity.

What is pathogenesis how does it help in the study the different human systems?

Pathogenesis encompasses all the sequence of events accompanying acute and persistent infections. It includes entry of the virus into the body, multiplication and spread, the development of tissue damage, and the production of an immune response; the latter may contribute to the pathology of an infection.
