Overview
Microbiology cellular microbiology and pathogenesis is the study of the structure and function of microorganisms, their interaction with the larger biosphere, and the response of the host to infection. It is a subfield of microbiology focused on the mechanisms of pathogenesis, the process by which organisms cause disease. It includes the study of microbial physiology and genetics, cellular responses to infection and the role of microbes in the development and maintenance of host immunity. This is a rapidly advancing field with insight into how microorganisms interact with hosts to cause disease, and the potential therapeutic interventions to prevent and treat infection. It has significant implications for public health, biotechnology, and the development of new technologies for diagnosis and treatment of disease.
