Microbial Pathology is the study of the molecular mechanisms employed by microbes to cause sickness in humans and animals. Bacterial, protozoan, plant life and infectious agent pathogens have evolved a good form of tools to ascertain themselves within the host and gain nutrients that conjointly cause harm and sickness.
Microbial Pathogenesis is the study of the molecular mechanisms used by microbes to cause disease in humans and animals. Bacterial, protozoan, fungal and viral pathogens have evolved a wide variety of tools to establish themselves in the host and gain nutrients, which also cause damage and disease. Other mechanisms of pathogenesis include host defense evasion.
