Pathology Infection and Disease

1. Pathology is the scientific study of disease – concerned with cause (etiology) and manner in which disease develops (pathogenesis) - Also concerned with structural and functional changes brought about by disease and final effects on the body

2. Infection – invasion or colonization of the body by pathogenic microorganisms

3. Disease – when infection results in change in state of health Normal Microbiota –
