PATHOLOGY, INFECTION, AND DISEASE   Pathology is the scientific study of disease. It includes: 1. Etiology---the cause of the disease--disease-causing organisms are called pathogens 2. Pathogenesis---the manner in which the disease develops 3. Stuctural and functional changes brought about by the disease 4. Final effects of the disease on the body Infection---invasion or colonization of the body by pathogenic microorganisms. This term is also  used to describe the presence of normal flora organisms in an abnormal location.   Disease---an abnormal state in which part or all of the body is not properly adjusted or is  incapable of performing its normal function--change from the state of health.  These 2 terms do not mean exactly the same thing. A disease can occur without the involvement  of microorganisms. And an infection can occur without disease.   The location of microorganisms can be important.
