Identify the basis of vaccination and how immunity can be acquired both actively and passively. Infection: invasion and multiplication of microorganisms in body tissues, especially that causes local cellular injury due to competitive metabolism, Chronic: long duration, of the order of weeks or months. Acute: short duration, of the order of several days. Primary pathogen: the presence of this pathogen causes the disease and their intrinsic virulence. Opportunistic pathogen: requires a depressed immune response (e. g. tb) Easy transmission, communicable disease, by an ill persons secretions (e. g. influenza) Vaccination: physical injection of the inactivated or weakened pathogen.
