Pathogenesis

• Manner in which disease develops and spreads

• A type of treatment for diseases

• The study of the causes of diseases

• A method for diagnosing diseases

Adhesion

• Stage of pathogenesis in which the pathogen attaches to cells of the host

• Process of immune response activation

• Phase of pathogen replication within the host

• Mechanism of pathogen evasion from host defenses

Sterilization

• Process of removing and destroying all harmful microorganisms

• A method of cleaning surfaces with soap and water

• A technique for reducing the number of bacteria on skin

• A way to preserve food by freezing it

Anaerobic

• Requires oxygen to grow and survive

• Does not require oxygen to grow and survive

• Can grow in low oxygen environments

• Only grows in water

Virulence

• Degree of a microorganism’s pathogenicity

• The ability of a microorganism to survive in harsh environments

• The speed at which a microorganism reproduces

• The resistance of a microorganism to antibiotics

Pathogen

• Infectious agent which causes illness when multiplied inside a host

• Substance that enhances the immune response

• Non-infectious agent that promotes health

• Microorganism that is always beneficial to humans

Exposure

• Stage of pathogenesis in which the pathogen makes initial contact with the host’s body

• The phase where the immune system begins to respond to the pathogen

• The period when the pathogen replicates within the host

• The stage where symptoms of the disease first appear

Infection

• Stage of pathogenesis in which the pathogen successfully multiplies within a host

• Initial entry of the pathogen into the host

• The body's immune response to eliminate the pathogen

• The period after the pathogen has been eliminated from the host

Environment

• Surroundings which enable agent survival and transmission within the chain of infection

• A place where organisms are kept in isolation

• A method of controlling disease spread

• A type of medical treatment for infections

Modes of Transmission

• Methods agents use to move from reservoirs to hosts

• Techniques for diagnosing infectious diseases

• Types of pathogens that cause diseases

• Ways to prevent disease spread
