Slide 5 - Defenses against infection Skin Chemical warfare on germs (sweat and oils produce acids that kill bacterial) Mucus membranes Stomach acids Helpful microorganisms Inflammations The immune system
Slide 6 - Weapons T-cells – cells that regulate the action of the immune system Antibodies – substances that stick to the surface of pathogens slowing their action. B-cells – cells in the immune system that produce antibodies against infection
Slide 7 - Immunization – injection of a small amount of a pathogen that will provide protection against an infectious disease. Antibiotics – drugs that kill or limit the growth of bacteria.
Slide 8 - HIV
Slide 9 - H – Human: virus can only infect humans I – Immuno-deficiency: the effect of the virus is to create a deficiency, a failure to work properly with the body’s immune system.

Slide 17 - Phases of HIV infection Infection with no signs or symptoms HIV – does not mean AIDS Signs and symptoms AIDS – T4 cells are less than 200 cells per microliter of blood or serious conditions from long-term, damage to immune system Opportunistic Infections
Slide 18 - Testing ELISA – blood test that identifies whether a person has antibodies for HIV Western Blot Test – done to confirm the results of the Elisa test.
