2. These bacteria are resistant to several antibiotics or to all known drugs.
3. A term describing a form of antibody-antigen reaction (clumping).
5. Drugs used to fight infections against bacteria.
8. An increase in body temperature above normal range (36.6–37.2⁰C).
11. These cells confer active immunity.
13. Fever is this type of mechanism, where the body's core temperature is reset at a higher temperature.
15. An automatic, involuntary response to a stimulus (e.g. coughing, sneezing).
16. The engulfing action of leucocytes, lymphocytes and macrophages (cell eating).
19. The type of immunity given by vaccination.
20. Type of immunity that come from antibodies from another source (such as breast milk for a newborn).
23. The type of lymphocytes that produce antibodies.
26. The term for a weakened antigen in a vaccine.

1. Produced to prevent blood clotting in the localised area during inflammation.
4. Macrophages are involved in both non-specific and ________ immunity.
6. A defensive response that involves pain, redness, heat and swelling.
7. Steps taken to reduce the risk of infection by pathogens, such as handwashing.
9. The delivery of antigenic material to produce immunity to a disease.
10. Generalised scavenging cells found in connective tissue.
12. This type of vaccine uses inactivated toxins produced by the bacteria, so they don’t make a person ill.
14. The cellular part of an immune response.
17. In ___________-mediated response, B cells are stimulated to reach the lymphoid tissue.
18. This defence is the body's first line of defence.
21. Any foreign protein that enters the body.
22. The response of the body to a second or subsequent exposure to an antigen previously encountered.
24. One of the most common white blood cells involved in engulfing and ingesting foreign cells.
25. Oily secretion that creates a hostile environment for pathogens on the skin.
