Across
- 2. Immunity Specific immune defense mechanisms. This form of immunity is acquired over a lifetime and uses antibodies to respond to specific antigens.
- 3. An epidemic that has spread across several countries or continents and affects a large number of people.
- 6. A single-celled, prokaryotic microorganism.
- 11. A type of lymphocyte (white blood cell) that matures in the bone marrow and produces antibodies.
- 12. A large, eukaryotic, multicellular, parasitic worm, such as a tapeworm, liver fluke, ascarid, or leech.
- 14. Saprophytic, and parasitic spore-producing eukaryotic organisms that lack chlorophyll, such as molds, rusts, mildews, smuts, mushrooms, and yeasts.
- 16. Contact Disease transmission that occurs when a susceptible host inhales infected particles, touches an infected object or is bitten by an infected insect.
- 19. A protein produced by B cells in the blood; works to impair pathogens.
- 24. Immunity Non-specific immune defense mechanisms that we are born with. These mechanisms work to keep anything outside of us from coming in.
- 27. A scientist who investigates the growth, structure, development, and other characteristics of microorganisms, such as bacteria.
- 28. A type of white blood cell (lymphocyte) produced by the thymus and involved in the immune response.
- 29. An organism in which another organism lives.
- 30. Any of a large group of nonliving, submicroscopic infective agents that typically comprise an RNA or DNA core of genetic material surrounded by a protein coat. Viruses are not cellular and require a host in which to replicate.
- 31. Anything that stimulates an immune response.
- 32. A sudden increase in the occurrence of a disease in a localized area.
Down
- 1. Refers to having a disease or a symptom of disease, or the rate of disease within a population.
- 4. Any of various infectious proteins that are abnormal forms of normal cellular proteins.
- 5. A disease present in a community or population within a specific geographic area.
- 7. The establishment of a disease-causing microorganism within a host.
- 8. Contact Disease transmission that occurs when a susceptible host touches an infected individual or is exposed to their body fluids.
- 9. A disease-causing organism.
- 10. Any spherical, or generally round, bacterium.
- 13. Any eukaryotic protist of the phylum or subkingdom Protozoa.
- 15. The ability to defend against a pathogen by preventing its entry and/or development or by neutralizing its pathogenic cellular products.
- 17. A spiral-shaped bacterium.
- 18. technique The practice and/or process of preventing contamination.
- 20. A disorder of structure or function in an organism that results in specific signs or symptoms, may affect a specific location in the organism and is not a direct result of physical injury.
- 21. A substance used to stimulate an immune response with the goal of creating antibodies and providing immunity to specific infections.
- 22. streak The process by which bacteria are streaked onto a plate to form isolated colonies
- 23. They investigate health-related matters such as disease, outbreaks, and chronic illnesses by gathering information, examining data, and looking for patterns.
- 25. A rod-shaped (cylindrical) bacterium.
- 26. Refers to the number of deaths in a certain group of people in a certain period of time.
- 27. The chemical reaction processes of breaking down molecules for energy and of using simple building blocks to build up more complex molecules needed for growth and repair.
