Unit 3 Project
Across
- 1. The entry, establishment, and multiplication of pathogenic organisms within a host.
- 3. the body's natural, non-specific defense system that is present from birth
- 6. A sudden and simultaneous outbreak or increase in the number of cases of disease in a community.
- 10. Route of entry for an infectious agent; typically a cutaneous or membranous route.
- 11. The ability of the body to recognize and react with multiple foreign substances.
- 16. When red blood cells burst and release hemoglobin pigment.
- 17. Decreased permeability of the walls of blood vessels in the brain, restricting access to that compartment.
- 19. A natural, nonspecific response to tissue injury that protects the host from further damage. It stimulates immune reactivity and blocks the spread of an infectious agent.
- 20. Molecules on the surface of host defense cells that recognize pathogen-associated molecular patterns on microbes.
- 22. The capacity of microbes to cause disease.
- 24. Molecules recognized by the immune system as containing foreign markers, indicating a need for immune response.
- 26. An infection that produces no noticeable symptoms even though the microbe is active in the host tissue.
- 27. Any trait or factor of a cell, virus, or molecule that makes it distinct and recognizable
- 29. The tough tri-layer membrane covering the brain and spinal cord
- 31. Immunity that is induced as a medical intervention, either by exposing an individual to an antigen or administering immune substances to them.
- 35. The chemical class of proteins to which antibodies belong.
- 38. The complete complement of microorganisms that live in or on humans.
- 41. Any deviation from health, as when the effects of microbial infection damage or disrupt tissues and organs.
- 42. Natural markers of the body that are recognized by the immune system.
- 43. A microbe capable of causing infection and disease in healthy persons with normal immune defenses.
- 44. An inflammation of the membranes (meninges) that surround and protect the brain
- 46. Communicable; transmissible by direct contact with infected people and their fresh secretions or excretions.
- 47. The state of being inactive
- 48. A system of vessels and organs that serve as sites for development of immune cells and immune reactions
- 49. A microbe’s structures or capabilities that allow it to establish itself in a host and cause damage.
Down
- 2. An infectious disease that does not arrive through transmission of an infectious agent from host to host.
- 4. Any substance that induces a state of sensitivity or resistance after processing by the immune system of the body.
- 5. Any immunity that arises naturally in an organism via previous experience with the antigen.
- 7. A person who harbors infections and inconspicuously spreads them to others
- 8. Immunity acquired through direct stimulation of the immune system by antigen.
- 9. The precise molecular group of an antigen that defines its specificity and triggers the immune response.
- 12. Cells that make up the tissues of the brain and spinal cord that receive and transmit signals to and from the peripheral nervous system and central nervous system.
- 13. Any cell, particle, or chemical that induces a specific immune response by B cells or T cells and can stimulate resistance to an infection or a toxin
- 14. Involving multiple distinct microorganisms.
- 15. Route through which a pathogen departs from the host organism.
- 18. acquired only after an immunizing event such as an infection
- 21. A period of inapparent manifestations that occurs before symptoms and signs of disease appear.
- 22. A class of white blood cells capable of engulfing other cells and particles.
- 23. A collection of monocytes and macrophages scattered throughout the extracellular spaces that function to engulf and degrade foreign molecules.
- 25. A disease afflicting an increased proportion of the population over a wide geographic area (often worldwide).
- 28. A toxin (usually protein) that is secreted and acts upon a specific cellular target
- 30. Specific resistance that is acquired indirectly by donation of preformed immune substances (antibodies) produced in the body of another individual.
- 32. Molecules on the surfaces of many types of microbes that are not present on host cells that mark the microbes as foreign.
- 33. A specific chemical product of microbes, plants, and some animals that is poisonous to other organisms.
- 34. In infection, the relative capacity of a pathogen to invade and harm host cells.
- 36. The state of damage or toxicity in the body caused by an infectious agent.
- 37. The act of taking up long-term residence; as in microbes establishing a steady relationship with a host.
- 39. In infection, ordinarily nonpathogenic or weakly pathogenic microbes that cause disease primarily in an immunologically compromised host.
- 40. The process by which microbes gain a more stable foothold at the portal of entry; often involves a specific interaction between the molecules on the microbial surface and the receptors on the host cell.
- 45. injection of whole microbes (killed or attenuated), toxoids, or parts of microbes as a prevention or cure for disease.
