Chapters 6 & 7
Across
- 1. A severe, systemic,life-threatening allergic reaction characterized by rapidly decreasing blood pressure and respiratory obstruction
- 5. Disease-causing microbes often referred to as "germs"
- 7. Single-cell organisms enclosed within a cell wall and sometimes an outer capsule
- 9. Mode of transmission when respiratory or salivary secretions containing pathogens are expelled from the body
- 11. Immunity acquired by exposure to the antigen
- 13. Mode of transmission involving an intermediary
- 16. Mode of transmission such as touching an infectious lesion or having sexual intercourse
- 17. Signs of infection include fever, headache, fatigue, anorexia, and malaise
Down
- 2. Capacity of microbes to cause disease
- 3. Mode of transmission involving small particles from the respiratory tract that remain in the air and infect any new host who inhales the particles
- 4. Results from a deficit of any component of the immune response
- 6. Transmitted by blood, tissues, or sexual contact, not by casual contact. May be transmitted by infected mothers to infants before, during, or after birth
- 8. Type of disease that develops when antibodies form in response to self-antigens, elements of the person's cells or tissues
- 10. Signs of infection are usually those of inflammation: pain or tenderness, swelling, redness, and warmth
- 12. Respiratory infection caused by a virus that frequently mutates, preventing the development of long-term immunity in response to vaccination or infection
- 14. An intracellular parasite requiring a living host cell for reproduction
- 15. Immunity which provides only temporary protection
