Chapter 15 disease

4. infectious disease that can be passed human to human
5. become infected, disease slow progressing, pathology occurs over long time
7. cause disease regardless of the host's microbiota or immune system status
9. disease acquired in a hospital setting
12. patient is feeling ill. microbe gets to peak, then starts to decline
15. can only cause disease in situations that compromise host's defenses
16. the number of microbes needed to cause infection in 50% of inoculated animals
18. how well the pathogen causes disease
20. disease contracted by a medical procedure

1. first signs or symptoms of disease. microbe is still increasing
2. disease caused by a pathogenic microbe
3. time from infection to first symptoms of disease. microbe is multiplying
5. patient is recovering. timing is variable
6. subjective feelings of disease
8. become infected, become diseased, recover
10. disease transmitted from animals to humans
11. signs and symptoms start to abate. microbe is being cleared by immune system
13. become infected, disease may be delayed, microbe goes dormant
14. objective or measurable indications of disease
17. ability of a microbe to cause disease
19. the number of microbes needed to cause lethal infections in 50% of inoculated animals
