1. infectious agent: a pathogen that can cause infection (bacteria, viruses, and fungi)
2. reservoir: natural habitat of the organism
3. portal of exit: a way for the infectious agent to escape from the reservoir in which it has been growing
4. mode of transmission: Specific ways in which microorganisms travel from the reservoir to the suseptible
host (direct, indirect, or airborne)
5. portal of entry: a way for the causative agent to enter a new reservoir or host
6. susceptible host: an uninfected person who could get sick
7. bacteria: most significant and most prevalent in hospital settings
8. Virus: smallest of all microorganisms
9. Fungi: plant-like organisms present in air, soil, and water
10. parasites: live on or in a host and rely on it for nourishment
11. sperical bacteria: cocci
12. rod shaped bacteria: bacilli
13. corkscrew shaped bacteria: spirochetes
14. gram positive bacteria: Bacteria that have a thick peptido glycan cell wall, and no outer membrane. They
stain very darkly (purple) in Gram stain.
15. gram negative bacteria: Bacteria that have a thin peptidoglycan cell wall covered by an outer plasma
membrane. They stain very lightly (pink) in Gram stain. Gram-negative bacteria are typically more resistant to antibiotics
than Gram-positive bacteria.
16. aerobic: requires oxygen to live
17. Anaerobic: can live without oxygen
18. What afffects an organisms potential to produce disease: -number of organisms
-virulence
-competence of person immune system
-length and intimacy of contact between host and organism
19. endemic: occurs with predictability in one specific area or population
20. Pandemic: Global outbreak of a new or not identifed previosly virus
21. Possible Reservoirs for Microorganisms: Other people
Animals
Soil
