1
Q

normal flora

A

Strains of bacteria normally present in mouth, nose, skin, and GI tract.

Limit the growth of pathogens.

Can be killed by antibiotics, resulting in opportunistic infections.

2
Q

opportunistic infections

A

Infections that occur from reduction of normal flora or in patients with compromised immune systems.

3
Q

passive immunity

A

Occurs without activation of the immune system.

4
Q

natural passive immunity

A

Conferred by maternal antibodies.

Lasts for first few months of life.

5
Q

acquired passive immunity

A

Provided by injection of immunoglobulin (antibodies) for specific disease.

6
Q

active immunity

A

Results from stimulation of immune system memory.

7
Q

natural active immunity

A

On first exposure to pathogen. May not produce s/s.

Memory B and T cells.

8
Q

induced active immunity

A

Developed through vaccination: live or weakened pathogens, or killed pathogens.

Not necessarily lifelong.

9
Q

virulent

A

Very strong and able to overcome body defenses.

10
Q

communicable disease

A

An infectious illness that can be transmitted.

11
Q

fomite

A

Contaminated intermediary surface or object.

12
Q

vector

A

Animal or insect intermediary.

13
Q

routes of infection

A
  • direct contact
  • airborne
  • STIs (chlamydia, syphillis, herpes simplex, HPV, etc)
  • bloodborne
  • GI system (HepA, HepE)
  • respiratory (Influenza, pneumonia)
  • blood and fluids (HIV, HepB, HepC, HepD, HepG)
14
Q

fulminant

A

Sudden and severe

15
Q

incubation period

A

Period between exposure and onset of s/s.

Or between periods of active disease.

16
Q

window phase

A

Period between exposure and production of enough antibodies to be detectable (aka seroconversion).

17
Q

disease period

A

Period that patient has signs & symptoms.

Ends when s/s resolve, or PT dies.

18
Q

carrier

A

PT capable of spreading disease, despite lack of s/s.

19
Q

nosocomial infection

A

Transmitted within the healthcare system.
