Test #3 Flashcards
Microorganisms including bacteria, viruses, fungi, and protozoa
Infectious agents
Requires oxygen for survival and for multiplication sufficient to cause disease
Aerobic Bacteria
Individual’s degree of resistance to pathogens- depends on a person natural defenses and strength and # of microorganisms
Susceptible host
Anaerobic Bacteria
Thrives with little or no free oxygen
Portal of Exit
Includes sites such as blood, skin, mucous membranes, respiratory tract, GI tract.
Asepsis
Absence of pathogenic (disease producing) microorganisms
Port of Entry
Route the microorganism enters the body- similar to the port of exit.
Modes of Transmission
Specific way of being transmitted via contact, droplet, airborne, and other vehicles or vectors
Place where microorganisms survive, multiply, and await transfer to a susceptible host
Reservoir
Is inflammation a positive or negative response? Specific or non-specific?
Positive and non-specific
What type of immunity is inflammation classified as?
Natural immunity
List the cell response mechanisms to inflammation and their normal lab values
- Elevated WBC (Leukocytes) = 5,000-10,000
- Elevated Neutrophils = 55-70%
- Elevated ESR = 15/hr (m) 20/hr (f)
- Elevated CRP = 1-3 mg/dL
What are the 5 manifestations of inflammation?
- Warmth
- Erythema
- Swelling (phagocytosis)
- Pain
- Decreased fx/movement
Localized vs. Systemic signs/symptoms of Infection
Localized = pain, tenderness, erythema Systemic = fever, lymph node enlargement, diarrhea, malaise.
Vehicles vs. Vectors
Vehicles = contaminated items (blood, food, etc.) Vectors = animals that transmit (ticks, mosquitoes, etc.)
