Immunopathology 2 Flashcards
Type II/III Hypersensitivity
Autoimmune Rxns
Type II
- Body attacks itself; forms antibodies against itself
- Ex: RA, DM, MS
Type III
- Blood transfusion incompatibility, hemolytic disease of the newborn
- Ex: Rh factor diff between mom and baby
Type VI Hypersensitivity
Delayed or cell-mediated response
- Ex: TB test, poison oak, organ transplant rejection
How does vaccination protect us from disease?
- Introduces dead or weakened antigen to body
- Body produces antibodies against antigen
How does exercise effect the immune response?
- Increased release of WBC, endorphins
- Improves pain response and sleep patterns
- Decreases depression
How does exercise effect the immune response?
Good:
- Increased release of WBC, endorphins
- Improves pain response and sleep patterns
- Decreases depression
Bad:
- Long duration high intensity can have neg effect due to stress hormone cortisol and adrenaline that suppress immune system

Good:
- Increased release of WBC, endorphins
- Improves pain response and sleep patterns
- Decreases depression
- Up to moderate intensity is good
Bad:
- Long duration high intensity can have neg effect due to stress hormone cortisol and adrenaline that suppress immune system
What is nosocomial infection and how is it prevented?
Healthcare associated infections
Prevented by using universal precautions
(Hand washing, gloves, gowns, masks, eye protection, use sterile techniques for wound care)

Name the various ways infections diseases are transmitted
- Air transmission (cough sneeze)
- Contact transmission (bodily fluids/open wound)
- Ingestion (eat/drink)
- Direct contact with pathogen
- Vector (from a bug)
Name and describe 3 common infective microorganisms.
- Bacteria: single cell organism
- Virus: invade host, mutate fast
- Fungi: mold, yeast; require warm/moist area
What is MRSA? What has caused its increased prevalence?
MRSA:
Methicillin Resistant Staphylococcus Aureus
- Over Rx of antibiotics
- Pts not completing dosage of antibiotics
- Use of antibiotics in food products
