Disease And Defenses Flashcards
When neither host nor organism overrides other it is called
May be subclinical
A stalemate
How virulent a pathogen refers to its
It’s disease producing ability
Difference between innate and adaptive immunity
Innate- “non-specific”, born with
Adaptive- “specific” biological reaction acquired. Naturally occurring or artificially produced
Skin undergoes desquamation, what is desquamation
Shedding of outer layer of skin cells, replenished from inner layers
Desiccation, how this helps protect against bacteria
Removal of moisture (skin is dry, inhibiting bacterial growth)
Skin has a (low/high) pH
Low
Bodily openings are referred to as
Orifices
Some mucous membranes produce lysozymes which are
Enzyme that helps destroy bacterial cell walls
Infectious agents trigger these proteins to tell the brain to induce fever
Pyrogens
Components of the immune system
Specialized organs, WBCs, antibodies
Specialized proteins produced by body in response to antigens
Antibodies
Why Edward Jenner is important
Concept of immunity developed from his findings. (Cowpox given to people, never got small pox)
What makes a good antigen
Easily recognized as foreign, large, chemically complex, rigid/stable (doesn’t change)
When bacteria have a carbohydrate capsule they are (complex or not complex)
Not complex, harder to detect Bc repeating chains
Difference between bacteria flagella and pili
Flagella (whip like) for motility, pili for attachment
