considered to be a nosocomial or hospital acquired infection.
What happens when there is too much immunity? - Answers - allergy
Autommune disease
Acute inflammation-sepssi, cytokine storm
What are the 3 stages of immunity? - Answers - Intrinsic
Innate
Acquired
What are the ways we prevent infection and bacteria from skin level? - Answers - Outer
layer of the skin
Normal flora
Flushing (sweat)
Phospho lipds
What are the ways we prevent infection and bacteria from the GI tract? - Answers -
Perstalisis
Low ph
Bile salts
What are the ways we prevent infection and bacteria from at the nasopharynx and eye -
Answers - mucus, saliva, tears
Flushing
Lysozye - destroy bacterial cells
What are the advantages of innate immunity - Answers - Immediate
One cell can recoginize and kill many pathogens
What are charistricts of adaptive immunity - Answers - - take effect after a few days
- leads to a state of immune memory
- Specificity improves and target the pathogen of intrest
WHY DO DOGS EAT POOP - Answers - TO REPOPULATE THEIR GUT FLORA
