Virus
enters cell and changes DNA to create more virus cells.
Can only live in cells
Bacteria
kills nearby cells
3 shapes
Cocci, Round
Bacillus, Oblong
Spirilla, Spiral
flagellum
Can live
Systemic
whole immune system is responding

Autoclave, everything except things that can’t get wet or will melt
P, plasma (very expensive)
Cleaning
Remove visible foreign materials organic in natur
Protozoan
Rickettsial
between Virus and Bacteria
have wings and flagellum
Malaria Amoebic dysentery Tricomonus lyme disease Meningitis

Kills microorganisms and spores
Irradiation
EOG ethylene oxide gas
Autoclave
Iodine swabs
Bacteriostatic . Doesn’t clean everything
Afebrile
fever free (24 hr fever free)
Antigen
any foreign protein that triggers immune system response. i.e. pollen, virus BAD
O&P

C&S
Culture and Sensitivity
Senstivity: test for which substance kill bacteria most effectively. Largest surrounding circle indicates best response.

PRODROMAL: onset of vague symptoms
ILLNESS: Overt signs and symptoms
CONVALESCENCE: recovering
Cohorting
Deciding who gets into the room. i.e. matching pneumonia patient with chemo patient. not a good idea.
Antibody
body makes in response to exposure GOOD
it indicates level of exposure of infections
AFB
Acid Fast Bacteria
If bacteria is stained, acid wont wash off color
