The Body’s Natural Defenses
Tears (eye, lysozymes) Coughing Sneezing Urinating Intact Skin Cilia (respiratory system) Vomiting Diarhhea Gastric pH
Virus
enters cell and changes DNA to create more virus cells.
Can only live in cells
Bacteria
kills nearby cells
3 shapes

Bacillus, Oblong
Spirilla, Spiral
flagellum
Can live
Local
abcess
wound
Swelling (TUMOR)
Redness (RUBOR)
Heat (CALOR)

Neg Pressure Room
Used for airborne illness i.e. TB cause by mycobacterium.
TB
Most common airborne bacteria
Mycobacterium
Bacteriostatic
Hold bacteria count still
Types of Sterilization
R, irradiated
EO, ethylene oxide gas
Autoclave, everything except things that can’t get wet or will melt
P, plasma (very expensive)
How does a virus infect
It enters the cell and changes the DNA making cells create more viruses.
Can only live in other cells
Cultures
Test for bacteria in the body.
Bacteriocidal
Kills bacteria
Disinfection
Destroy microorganisms
Alchohol
Iodine
Chlorine bleach
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
C&S
Culture and Sensitivity
Senstivity: test for which substance kill bacteria most effectively. Largest surrounding circle indicates best response.
Sterilization
Kills microorganisms and spores
Irradiation
EOG ethylene oxide gas
Autoclave
O&P
Ova and Parasite test
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
Mortality
Death
Morbidity
Sickness
