sign
objectively observable indication of disease or disorder
types of bacteria
- Diplococci
- Staphylococci
- Streptococci
- Bacilli
- Spirochetes
- mycoplasma
diplococci
single cell microorganism - paired cocci - pneumonia
staphylococci
clump together like grapes - methicillin-resistant staphylococcus aureus MRSA
streptococci
chain together - strep throat, rheumatic fever, necrotizing fasciitis
bacilli
elongated, rod-shaped - most capable of forming spores
spirochetes
spiral - syphilis, Lyme disease
myoplasma
tiny microorganisms - some sexually transmitted infections
antiseptic
anything that prevents infection
disinfection
destroys pathogens by exposure to chemical or physical agents
potentially infectious body fluids
semen, vaginal secretion, breast milk, and blood
purpose of inflammation
to protect body, limit range & prepare for healing
inflammation cellular activity
endothelial cells - activate platelets
platelets become jagged and sticky weave net of fibrin with proteins to form blood clots
Final cleanup stage - monocytes and macrophages clean up debris prep for healing
injured cells release factors that form pro-inflammatory chemicals of
- prostaglandins
- leukotrienes
- C-reactive protein
stages of healing
- acute - inflammation stage vasoconstriction, dilation, edema 1-3 days
- subacute - endothelial cells grow into new capillaries 2-3 weeks
- post-acute - remodeling, scar tissue
- chronic - pus is not reabsorbed
anti-inflammatories & massage
schedule session when drug is at its lowest activity to get most accurate feedback
CDC recommended disinfectant
10% bleach solution for high-touch surfaces
