Staph. Diseases Comparison Chart Flashcards
what are the five staph diseases we studied in class?
- hair follicle infections
- wound infections
- scalded skin syndrome
- toxic shock syndrome
- food borne intoxication
method of pathogenesis for hair follicle infections
invade tissue
method of pathogenesis for wound infections
invade tissue
method of pathogenesis for scalded skin syndrome
invade tissue, followed by toxin production
method of pathogenesis for toxic shock syndrome
invade tissue, followed by toxin production
method of pathogenesis for food borne intoxication
produce toxins which are then ingested, or invade tissue followed by toxin production

15-50%
Staph. aureus is hardy, it can survive in _____
dust
what is folliculitis?
pus/pain, first stage of hair follicle infection
what is furuncle?
boil/abcess, second stage of hair follicle infection
what is a carbuncle?
abscess spreads, third stage of hair follicle infection
what are the three stages of a hair follicle infection? what are their symptoms?
folliculitis: pus/pain
furuncle: boil/abscess
carbuncle: abscess spreads
pathogenesis: infects hair follicle down to subcutaneous tissue and begins to replicate.
hair follicle infections
what is the pathogenesis path of a hair follicle infection?
infects hair follicle down to subcutaneous tissue and begins to replicate –> bacteremia –> sepsis –> spread to bones/organs
how is Staph. spread in hair follicle infections?
can shed Staph. and spread it to food, patients, wounds
this condition occurs when you shed Staph. and spread it to food, patients, and wounds. what is it?
hair follicle infection
how to treat Staph.? (one word)
antibiotics!
how to treat hair follicle infections
lotions, gells, pills, minor surgery
lotions, gels, pills, minor surgery
how to treat hair follicle infections
how to prevent Staph. infections in general?
good hygiene, cover wounds, good aseptic practice
