bacteria 10-11 Flashcards
gram negative cocci
neisseria meningitidis and gonorrhea
gram positive cocci
staph and streptococci
instaphylococcus aureus, O2 can be used so
facultative anaerobe
what are the virulence factors for straphlocuccus auereus
- catalase
- coagulase
- clumping factors
- protein A
- leukocidin
- staphlukinase
- B-lactamase
- superantigens
- enterotoxins
what virulence factor for staphlyocuccus reduces potential of phagocytes to kill
(removes hydrogen peroxide produced by phagocytes)
catalase
what virulence factor for staphlyocuccus creates fibrin coat around the bacteria
coagulase
what virulence factor for staphlyocuccus is fibrinogen-binding protein and binds to ecm and foreign materials
clumping factor
what virulence factor for staphlyocuccus competes with neutrophils for Fc portion of opsonizing IgG’s
protein A
what virulence factor for staphlyocuccus deals with secretion by forming pres in membrane and major factor in pus formation
leukocidin
what virulence factor for staphlyocuccus converts plasminogen to plasmin by digesting fibrin clots and CLEAVES C3b and IgG to inhibit phagocytosis
staphlokinase
what virulence factor for staphlyocuccus is enzymatic digestion of penicillins
b-lactamase
lesions caused by staphloccus auerus
impetigo (pus and contagious)
invasive massive pus forming infections caused from staphloycoccus auerous
pyogenic infections
heat-stable (cooking doesnt help)
cause of gastrointestinal upset typically food poisoning
enterotoxins
cause loss of layers of skin
exfoliative toxin
SSSS- staph. scalded skin syndrome
