Sepsis Lecture Flashcards
metastatic lesions are a sign of what
septicemia
fever, rash, hypotension are signs of
shock
drug used against penicillin resistant staph
vancomycin
drug used against methicillin resistant staph
vancomycin
drug used against vancomycin resistant staph
oxolidinones (linezolid)
strep species involved in the normal oral microbiota
Streptococcus mutans
what protein involved w/ S. pyogenes is responsible for sequelae of RF and glomerulonephritis b/c it binds factor H and disrupts complement
M protein
what provides evidence of a previous Strep infection
high antistreptolysin O titers
hemolysin of strep that lyses blood anaerobically
Streptolysin O
strep exotoxins cause what through cytokine storm
toxic shock like syndrome (septic shock)
sx’s include confluent rash and strawberry tongue
scarlet fever
drug used to treat GAS
penicillin
drug used to treat syphillis
penicillin G
drug/s used to treat Group D strep
syngery b/t ampicillin and aminoglycoside
fever, altered mental status, hypotensive, petechial rash
Neisseria meningitis
gram - diplococci (kidney bean shape); oxidase +
Neisseria
what type of N. meningitis resembles K1 capsule of E. coli
type B
endotoxin (lipid A-LOS), carbohydrate capsule, pili, exotoxin cleaving IgA are virulence factors of
N. meningitis
what interaction activates clotting factors
lipid A binding to TLR4
usually starts as sore throat and is found in closed populations
N. meningitis
2 outcomes of meningococcemia:
gradual-sepsis
fulminating- clotting factors increased
petechiae and multisystem organ failure are signs of this
Disseminated intravascular coagulation
