Deebs Micro Week 1 Flashcards
dextran production
strep viridans-for glycocalyx formation
SdrG
staph epidermidis
T4SS
Rickettsia rickettsia-attaches to host cell and tricks host cell into engulfing it-because it is an obligate intracellular parasite
CAR
coxsackie-adenovirus receptor
FimA and GspB
Surface adhesion proteins for strep viridans
Which organisms have capsules?
strep pneumo
strep pyogenes
neisseria meningitidis
staph aureus
Which organisms do biofilm formation?
enterococcus species
staph aureus
staph epidermidis
OmpA and OmpB
Rickettsia Rickettsia for adherence
FnbpA
Staph aureus: Fibronectin bindin proteins
Coagulase
Staph aureus
Which bugs are beta hemolytic?
staph aureus and strep pyogenes
which one is alpha hemolytic?
Strep viridans
How is echovirus transmitted?
Fecal to oral
M protein
virulence factor of strep pyogenes-prevents phagocytosis-antibodies are then made against it and they cross react with meromysin of the heart
Streptokinase
Strep pyogenes: cleaves plasminogen to plasmin, dissolves clots!
Streptolysin S and O
WBC and RBC lysis via pore formation
Causes of pericarditis
Coxsacie A, B, and echovirus
Causes of myocarditis
Coxsackie B and adenovirus
what is common in summer months?
pericarditis (echovirus)
Tx for RMSF?
Doxy
Characteristics of Coxsackie A & B?
Virus \+ssRNA (group IV) nonsegmented icosahedral nucleocapsid nonenveloped Picornaviridae enterovirus
2 major duke criteria
evidence of endocardial involvement
2 + blood cultures
triad for RMSF?
fever
rash
headache
most common cause of acute endocarditis?
staph aureus
