Lec 6-3 - Streptococci Flashcards
streptococci are gram blank
positive
strep are catalase blank unlike staph
negative
strep are blank as it relates to oxygen
facultative anaerobes
strep can be classified based on blank patterns
hemolytic
clear complete hemolysis
beta
green/partial hemolysis
alpha
no hemolysis
gamma
phylogenetic analysis of blank is now used to categorize strep
16S RNA
alpha hemolytic gram positive strep that has 19 species like s mutans and sobrinus
viridians strep
viridians strep can be differentiated from strep pneumoniae because it is
optochin resistant, bile resistant, cant make insulin, no capsule
viridians strep is treated by blank
penicillin
viridians also form blank in oral cavity
biofilms
viridians can also lead to blank in the heart
strep endocarditis
strep pneumoniae are blank hemolytic, and blank/blank sensitive
alpha, optochin/bile
things that strep pneumoniae cause
acute otitis media, pneumonia, bacteremia, meningitis
strep pneumoniae is a blank coccus
diplo
strep pneumonia makes a polysaccharide blank
capsule
blank can prevent pneumococcal disease
breast feeding
pneumovax and prevnar are blank for pneumonia but only cover this many strains
vaccine, 1/4 or 1/3
group A strep is aka blank
strep pyogenes
strep pyogenes is blank hemolytic, gram blank, and grow in blank
beta, positive, chains
strep pyogenes causes these infections
strep throat, scarlet fever, impetigo, cellulitis
strep pyogenes causes these invasive infections
bacteremia, toxic shock, necrotizing fasciitis
post infectious sequelae of strep pyogenes
rheumatic fever, glomerulonephritis
