Flashcards in Lec 6-3 - Streptococci Deck (35):
1

streptococci are gram blank

positive

2

strep are catalase blank unlike staph

negative

3

strep are blank as it relates to oxygen

facultative anaerobes

4

strep can be classified based on blank patterns

hemolytic

5

clear complete hemolysis

beta

6

green/partial hemolysis

alpha

7

no hemolysis

gamma

8

phylogenetic analysis of blank is now used to categorize strep

16S RNA

9

alpha hemolytic gram positive strep that has 19 species like s mutans and sobrinus

viridians strep

10

viridians strep can be differentiated from strep pneumoniae because it is

optochin resistant, bile resistant, cant make insulin, no capsule

11

viridians strep is treated by blank

penicillin

12

viridians also form blank in oral cavity

biofilms

13

viridians can also lead to blank in the heart

strep endocarditis

14

strep pneumoniae are blank hemolytic, and blank/blank sensitive

alpha, optochin/bile

15

things that strep pneumoniae cause

acute otitis media, pneumonia, bacteremia, meningitis

16

strep pneumoniae is a blank coccus

diplo

17

strep pneumonia makes a polysaccharide blank

capsule

18

blank can prevent pneumococcal disease

breast feeding

19

pneumovax and prevnar are blank for pneumonia but only cover this many strains

vaccine, 1/4 or 1/3

20

group A strep is aka blank

strep pyogenes

21

strep pyogenes is blank hemolytic, gram blank, and grow in blank

beta, positive, chains

22

strep pyogenes causes these infections

strep throat, scarlet fever, impetigo, cellulitis

23

strep pyogenes causes these invasive infections

bacteremia, toxic shock, necrotizing fasciitis

24

post infectious sequelae of strep pyogenes

rheumatic fever, glomerulonephritis

25

there are many strep blank factors

virulence

26

virulence factor that has 100 M types and involved in mucosal infection but is less important during bacteriemia/sepsis.... anti phagocytic and adherence

M protein

27

one of the most important virulence factors that causes toxic shock and scarlet fever

pyrogenic exotoxins

28

group b strep is aka blank

strep agalactiae

29

strep agalactiae is normal in blank and blank

intestinal/genital tracts

30

strep agalactiae is diagnosed by secreting blank and causes blank in presence of staph aureus

cAMP, beta hemolysis

31

group d strep is now called blank

enterococcus

32

enterococcus are blank in the human gut

commensals

33

enterococcus are blank hemolytic and diplococcus

gamma

34

enterococcus are blank resistant to antibiotics

intrinsically

35

enterococcus survive in blank conditions

harsh
