Yes

PTx (pertussis toxin) and pertactin

16

M-protein, ASO

22

A-protein

Staphylococcus aureus

23

(2) Diseases causes by S. pyogenes

strep throat, scarlet fever

24

(2) virulence factors of S. pneumoniae

pneumolysin, IgA protease

25

23-valent and 13-valent vaccines available

Which one is for children?

S. pneumoniae

13-valent for children, 23-valent for adults

26

chocolate agar = Heme/NAD

30

ox+, forms biolfilms

Pseudomonas aeruguinosa

31

(2) major virulence factors of H. influenzae

OMPs and LOS

32

Morphological characteristics of Mycoplasma pneumoniae

What causes disease with this bug?

Very small, pseudomorphic, 'fried egg'

Attaches between cilia in respiratory epithelium (via P1 adhesin) -> metabolites trigger an inflammatory reaction -> inflammatory cytokines damage respiratory epithelia

33

What is P1 adhesin? What uses it?

Virulence factor used by Mycoplasma pneumoniae to attach to the respiratory epithelium.

34

Which (2) pathogens have possess a single cilia?

Pseudomonas, Legionella

35

Legionella - where is it found?

What diseases does it cause? Which one is worse?

Water supplies

Legionnaire's disease >> Pontiac fever

36

What generally only grows on buffered charcoal?

Pseudomonas aeruguinosa

37

alpha-hemolysis?

S. pneumoniae

38

What is cord factor? What uses it?

Virulence factor used by Mycoplasma tuberculosis to block PMNs.

39

Acid fast? Why?

Mycoplasma tuberculosis, due to mycolic acids in its cell wal

40

Intracellular opportunist that causes Pontiac Fever?

Legionella pneumoniae

41

Name (2) general virulence strategies employed by Pseudomonas

Forms biofilms

Toxins

42

Commonly found with cystic fibrosis

Pseudomonas aeruguinosa

43

Diseases caused by H. influenzae

pneumonia, sinusitis, otitis media, epiglottitis

44
