22
Q

A-protein

A

Staphylococcus aureus

23

(2) Diseases causes by S. pyogenes

A

strep throat, scarlet fever

24

(2) virulence factors of S. pneumoniae

A

pneumolysin, IgA protease

25
Q

23-valent and 13-valent vaccines available

Which one is for children?

A

S. pneumoniae

13-valent for children, 23-valent for adults

26
Q

Does H. influenzae have a vaccine?

A

Yes. But Hib only.

27

A

Lobar pneumonia, sinusitis, otitis media

28

29
Q

What grows primarily on chocalte agar?

What is chocolate agar?

A

Haemophilus influenzae

chocolate agar = Heme/NAD

30
Q

ox+, forms biolfilms

A

Pseudomonas aeruguinosa

31
Q

(2) major virulence factors of H. influenzae

A

OMPs and LOS

32
Q

Morphological characteristics of Mycoplasma pneumoniae

What causes disease with this bug?

A

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
Q

What is P1 adhesin? What uses it?

A

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

34
Q

Which (2) pathogens have possess a single cilia?

A

Pseudomonas, Legionella

35
Q

Legionella - where is it found?

What diseases does it cause? Which one is worse?

A

Water supplies

Legionnaire’s disease >> Pontiac fever

36
Q

What generally only grows on buffered charcoal?

A

Pseudomonas aeruguinosa

37
Q

alpha-hemolysis?

A

S. pneumoniae

38
Q

What is cord factor? What uses it?

A

Virulence factor used by Mycoplasma tuberculosis to block PMNs.

39
Q

Acid fast? Why?

A

Mycoplasma tuberculosis, due to mycolic acids in its cell wal

40
Q

Intracellular opportunist that causes Pontiac Fever?

A

Legionella pneumoniae

41
Q

Name (2) general virulence strategies employed by Pseudomonas

A

Forms biofilms

Toxins

42
Q

Commonly found with cystic fibrosis

A

Pseudomonas aeruguinosa

43
Q

Diseases caused by H. influenzae

A

pneumonia, sinusitis, otitis media, epiglottitis

44
Q

(2) bugs that cause atypical pneumonia

A

Mycoplasma pneumoniae

Pseudomonas aeruguinosa

45
Q

G-, ox+, cat+

G+, ox+, cat+

A

Neisseria meningitidis

Staphylococcus aureus
