A
B lactam positivity
22
Q
- The Dnase is good for distinguishing
A
M. catarrhalis + and Neisseria –
23
Q
- Haemophilus species that have the Para prefix only require which factor
A
V (NAD)
24
Q
- What air conditions do haemophilus need
A
5% to 7% CO2
25
* What do factor X and V mean, what organism is it referring to
Haemophilus, X= heme V= NAD
26
* Will haemophilus grow on BAP/ SBA? Choc?Why?
BAP- No growth- NAD hydrolyzes factor V, Haemophilus is not able to use it
Choc- Yes- made of boiled RBCs allowing factor X and V to release and be used
27
* Organism that is tan or brown that grows on choc, but not on MAC, SBA
Haemophilus
28
* Which Haemophilus species will demonstrate hemolysis on Horse/ rabbit BA?
H. Haemolyticus and H. parahaemolyticus
29
* Describe how the 2 haemophilus species that grow on Horse/ rabbit SB look on the plate
o Parahaemolyticus: beta light
o Haemolyticus: slightly stronger beta
30
* Explain what the porphyrin test is, what organism is it for
Detects the ability for an organism to synthesize its own
X factor with d-ALA. -produces porphobilinogen
H. parainfluenzae (+ does not need factor X) and H. influenzae (- needs but does not make a factor X), shows red orange under UV light if growing
31
* What organisms can rapid NH help ID
Haemophilus species
32
* What organism smells mousy or like bleach
Haemophilus influenzae
33
* Which strain of Haemophilus influenzae has a vaccine
B- it’s the most invasive
34
* Epiglottitis
Airway is obstructed, H. influenzae encapsulated
35
* What organism can cause a rare endocarditis after a dental procedure
