Flashcards in Lec 5-4 - Respiratory Pathogens Deck (25):
1

lower respiratory tract used to be considered blank but isnt anymore

sterile

2

most common cause of otitis media

nontypeable haemophilus influenzae then strep pneumoniae then moraxella catarrhalis

3

old questions for this section

ok

4

population most affected by otitis media

kids and immunocompromised

5

haemophilus influenze is a blank coccobacillus or pleomorphic rods

gram negative anaerobic

6

h influenzae lives in the blank resp tract

upper

7

h influenzei is blank hemolytic

not

8

h influenze is motile or not

not

9

h influenzae requires these factors for in vitro growth

x (hemin), v (nad)

10

Hib only occurs in humans and is the main cause of blank and is the main disease causing strain

meningitis

11

nontypeable H influenzae is blank which is very important

unencapsulated

12

nontypeable H influenzae can be in the lower respiratory tract of people with blank

copd

13

nontypeable cant get into the blood because it doesnt have a capsule but blank can

hib

14

nthi has a blank which causes a severe inflammatory response

LPS lipid A

15

chronic otitis media is associated with blank

biofilms

16

there is a vaccine for blank but not for blank

hib, nthi

17

causes pertussis (whooping cough)

bordetella

18

bordetella is gram blank coccobacilli and is strictly blank

negative, aerobic

19

bordetella cannot survive here and is blank growing

outside body, slow

20

two stages of pertussis

paroxysmal, convalescent

21

stage characterizied by crazy bouts of coughing with an inspiratory whoop and can lead to seizures

paroxysmal

22

convalescent stage is characterized by

declining number of lymphocytes

23

first two weeks after cough onset, best diagnostic test

culture/pcr

24

after four weeks, best test is blank

serology

25

• Know the difference between Type b and Non Typeable
• How to treat/prevent the Non typeable and disease of those two organisms
• Bordetella
o Focus on stages
o Characteristics
o Clinical symptoms
o Virulence factors
o How to treat and prevent
• There will be no questions on Moraxella
