Flashcards in Infectious Disease 5 Deck (29):
1

Specific types of bacterial diseases

- Clostridium dificile
- Staphylococcal infections
- Group A streptococci
- Group B streptococci
- Gas gangrene (Clostridial myonecrosis)
- Pseudomonas aeroginosa

2

prevalence of clostridium dificile

~200/100,000 people

3

Why is clostridium dificile more prevalent in hospitals?

high rate of antibiotic use in hospitals

4

transmission of c-diff

- fecal-oral
- contaminated environment

5

c-diff and alcohol based hand sanitizers

not effective

6

What increases the risk of a c-diff infection?

- age
- GERD tx

7

GERD tx

- H2 receptor blocker
- proton pump inhibitors

8

How does a c-diff infection happen in the body?

overgrowth of c-diff bacteria when other intestinal flora are destroyed

9

tx for c-diff

- fecal transplants
- Flagyl

10

Flagyl is effective against these types of bacteria

anaerobic

11

Examples of staphylococcal infections

- S. aureus
- S. epidermis

12

Staphylococcal infections are spread via

- direct contact
- multiple predisposing factors

13

results of a staphylococcal infection

- infection
- suppuration
- abscess
- infective syndromes

14

tx for MRSA, VISA

vancomycin

15

tx for VRSA

- daptomycin
- linezolid

16

Examples of group A streptococci

- GAS
- S. pyogenes

17

group A streptococci spread by

- droplets
- direct contact

18

Group A streptococci include multiple diseases such as:

necrotizing fasciitis

19

Example of a group B streptococci

S. agalactiae

20

leading causes of group B streptococci infections

- pneumonia
- meningitis
- sepsis

21

Group B streptococci and women

- part of normal vaginal flora
- found in 30% of women

22

tx of gas gangrene (aka clostridial myonecrosis)

- debridement and excision of necrotic tissue
- IV antibiotics
- possible HBO therapy

23

Major opportunistic pathogen and one of the most common nosocomial infections

pseudomonas aeruginosa

24

How is pseudomonas spread?

- contact
- not common in community-acquired infections

25

Where are pseudomonas aeruginosa pathogens found?

- moist areas (sinks)
- healthcare workers' hands
- fingernails

26

Pseudomonas: common conditions where it's found

- pneumonia
- wounds
- UTI
- sepsis
- chronic lung disease

27

local pseudomonas infection mgmt

fairly easy to manage

28

Septicemia mgmt

high mortality rate

29

Characteristic features of a pseudomonas infection

- sweet odor
- light green tinge to wound
