Flashcards in FA Gram + Rods II Deck (29):
1

Caused by Bacillus anthracis, a gram +, spore-forming rod that produces anthrax toxin.

Anthrax

2

B anthraces is the only bacterium with polypeptide capsule, which contains

D-glutamate

3

Inhalation of spores - flu-like symptoms that rapidly progress to fever, pulmonary hemorrhage, mediastinitis, and shock.

Pulmonary anthrax

4

Contact --+ black eschar (painless ulcer); can progress to bacteremia and death.

Cutaneous anthrax

5

what are the virulence factors that cause cutaneous anthrax?

Lethal factor and edema factor

6

black eschar (necrosis) surrounded by edematous ring

black skin lesions caused by cutaneous anthrax

7

Woolsorters' disease - inhalation of spores from contaminated woold

pulmonary anthrax

8

reheated rice syndrome

B cereus

9

Emetic type of B cereus is usually seen with what types of fod

rice and pasta

10

emetic type of B cereus is caused by what toxin?

cereulide, a preformed toxin

11

B cerus causes food poisoning because SPORES survive cooking rice. then keeping the rice warm results in

germination of spores and enterotoxin formation

12

how long before nausea and vomiting hit after ingestion of B cereus cereulide toxin?

1-5 hours

13

how long before B cereus diarrheal type causes watery nonbloody diarrhea and GI pain?

8-18 hours

14

Facultative intracellular microbe that is acquired by ingestion of unpasteurized milk/cheese and deli meats or by vaginal transmission during birth

Listeria monocytogenes

15

Listeria form WHAT by which they move from cell to cell

"Actin rockets"

16

characteristic tumbling motility

Listeria

17

What can listeria do to a pregnant women?

amnionitis, septicemia, spontaneous abortion

18

what can listeria do to infant/neonate?

granulomatosis infantiseptica (pyogenic all over body plus physical retardation) or neonatal meningitis

19

what can listeria do to immunocompromised?

meningitis

20

what can listeria do to healthy individuals?

mild gastroenteritis

21

how do you treat listeria gastroenteritis?

you don't - it's self-limiting

22

how do you treat listeria meningitis in infants, immunocompromised, and elderly?

ampicillin

23

what two gram positive bugs form long, branching filaments resembling fungi?

actinomyces and nocardia

24

Causes oral/facial abscesses that drain through sinus tracts, forms yellow "sulfur granules"

actinomyces

25

how to treat actinomyces?

penicillin

26

causes pulmonary infections in immunocompromised and cutaneous infections after trauma in immunocompetent

nocardia

27

how to treat nocardia?

sulfonamides

28

Branching filament that is
gram + anaerobe,
NOT acid fast,
normal oral flora

Actinomyces

29

Branching filament that is
gram + aerobe
acid fast
found in soil

Nocardia
