Flashcards in Gram (+) Bacilli Deck (26):
1

These two Gram + bacilli are aerobic and produce spores

B. cereus and B. anthracis (Bacillus)

2

One way to differentiate between B. cereus and B. anthracis is to look at hemolysis and motility. Describe these two characteristics for both.

B. cereus: beta-hemolytic, motile

B. anthracis: non-hemolytic, non-motile

3

What diseases does B. cereus cause?

gastroenteritis and ocular infections

4

What diseases does B. anthracis cause?

ANTHRAX: cutaneous, inhalation, and GI types

5

This Gram + Bacilli is aerobic and can be characterized by its intracellular life cycle and tumbling motility.

Listeria

6

What diseases does Listeria cause?

NEONATES: granulomatosis, meningitis
ADULTS: flu-like symptoms, bacteremia

7

This Gram + Bacilli is aerobic and does not produce spores. It commonly causes erysipeloid -> cellulitis lesions and infects butchers, farmers, and vets

Erysipelothrix rhusiopathie

8

This Gram + Bacilli is aerobic and does not produce spores. It is characterized by looking like chinese characters and formation of a dark pseudomembrane.
