Flashcards in Gram (+) Bacilli Deck (26):
These two Gram + bacilli are aerobic and produce spores
B. cereus and B. anthracis (Bacillus)
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
What diseases does B. cereus cause?
gastroenteritis and ocular infections
What diseases does B. anthracis cause?
ANTHRAX: cutaneous, inhalation, and GI types
This Gram + Bacilli is aerobic and can be characterized by its intracellular life cycle and tumbling motility.
What diseases does Listeria cause?
NEONATES: granulomatosis, meningitis
ADULTS: flu-like symptoms, bacteremia
This Gram + Bacilli is aerobic and does not produce spores. It commonly causes erysipeloid -> cellulitis lesions and infects butchers, farmers, and vets
