H. Pylori
Proteus
Ureaplasma
Nocardia

Catalase degrades H202 into H20
(people with chronic granulomatous disease have recurrent infections with certain catalase organisms)

Nocardia
Pseudomonas
Listeria
Aspergillus
Candida
E. COli
Staph
Serratia

5

Nocardia, Pseudomonas, and Mycobacteria are examples of ____


Fusobacterium, Clostridium, Bacteroides, and Actinomyces are all what?

What antibiotics are ineffective against them?

AEROBES

Nagging Pests Must Breathe

All ANAEROBES

Anaerobes Frankly Can't Breathe Air

- Aminoglycosides are ineffective against anaerobes because these antibiotics require O2 to enter into bacterial cell

Campylobacter

12

What is the only generation of cephalosporins with activity against Bacteroides?

SECOND GENERATION
