Obligate aerobes

Nagging pests must breathe

Nocardia, pseudomonas, mycobacterium TB.

Reactivation of mycobacterium TB after immune compromise or TNF-alpha inhibitor use has a prediliction for the apices of the lung which has the highest po2.

1

Obligate anaerobes

Actors back in the closet can't breathe.
Actinomyces, bacteroides, clostridium.

These bacteria lack catalase and / or superoxide dismutase and are sensitive to oxidative damage.
Generally foul-smelling and are difficult to culture.
Produce gas in tissue (co2 and h2)

Aminoglycosides are ineffective against anaerobes because the antibiotics require o2 to enter into bacterial cell

2

Which antibiotics require oxygen to enter into the bacterial cell?

Aminoglycosides

3

Obligate intracellular bateria

My cells are RiCh in bacteria
Rickettsia, chlamydia

4

Facultative intracellular

Nice salmon bring my french legion your list

Neisseria, salmonella, brucella, mycobacterium, francisella, legionella, yersinia pestis, listeria

5

Encapsulated bacteria

Clumsy Sam collapsed on his SHIN B-Side the capsule

Klebsiella
Salmonella
E coli
Shin - Strep pneumo, H flu B, Neisseria meningitidis
Group B strep

Encapsulated bacteria are opsonized, then cleared by the spleen. Asplenics have decreased opsonizing ability and are at risk for severe infections. Give s pneumo, h flu, and n meningitidis vaccines.

6

Catalase positive organisms?

The cat aspirated pseudofed and listerine but survived to eat candy and other stuff

Aspergillus
Pseudomonas
Listeria
Serratia
E coli
Candida
S aureus

Catalase degrades H2O2 before it can be converted to microbicidal products by the enzyme myeloperoxidase. People with chronic granulomatous disease (NADPH oxidase deficiency) have recurrent infections with catalase positive organisms.

7

Encapsulated bacterial vaccines

SHIN -
PCV - prevnar - pneumococcal conjugate vaccine
PPSV - no conjugate protein
H flu B - conjugate vaccine
Meningococcal vaccine - conjugate vaccine

8

Urease positive bugs

The prostitute noticed cryptic piles of skin, urine, sap at the club

Proteus
Nocedia
Cryptococcus
H pylori
Ureaplasma
S saprophyticus
S epi
Klebsiella

9

Pigment that actinomyces israelii produces

Israel has yellow sand - yellow

10

S aureus

Yellow

11

Pseudomonas aeruginosa

Blue-green pigment

12

What are the oxidase positive organisms?

Legions at Camp Pile More Coal (on the fire to make) Nice Ox Soup.

Legionella
Campylobacter
H pylori
Moraxella
Cholera
Neisseria
Oxidase positive
Pseudomonas
