1

For vaccines containing polysaccharide capsule antigens, a protein is conjugated to the polysaccharide antigen to ...

promote T cell activation and subsequent class switching.

2

Because a polysaccharide antigen alone cannot be presented to T cells, a vaccine without the addition of a conjugated protein would only produce what kind of antibodies?

IgM

3

What type of vaccine is Pneumovax?

Polysaccharide vaccine with no conjugated protein

4

What type of vaccine is Prevnar?

Conjugated vaccine

5

What type of vaccine is H influenzae type B?

Conjugated vaccine

6

What type of vaccine are the meningococcal vaccines?

Conjugated vaccine

7

What are the urease positive bugs?
CHuck Norris hates PUNKSS

Cryptococcus
H pylori
Proteus
Ureaplasma
Nocardia
Klebsiella
S epidermidis
S saprophyticus

8

What are the four pigment producing bacteria?

Actinomyces osrae;oo
Staph aureus
Pseudomonas aeruginoma
Serratia marcescens

9

This bug produces yellow "sulfur" granules, which are composed of filaments of bacteria.

Actinomyces israelii (isreal has yellow sand)

10

This bug produces a yellow pigment

Staph aureus (aureus means gold)

11

This bug produces a blue-green pigment

Pseudomonas aeruginosa (Aerugula is green! haha)

12

This bug produces a red pigment

Serratia marcescens (red maraschino cherries!)1

13

This virulence factor binds the Fc region of Ig, thus preventing opsonization and phagocytosis

Protein A

14

What bug expresses protein A?

Staph auerus

15

This virulence factor is an enzyme that cleaves IgA and allows bugs to colonize the respiratory mucosa

IgA protease

16

What bugs carry IgA protease?

S pneumo, HiB, Neisseria

17

This virulence factor helps prevent phagocytosis.

M protein

18

What bug expresses M protein?

group A strep
