Flashcards in FA Basic Bacteriology II Deck (18):
For vaccines containing polysaccharide capsule antigens, a protein is conjugated to the polysaccharide antigen to ...
promote T cell activation and subsequent class switching.
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?
What type of vaccine is Pneumovax?
Polysaccharide vaccine with no conjugated protein
What type of vaccine is Prevnar?
What type of vaccine is H influenzae type B?
What type of vaccine are the meningococcal vaccines?
What are the urease positive bugs?
CHuck Norris hates PUNKSS
What are the four pigment producing bacteria?
This bug produces yellow "sulfur" granules, which are composed of filaments of bacteria.
Actinomyces israelii (isreal has yellow sand)
This bug produces a yellow pigment
Staph aureus (aureus means gold)
This bug produces a blue-green pigment
Pseudomonas aeruginosa (Aerugula is green! haha)
This bug produces a red pigment
Serratia marcescens (red maraschino cherries!)1
This virulence factor binds the Fc region of Ig, thus preventing opsonization and phagocytosis
What bug expresses protein A?
This virulence factor is an enzyme that cleaves IgA and allows bugs to colonize the respiratory mucosa
What bugs carry IgA protease?
S pneumo, HiB, Neisseria
This virulence factor helps prevent phagocytosis.
