- 17What is the mnemonic device to help you remember examples of encapsulated bacteria?Please SHINE my SKiS
Pseudomonas aeruginosa, Strepococcus pneumoniae, Haemophilus, Influenzae type B, Neisseria meningitidis, Escherichia coli, Salmonella, Klebsiella pneumoniae, and group B Strep - 18What to the capsules of encapsulated bacteria serve as?Antiphagocytic virulence factor.
- 19Encapsulated Bacteria Capsular polysaccharide + what serves as an antigen in vaccines?Capsular polysaccharide + protein conjugate serves as an antigen in vaccines.
- 20Encapsulated bacteria are opsonized and then cleared by what?The spleen
- 21Why do Asplenics increase risk for severe infections? What should be given?Asplenics have low opsonizing ability and thus increase risk for sever infections. Give S pneumoniae, H influenzae, N meningitidis vaccines
- 22Some encapsulated bacteria vaccines containing polysaccaride capsule antigens are conjugated to a carrier protein, enhancing what? How is it enhanced?Enhancing immunogenicity by promoting T-cell activation and subsequent class switching.
- 23True or False A polysaccharide antigen alone cannot be presented to T cells.True
- 24What vaccines are encapsulated bacteria vaccines?Pneumococcal vaccine: PCV13 (pneumococcal conjugate vaccine), PPSV23 (pneumococcal polysaccharide vaccine with no conjugated protein)
H influenzae type B (conjugate vaccine)
Meningococcal vaccine (conjugate vaccine) - 25What are urease-positive organisms?Proteus, Cryptococcus, H pylori, Ureaplasma, Nocardia, Klebsiella, S epidermidis, S saprophyticus.

- 30What is the mnemonic device to help you remember catalase-positive organisms?Cats Need PLACESS to Belch their Hairballs
- 31Catalase degrades H202 into what?H2O and bubbles of O2
- 32Catalase degrades H2O2 into H2O and O2 before it can be converted to what?Before it can be converted to microbicidal products.
- 33Catalase degrades H2O2 into H2O and O2 before it can be converted to microbicidal products by what?By the enzyme myeloperoxidase.
