| What to the capsules of encapsulated bacteria serve as? | Antiphagocytic virulence factor. |
| Encapsulated Bacteria Capsular polysaccharide + what serves as an antigen in vaccines? | Capsular polysaccharide + protein conjugate serves as an antigen in vaccines. |
| Encapsulated bacteria are opsonized and then cleared by what? | The spleen |
| Why 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 |
