25
Definition of bioavailability?
amount of drug taken up into systemic circulation as a proportion of the amount administered
26
5 classes of antibodies?
IgG, IgM, IgA, IgE, IgD
27
3 examples of antigen presenting cells?
macrophages, dendritic cells, B cells
28
Describe how you would identify a bacteria as Salmonella using microbiology tests, incl. differentiating it from Shigella?
- Salmonella is a gram-negative bacilli, gram stain = pink - Bacilli appearance = rod shaped - MacConkey agar tests for fermentation, Salmonella does not therefore plate remains clear (fermenters go pink) - Do serotyping (API strip) to confirm Salmonella vs Shigella

HIV can be diagnosed by measuring the level of which specific WBC?
CD4+
30
Below what level of CD4+ count does it indicate HIV?
200
31

Basophil, neutrophil, eosinophil
32
Most abundant type of polymorphonuclear leukocyte
Neutrophil
33
Role of the MHC?
Present the processed antigen on the cell-surface
34
Stages of phagocytosis?
- Binding (e.g. bacterium to macrophage) - Engulfment - Phagosome formation - Lysosomal fusion and digestion - Antigen presentation (MHC II) - Secretion of waste products
