  4. d Neck swelling, low grade fever, pseudomembranous pharyngitis
    Has a 3% mortality rate
  5. e MOA: Vancomycin binds to D-alanyl-D-alanine termini in cell wall peptide precursors and prevents the formation of peptidoglycan.
    MOResistance: Involves a change in the peptide precursor structure that alters the vancomycin binding site from a
    D-alanyl-D-alamine --> D-alanine-D-lactate
    -Substitution of D lactate in the place of D alanine during peptidoglycan cell wall synthesis

  3. Most common causes of osteomyelitis in childrenChylomicron particle shrinks:
    Chylomicron is synthesised by intestinal epithelial cells and are scaffolded on apoB-4 and are first drained into lymphatic tissue where they enter the thoracic duct, dump into blood and enter the bloodtsream where they are delivered to the capillary bed surrounding adipose tissue. Lipoprotein lipase breaks down the triglyceride being carried by the chylomicrons into glycerol and fatty acids. The glycerol is sent to the liver, while the fatty acids go to the adipose tissue.
    -The lipoprotein lipase is found on the capillary beds (endothelial tissue) around the adipose cells
