Why does a burn victim with extensive skin damage have a high risk of opportunistic bacterial infection, particularly in areas lacking melanocytes?

A)Reduced nerve pain response
B)Decreased vitamin D synthesis
C)Impaired Langerhans cell migration
D)Compromised cutaneous immune defense

💡 Explanation

Burn victims often experience cutaneous immune compromise due to loss of skin barrier integrity, which disrupts the skin's physical and chemical defense mechanisms, because melanocytes contribute to immune signaling. Therefore, opportunistic infections are likely, rather than altered pain or vitamin D synthesis, as these are secondary effects.
