Which statement best differentiates colonization from infection in wound care?

• A. Colonization is the presence of microbes with tissue invasion
• B. Infection is merely presence on the surface
• C. Colonization and infection are identical
• D. Colonization is the presence of microbes without tissue invasion or damage

Answer: (D)

Colonization occurs when microbes are present on a wound but do not invade deeper tissues or cause tissue damage. Infection happens when those microbes penetrate tissues, multiply, and trigger an inflammatory response that harms tissue. So, describing colonization as the presence of microbes without tissue invasion or damage best differentiates the two. The other statements blur the lines by implying invasion is part of colonization, claiming infection is merely surface presence, or treating the two as identical.
