← Human Body & HealthIf a catheter-associated biofilm infection exhibits increasing resistance to antibiotics, which consequence is most likely regarding horizontal gene transfer within the biofilm community?
A)Conjugation frequency decreases significantly
B)Transformation becomes the dominant mechanism
C)Antibiotic resistance genes spread rapidly✓
D)Transduction efficiency is severely limited
💡 Explanation
Biofilms facilitate horizontal gene transfer because they increase cell density and proximity, therefore antibiotic resistance genes can spread rapidly through conjugation, transduction, and transformation, rather than these processes being limited by distance or cell availability.
