← Nature & AnimalsWhich outcome results when antibiotics disrupt gut bacteriophages (viruses)?
A)Bacterial load increases with resistance✓
B)Commensal bacteria populations remain unchanged
C)Vitamin synthesis pathways always flourish
D)Phage diversity decreases gut stability
💡 Explanation
Disrupted gut bacteriophages increase bacteria because phage-mediated killing decreases, therefore bacterial load increases. This occurs because the lytic cycle stops, increasing bacterial survival, rather than maintaining populations regardless.
