What is a potential consequence of long-term antibiotic use in ARD?

• A. Long-term microbiome disruption
• B. Rapid cure for all cases
• C. No side effects
• D. Increased vigor

Answer: (A)

Long-term antibiotic use in ARD can disrupt the gut microbiome. The gut hosts a diverse ecosystem that supports digestion, immune function, and barrier protection. Prolonged antibiotics reduce microbial diversity and can favor resistant or opportunistic bacteria, leading to dysbiosis. In antibiotic-responsive diarrhea, this means initial improvement might be followed by relapse or ongoing GI upset once antibiotics are stopped, and the overall microbial balance becomes harder to restore. This disruption also lowers colonization resistance and can predispose to secondary infections or inflammation. The other choices don’t fit because antibiotics don’t guarantee a rapid cure for all cases, they can have side effects, and increased vigor isn’t a typical outcome.
