What is microbiota-responsive diarrhea formerly called?

• A. Microbiota-responsive diarrhea
• B. Antibiotic-responsive diarrhea (ARD)
• C. Diet-responsive diarrhea
• D. Steroid-responsive diarrhea

Answer: (B)

The main idea is how the terminology evolved around diarrhea linked to the gut microbiota. Clinicians first observed that some dogs with chronic diarrhea improved after antibiotic therapy, so they called this pattern antibiotic-responsive diarrhea. That label highlighted the apparent role of bacteria and the antibiotics’ effect on them. As understanding of the microbiota grew, it became clearer that the important point is responsiveness to therapies that alter the gut microbiota, not the antibiotic action alone. So the modern term microbiota-responsive diarrhea describes the same phenomenon, and it’s remembered that it was formerly termed antibiotic-responsive diarrhea. The other options describe different treatment responses (diet, steroids) and don’t reflect the historical naming.
