What are core principles of antimicrobial stewardship in veterinary medicine?

• A. Always use broad-spectrum antibiotics for any infection.
• B. Prescribe antibiotics for all conditions to prevent infections.
• C. Avoid educational outreach to clients about resistance.
• D. Culture and susceptibility to guide therapy; choose narrow-spectrum agents when possible; minimize duration and dosing errors; monitor resistance trends and educate clients.

Answer: (D)

Antimicrobial stewardship in veterinary medicine centers on using antibiotics only when needed, and in the most targeted, effective way. The strongest approach is to culture the infection and perform susceptibility testing to guide therapy, ensuring the chosen drug actually works against the organism. When possible, pick narrow-spectrum agents rather than broad-spectrum ones to spare normal flora and limit the broad collateral impact that drives resistance. Aim for the shortest duration that achieves cure and confirm dosing is accurate, so therapy is effective without excess exposure. Keeping an eye on local resistance patterns helps tailor choices over time, and educating clients about resistance, proper administration, and why a specific plan is chosen improves adherence and outcomes. This thoughtful, diagnostic-guided, and educational approach contrasts with using broad-spectrum antibiotics for every infection, prescribing antibiotics for all conditions, or skipping client education, all of which can worsen resistance and treatment success.
