What is it about?
This article (https://www.nature.com/articles/s41429-026-00933-z) explains why resistance to sulfonamide antibiotics is no longer only a medical problem. Resistant bacteria and the genes that cause resistance are now found in people, farm animals, pets, wastewater, rivers, and soil. These resistance genes can move between bacteria, allowing resistance to spread across different environments. The paper focuses on the sul resistance genes (especially sul1, sul2, sul3, and the newly emerging sul4) and describes how they are becoming more common worldwide. It also explains that even when wastewater treatment removes antibiotic drugs, the resistance genes often remain in the environment and can continue spreading. The article highlights the One Health concept, showing that human health, animal health, and environmental health are closely connected. Because these systems influence one another, controlling antibiotic resistance requires cooperation across medicine, veterinary science, agriculture, and environmental management. The paper also discusses new technologies for monitoring resistance and possible strategies to reduce its spread in the future.

Why is it important?
This perspective brings together recent evidence showing that sulfonamide resistance is an environmental and global health challenge, not just a clinical problem. It highlights the growing importance of the newly emerging sul4 resistance gene and explains how resistance moves through interconnected human, animal, and environmental systems. By presenting the problem from a One Health perspective, the paper encourages researchers, healthcare professionals, veterinarians, and policymakers to work together instead of addressing resistance in separate sectors. It also identifies future directions for surveillance, wastewater management, and the development of new treatments, helping guide research and public health efforts against antimicrobial resistance.
Perspectives
Writing this perspective helped me realize that antibiotic resistance cannot be solved by focusing only on hospitals or human medicine. The scientific evidence shows that resistant bacteria and resistance genes continuously move between people, animals, and the environment, making this a shared global challenge. One aspect that particularly motivated me was the emergence of the sul4 resistance gene, which demonstrates how resistance continues to evolve and spread into new hosts and environments. I hope this work encourages researchers to adopt a stronger One Health approach and inspires further studies on environmental surveillance, resistance gene monitoring, and practical strategies to slow the spread of antimicrobial resistance. As a young researcher, I see this publication as an important step toward contributing to global efforts to protect the effectiveness of antibiotics for future generations.
