Antibiotics help fight against bacterial infections in both animals and humans. However, their overuse and misuse can lead to antimicrobial resistance (AMR), which the World Health Organization identifies as a significant global health threat.
In the veterinary field, responsible antibiotic use helps preserve the effectiveness of these drugs, ensuring they remain powerful against diseases and preventing the spread of resistant bacteria.
AMR occurs when microorganisms such as bacteria, viruses, fungi, and parasites change in response to the use of medicines, such as antibiotics, making infections harder to treat and increasing the risk of disease spread, severe illness, and death.
As future vets, you’ll need to understand the mechanisms of AMR and how your practices can influence its development.
The misuse of antibiotics in livestock and pets contributes to rising levels of resistance, which can have repercussions beyond animal health, affecting human medicine and global public health.
Addressing this issue is a critical part of your future role, where you’ll not just treat individual animals but also contribute to broader health policy and stewardship efforts.
For instance, certain bacteria, such as Escherichia coli, which can be harmless in the intestines of animals, can become highly problematic when they acquire resistance genes. These resistant bacteria can cause infections in humans, which are difficult to treat due to their resistance to conventional antibiotics.
In the veterinary setting, AMR is particularly concerning with pathogens like Salmonella and Campylobacter, commonly found in food animals and capable of transmitting to humans through the food supply.
The impact of AMR is profound. Globally, resistance in common bacteria has reached alarming levels in many parts of the world, suggesting that some infections may soon become untreatable.
Given the direct impact of veterinary practices on AMR, it is crucial for you to understand these dynamics and your role in mitigating this global health threat.
Antibiotic stewardship in veterinary medicine aims to improve the outcomes of antibiotic use while reducing its negative effects. These include toxicity, the spread of pathogens like Clostridioides difficile, and the development of antibiotic resistance.
The main goal is to ensure that treatments are effective and economically sensible, avoiding the extra costs linked to unnecessary use of antibiotics.
The key practices in antibiotic stewardship involve only using antibiotics when they are truly needed, which must be based on an accurate diagnosis.
It’s also crucial to select the appropriate antibiotic and dose to treat the infection and minimise the risk of bacteria developing resistance. Additionally, it is important to prescribe antibiotics for the right duration—long enough to cure the infection but not so long that it helps resistance to develop.
Education and policy support play essential roles in this area. Ongoing training for veterinary teams on the latest guidelines and information about resistance trends is crucial for informed decision-making about antibiotic use.
Moreover, robust policy frameworks need to support these practices across all sectors involved in animal care, ensuring that antibiotics are used wisely and sustainably. By doing so, we can maintain the effectiveness of antibiotics, safeguard animal health, and prevent drug resistance.
Implementing effective antibiotic stewardship in veterinary medicine comes with its set of hurdles, significantly complicated by diagnostic challenges. One major barrier is the scarcity of quick and readily available diagnostic tools, which are crucial for accurately identifying infections and deciding on the best treatment approaches.
Especially in rural or less financially equipped areas, the lack of these tools often forces veterinarians to rely on guesswork rather than specific, targeted treatments. This reliance on empirical treatments – broad-spectrum antibiotics chosen based on general experience rather than specific diagnostic results – compounds the problem of antibiotic resistance.
Economic and regulatory influences also pose significant challenges to antibiotic stewardship. The costs associated with setting up stewardship programmes and acquiring advanced diagnostic technology can be steep, particularly for veterinary practices working on tight budgets.
Furthermore, the regulations governing antibiotic use vary widely from one region to another, adding another layer of complexity. In some areas, lax regulation allows antibiotics to be sold over the counter without a prescription from a vet, which accelerates the pace at which bacteria develop resistance.
Ensuring that everyone follows stewardship guidelines is another uphill battle. Compliance requires a concerted effort from various parties, including veterinarians, animal owners, and farm managers, who must all buy into the need for change and often indiscriminate antibiotic use to more rational, justified practices.
Achieving this behavioural shift is no small feat and demands robust support through both education and regulation. Educating all stakeholders about the risks of antibiotic resistance and the benefits of stewardship, coupled with strong regulatory frameworks, is essential to foster adherence to best practices in antibiotic use.

Promoting responsible antibiotic use is crucial for maintaining the effectiveness of these treatments in both animal and human health. One key approach is through education. Ongoing training for veterinary professionals and educational programs for students are essential.
These programs should cover the latest research on AMR, effective stewardship strategies, and the consequences of improper use of antibiotics. Such education helps increase awareness about the importance of using antibiotics wisely and the potential impacts of misuse on public and animal health.
Surveillance and monitoring systems are also vital in managing antibiotic use and tracking resistance patterns. These systems gather data that helps us understand how antibiotics are used and how resistance is developing.
For example, in the European Union, the European Surveillance of Veterinary Antimicrobial Consumption (ESVAC) project collects data on antibiotic use in animals. This information helps shape policies and practices, ensuring they’re based on current data about antibiotic consumption and resistance trends.
Collaboration between various groups, including veterinarians, pharmacists, farmers, animal owners, and regulatory agencies, is essential to enforce responsible antibiotic use. This collaboration involves setting and following clear guidelines for antibiotic use, sharing best practices, and enforcing regulations to prevent misuse.
By working together, these stakeholders can ensure antibiotics are used judiciously, reducing the risk of antimicrobial resistance and ensuring these medicines remain effective for future generations.

Effective antibiotic stewardship in veterinary medicine is crucial for controlling antibiotic-resistant bacteria, ensuring animals stay healthy, and safeguarding public health and the environment. Misusing and overusing antibiotics can accelerate the development and spread of resistant infections.
Proper stewardship programs help slow down this process, making treatments more effective and reducing the strain on healthcare systems. This is essential as it not only helps in treating animals more effectively but also plays a part in maintaining public health standards.
Ensuring animals receive the right treatment at the right time also enhances their health and welfare. This approach minimises the need for repeated treatments, which can be costly and less effective if resistance develops.
For livestock, this means maintaining productivity without recurring expenses or losses from ineffective treatments.
Effective stewardship ensures that antibiotics are used wisely to avoid unnecessary treatments and prevent the development of resistance, which can be difficult and expensive to manage.
Moreover, responsible use of antibiotics in animals helps prevent the transfer of resistant bacteria to humans, which can occur through the food chain or environmental exposure. This is vital for public health as it helps prevent outbreaks of difficult-to-treat infections among the population.
It also protects the environment by preventing these resistant bacteria from contaminating ecosystems, which can have broader ecological impacts. Therefore, antibiotic stewardship is not just about keeping animals healthy, it’s about creating a safer environment and protecting public health.
Handling a situation where a client insists on antibiotics for an ailment that doesn’t warrant them requires a combination of empathy, education, and professionalism. The goal is to ensure the client understands the importance of appropriate antibiotic use while maintaining their trust and cooperation. Here is how you could approach this scenario:
Empathise and Acknowledge Concerns:
Begin by acknowledging the client’s concerns. They may be worried about their pet’s health and believe antibiotics are a quick fix. Express understanding of their perspective to build rapport. For instance, “I understand you’re very concerned about your pet’s health, and it’s important to address these issues promptly.”
Educate About Antibiotic Stewardship:
Use this opportunity to educate the client about antibiotic stewardship and the risks associated with unnecessary antibiotic use. Explain that antibiotics are only effective against bacterial infections and not viral or other non-bacterial ailments. Illustrate how misuse can lead to AMR, which can make future infections harder to treat. For example, “Using antibiotics when they aren’t needed can cause bacteria to become resistant, meaning that if your pet ever needs antibiotics in the future, they might not work as well.”
Provide Evidence-Based Recommendations:
Offer alternative treatments based on evidence and veterinary guidelines. Explain the diagnostic process and why antibiotics are not warranted in this case. For instance, “Based on the symptoms and our diagnostic tests, your pet’s condition is likely viral, and antibiotics won’t be effective. However, we can use supportive treatments such as fluids and rest to help your pet recover.”
Use Analogies and Examples:
Sometimes, using analogies can help clients understand complex concepts. For instance, “Think of antibiotics like a powerful tool. If we use it too often or inappropriately, it becomes less effective when we really need it, like using a sledgehammer for every small nail and then not having it when we need it for a big job.”
Offer Reassurance and Follow-Up:
Reassure the client that their pet’s health is the top priority and that you will monitor the situation closely. Schedule a follow-up appointment to check on the pet’s progress. For example, “Let’s see how your pet responds to the supportive care over the next few days. We can schedule a follow-up visit to ensure everything is progressing well.”
Maintain Professionalism and Authority:
It’s crucial to maintain a professional demeanour and uphold your clinical judgment. If the client remains insistent, gently but firmly reiterate the rationale behind your decision. “As a veterinarian, it’s my responsibility to prescribe treatments that are in the best interest of your pet’s health and to use antibiotics only when necessary. In this case, antibiotics are not the right choice.”
Document the Interaction:
Finally, document the interaction, including the client’s insistence and your educational efforts, in the pet’s medical record. This ensures there is a clear record of your clinical decision-making and the information provided to the client.
