Antibiotic resistance in equine dermatology: what should we do?

This research discusses the issue of antibiotic resistance in horses with skin infections, specifically those infected with Staphylococcus aureus which can colonize and transfer to humans, potentially causing harm. The study emphasizes the need for veterinarians to practice responsible antibiotic use, along with prevention strategies, to combat this increasing threat to both animal and human health.

Antibiotic Resistance in Equine Dermatology

• This research paper primarily focuses on the problem of antibiotic resistance, particularly in horses experiencing skin infections. The most common bacteria in these situations is Staphylococcus aureus, which is not only harmful to horses but can also colonize in humans, causing potential health problems.
• Previous research has indicated that horses can become colonized with methicillin-resistant Staphylococcus aureus (MRSA), which can also be transmitted between horses and humans. Though MRSA colonization does not always lead to disease, it poses a risk to other horses, their owners, handlers, and especially veterinarians.

Implications for Human and Veterinary Health

• The World Health Organization has offered guidelines which determine the critical importance of different antibiotics for humans and identifies their levels of priority. This brings attention to the increasing pressure on the veterinary profession to minimize the use of antibiotics to limit the selection of resistant strains, which could negatively impact human health.
• Not many antibiotics are approved for use in horses, with few being third-generation cephalosporins. These fall under the category of critically important antibiotics. This research expresses concern over the high potential for transmission of resistant bacteria between horses and humans.

Recommendations for Appropriate Antibiotic Use and Stewardship in Veterinary Practice

• The study strongly advocates for changes in veterinarian approaches towards antibiotic use as well as the practice of responsible antibiotic stewardship.
• To combat antibiotic resistance, preventative measures should be taken to avoid infections in the first place by dealing with the root of the problem. In cases where skin infections are already present, appropriate topical antimicrobial therapy should be applied, while the use of systemic antibiotics should be minimized.
• Additionally, proper hygiene practices should be enforced, and horse owners should be educated about long-term management to prevent the spread of antibiotic-resistant infections.
