Antimicrobial Drug Use in Humans and Animals: Considerations for Responsible Stewardship
Introduction
Antimicrobial drugs play a crucial role in human and animal health, safeguarding against bacterial infections. However, their widespread use has raised concerns about the development and spread of antimicrobial resistance, posing a significant threat to public health. Therefore, responsible antimicrobial stewardship is essential to ensure the continued effectiveness of these essential medications.
Applications in Veterinary Medicine
Antimicrobials are commonly used in veterinary medicine to treat a wide range of bacterial infections in animals. For instance, Campylobacter jejuni, a bacterium that can cause diarrhea in both humans and animals, is effectively treated with antimicrobials.
Drug of Choice for Campylobacter jejuni
Fluoroquinolones are the preferred drug for treating Campylobacter jejuni infections in both humans and animals due to their high efficacy and low resistance rates.
Classification of Antimicrobial Drugs
Antimicrobial drugs are classified into four categories (A-D) based on their potential risks to human health and their importance in treating human infections. Category A drugs have the highest priority and lowest risk for human health, while Category D drugs have the lowest priority and highest risk.
Examples of antimicrobial drug classifications include:
- Category A: Penicillins, cephalosporins
- Category B: Tetracyclines, macrolides
- Category C: Aminoglycosides, fluoroquinolones
- Category D: Sulfonamides, nitrofurans
Conclusion
Responsible antimicrobial stewardship requires careful consideration of the different applications of antimicrobials in both human and animal medicine. Proper classification of these drugs, along with responsible use and monitoring, is essential for preserving their effectiveness and safeguarding public health against the growing threat of antimicrobial resistance.
