In the face of growing antimicrobial resistance and an increasing emphasis on stewardship, accurate antimicrobial susceptibility testing (AST) is essential in veterinary medicine. Minimum inhibitory concentration (MIC) values offer critical insights that support effective antibiotic selection, guide dose optimization using pharmacokinetic/pharmacodynamic (PK/PD) principles, and inform treatment in cases lacking defined clinical breakpoints. This whitepaper by Dr Libby Graham, European Specialist in Veterinary Microbiology, explores the value of accurate MIC determination as a key driver of responsible, evidence-based antimicrobial therapy in veterinary practice.

When it comes to veterinary susceptibility testing, look no further: Thermo Scientific Sensititre AST System offers species-specific plate formats and scalable automation options for every laboratory. Trust the definitive minimum inhibitory concentration (MIC) results to support optimized antimicrobial therapy for small and large animals, with a wide selection of antimicrobials including 40+ veterinary-specific drugs available on standard and custom formats.  

Available formats:

• Companion animal
• Bovine/porcine
• Bovine (mastitis)
• Avian
• Equine
• Urine samples
• Topical samples 

Effective antimicrobial resistance (AMR) surveillance is critical to identifying trends, sources, and the spread of resistance in bacteria. With growing concerns over antimicrobial use in food-producing animals and the risk of zoonotic transmission, harmonized monitoring and reporting are essential to protecting both animal and human health.

With surveillance programs outlined by international organizations such as the National Antimicrobial Resistance Monitoring System (NARMS) (humans CDC, retail meats FDA, food animals USDA) and the European Food Safety Authority (EFSA), resistance monitoring is a global effort in support against AMR.
