Veterinary Antimicrobial Susceptibility Testing Market Dynamics

Driver

“Rising AMR Awareness and Regulatory Push Toward Prudent Antimicrobial Use”

• The growing awareness of antimicrobial resistance (AMR) as a critical public health issue, combined with stronger regulatory pressures to reduce indiscriminate antibiotic use in animals, is a major driver of the veterinary AST market

  • For instance, in April 2024, the European Medicines Agency expanded its veterinary antimicrobial usage monitoring framework, encouraging the adoption of standardized AST to guide responsible treatment protocols in livestock. Such efforts are expected to accelerate the adoption of AST technologies during the forecast period

• As global veterinary professionals and animal health organizations seek more targeted antibiotic therapies, AST enables evidence-based treatment decisions that align with AMR mitigation strategies. This shift is especially prominent in high-output agricultural economies where antibiotic stewardship is tightly linked to food safety and export compliance
• Furthermore, increasing demand for pet healthcare and preventive diagnostics is pushing AST adoption in the companion animal segment. The rise of veterinary reference laboratories and portable point-of-care AST devices is enhancing test accessibility across clinical settings
• Technological advancements in rapid AST kits, cloud-based result sharing, and simplified workflows are making susceptibility testing more feasible for routine veterinary use, helping veterinarians tailor treatments and improve animal outcomes while preserving antimicrobial efficacy

Restraint/Challenge

“Limited Infrastructure and Cost Constraints in Developing Regions”

• The limited availability of veterinary diagnostic infrastructure in several developing regions poses a significant challenge to widespread adoption of antimicrobial susceptibility testing
• Many clinics lack access to specialized equipment, trained personnel, or standardized protocols required to implement AST effectively

  • For instance, in low-income countries, logistical issues such as sample transport delays, insufficient cold chain systems, and inconsistent laboratory capacities often hinder timely and reliable AST, restricting its use to urban or better-resourced areas

• In addition, the high initial investment and operational costs associated with automated AST systems and consumables can deter adoption, particularly among small-scale veterinary practices and livestock owners operating on tight budgets
• While lower-cost manual methods such as disk diffusion are more accessible, their longer turnaround times and dependence on technician skill can limit diagnostic accuracy and clinical utility
• Bridging this gap requires international support, public–private partnerships, and investment in affordable, field-deployable AST solutions tailored to low-resource settings
