Veterinary Antimicrobial Susceptibility Testing Market Size

The global veterinary antimicrobial susceptibility testing market generated notable revenues in 2024 and is expected to grow at a decent CAGR during 2025 to 2034, driven by rising concerns over antimicrobial resistance (AMR) in both humans and animals, the growing demand for safe and effective veterinary treatments, and increasing awareness regarding animal health and the need for precise treatment approaches.
 

According to the World Health Organization (WHO), antimicrobial resistance in animals is a growing concern globally, with antibiotics in veterinary care often being overused or misused, contributing to the emergence of resistant strains. As antimicrobial resistance continues to be a significant global health threat, the veterinary sector’s need for accurate diagnostic tools, like antimicrobial susceptibility tests, becomes more crucial. These tests help identify the most effective antibiotics for treating infections in animals, improving both animal and human health by reducing the transmission of resistant pathogens.
 

As AMR poses serious risks to both human and animal health, governments, veterinary professionals, and researchers are working toward better solutions, including improved AST methods. Additionally, stricter regulations in several regions require veterinarians to conduct AST on infections to ensure the proper antibiotic treatment, driving demand for these diagnostic tools. However, the high cost of automated AST instruments and the lack of standardized testing practices across regions may limit the market growth.
 

Veterinary Antimicrobial Susceptibility Testing Market Trends

The veterinary antimicrobial susceptibility testing industry is witnessing a significant trend toward the automation of testing processes. The automation of antimicrobial susceptibility testing (AST) instruments is helping transform the veterinary diagnostic landscape. Automated systems provide faster, more accurate results than traditional methods, making them increasingly popular among veterinary professionals. Additionally, these systems help reduce human error and labor costs, improving the efficiency and reliability of testing, which is critical when managing large numbers of animals in commercial or clinical settings.
 

Furthermore, innovations in testing platforms and the growing popularity of point-of-care diagnostic tools are expected to revolutionize the market. The demand for faster and more efficient testing methods that deliver actionable results in real-time is increasing. This trend is particularly evident in the companion animal segment, where pet owners are more likely to seek immediate and reliable treatment for their pets.
 

Veterinary Antimicrobial Susceptibility Testing Market Analysis

Based on product type, the veterinary antimicrobial susceptibility testing industry is divided into automated AST instruments and manual AST kits. Automated AST instruments are expected to hold the largest market share during 2025-2034. These systems offer numerous advantages over manual methods, such as higher throughput, reduced turnaround time, and increased accuracy. Automated AST instruments can test large numbers of bacterial isolates from animal infections quickly and accurately, helping veterinary professionals choose the most appropriate antibiotics for treatment.
 

Automated antimicrobial susceptibility testing (AST) instruments are becoming increasingly essential in veterinary medicine due to their high efficiency, speed, and accuracy. These systems significantly reduce the time needed to perform tests, with results typically available in a few hours instead of several days. This is particularly critical for livestock farms or large animal care centers, where quick decision-making is vital to control outbreaks and ensure the timely administration of antibiotics.
 

Automated systems also provide more reliable and reproducible results compared to manual methods, reducing human errors that may occur during manual processes. These machines employ advanced technologies, such as microdilution and disk diffusion, to test bacterial isolates against various antimicrobial agents. These instruments help veterinarians determine the optimal treatment regimen, particularly for hard-to-treat infections or multi-drug-resistant pathogens.
 

In terms of animal type, the veterinary antimicrobial susceptibility testing market is segmented into livestock and companion animals. The livestock segment holds the largest market share through 2034 due to the widespread use of antibiotics in food-producing animals to prevent and treat infections. As the global demand for animal-based food products increases, the need for effective infection management in livestock is growing, leading to higher demand for antimicrobial susceptibility testing. Ensuring that animals receive the correct antibiotic treatment not only improves animal welfare but also prevents the development of antimicrobial-resistant pathogens that could impact both animal and human populations.
 

Livestock, including cattle, poultry, and swine, are at higher risk for infections due to the dense farming environments they are often kept in. As a result, the overuse and misuse of antibiotics in these animals are significant concerns, contributing to the rise of antimicrobial resistance.
 

In livestock farming, ensuring the appropriate use of antibiotics is crucial for maintaining animal health and preventing the spread of resistant bacteria. Veterinary AST helps in identifying the most effective treatment options for infections in livestock, which is crucial for both animal welfare and food safety. Furthermore, with increasing concerns over foodborne illnesses and the transfer of resistant bacteria from animals to humans, the need for accurate and reliable antimicrobial susceptibility testing is more important than ever.
 

North America veterinary antimicrobial susceptibility testing market is expected to hold the largest share of the market during 2025 to 2034. The region's dominance is attributed to several factors, including the high adoption rate of advanced veterinary technologies, a well-established healthcare infrastructure, and increasing awareness of the importance of antimicrobial resistance in both animals and humans. In the United States and Canada, regulatory agencies such as the U.S. Food and Drug Administration (FDA) and Health Canada are actively working to reduce the overuse of antibiotics in animals and promote responsible antibiotic stewardship. This includes the mandatory use of antimicrobial susceptibility testing in some instances to ensure the correct use of antibiotics. These regulations are expected to boost the demand for veterinary AST instruments in the region.
 

Furthermore, the increasing number of veterinary clinics and the rising awareness among pet owners in North America regarding the health risks associated with antimicrobial resistance are contributing to the growth of the market. The growing pet population and the increasing incidence of infectious diseases in companion animals further drive the demand for accurate and effective diagnostic tools.
