Susceptibility testing predicts the likelihood of clinical efficacy
Longitudinal antimicrobial resistance pattern tracking helps optimize animal health outcomes across the industry

When identifying and tracking antibiotic susceptibility, a single clinical isolate is crucial in an outbreak, especially when treatment fails, presentation is atypical, or a local resistance problem is suspected. However, a larger antimicrobial surveillance program across different labs and different geographies provides several key advantages:

  • A stronger signal, allowing earlier detection of trends and shifts.
  • Broader representation across regions, production systems, and time.
  • Better context for interpretation. A large data set enables a deeper understanding of how commonly a bacteria or a pathogen is resistant to an antibiotic.

The Zoetis Susceptibility Surveillance Program is currently in its 29th year of data collection and comprises 12,000 isolates, enabling valuable insights into antibiotic susceptibility and resistance for optimizing animal health. Zoetis surveillance data is highly correlative with other large surveillance programs.

“The lower the rates of resistance, the better these antibiotic products will work, and we'll have a better clinical outcome and better animal welfare.”
