ZOI VET logo

ZOI VET is designed for use in veterinary microbiology and automates the Zone of Inhibition (ZOI) measurement process for antimicrobial susceptibility testing (AST). The app detects and measures inhibition zones from Petri dish images and determines susceptibility results—Sensitive, Intermediate, or Resistant (S/I/R)—based on the selected bacterial strain and antibiotic. The SIR result is used the criteria CLSI VET01S ED7:2024 – Performance Standards for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated From Animals published by the Clinical and Laboratory Standards Institute (CLSI). This tool helps laboratories reduce manual workload, improve standardization, and enhance result accuracy. ZOI VET is intended for Research Use Only (RUO).

CLSI

ZOI VET provides susceptibility classification based on the latest veterinary standards:

CLSI VET01S ED7:2024 – Performance Standards for Antimicrobial Disk and Dilution Susceptibility Tests for Bacteria Isolated From Animals,
published by the Clinical and Laboratory Standards Institute (CLSI).

The app is regularly updated to align with current veterinary AST guidelines, ensuring reliable and standardized results.

Target Users

  • Veterinarians: Quickly assess bacterial resistance in clinical cases.
  • Microbiologists: Perform standardized AST using digital zone measurement.
  • Researchers: Explore antimicrobial effectiveness in animal-specific pathogens.
  • Laboratories: Optimize workflow and ensure consistency in AST operations.

Key Features

  • Automated Zone Measurement: Instantly analyzes ZOI diameters from Petri dish images.
  • CLSI VET01S-Based S/I/R Classification: Automatically interprets results using current veterinary standards.
  • Image Upload & Annotation: Easily upload photos from PC or mobile, with optional manual adjustment.
  • Data Storage: Automatically saves results for tracking and retrospective analysis.
  • Remote Sharing: Share images and results securely for collaborative reviews.

Benefits

  • Efficiency: Saves time by automating ZOI measurement and AST interpretation.
  • Accuracy: Reduces measurement variability and improves reproducibility.
  • Veterinary-Focused Design: Purpose-built for veterinarians and animal health professionals.
  • Reliable Data Management: Automatically records results, aiding in data analysis and tracking.
  • Enhanced Collaboration: Allows real-time result sharing between team members or labs.

How It Works

  1. Upload an Image
    Take or upload a clear Petri dish photo via smartphone or PC.

  2. Run the App
    ZOI VET detects and measures inhibition zones automatically.

  3. Enter Details
    Input animal species, bacterial name, and antibiotic(s).

  4. Get Results
    The app classifies AST results (S/I/R) based on CLSI VET01S.

  5. Refine if Needed
    Manually adjust zone outlines if necessary.

  6. Save & Share
    Store or share results for further review and collaboration.

Caution When Photographing

  • Photograph from directly above.

Incorrect Petri Dish Photo Example Correct Petri Dish Photo Example

  • Ensure the entire dish is fully visible in the frame.

Photo with Light Reflection Example Photo without Light Reflection Example

  • Avoid reflections, glare, and shadows for best analysis quality.

Misaligned Plate Photo Example Properly Aligned Plate Photo Example

  • Align the edge of the plate with the shorter side of the image file (the shorter dimension of the image’s width or height).

Incorrect Plate Orientation Example Correct Plate Orientation Example
