Model Card for ZOI Pro
Model Details
ZOI Pro is an application within the CarbConnect platform. This app streamlines antimicrobial susceptibility testing (AST) by automating the measurement of inhibition zones on agar plates. It analyzes images to determine areas where bacterial growth is inhibited and automatically provides SIR (Susceptible, Intermediate, Resistant) interpretations, delivering fast and reliable results.
Designed for microbiologists and researchers, the app enhances accuracy and efficiency in laboratory and research settings.
Intended Use and Limitations
This tool is strictly intended for Research Use Only (RUO) and is not for use in clinical diagnostics or medical procedures.

How to Use
A video tutorial demonstrating how to use the app is available on YouTube.
Difference from ZOI 1.0
Unlike ZOI 1.0, which relies on traditional image processing techniques, ZOI Pro employs deep learning models, making it significantly more robust to noisy images.
ZOI Pro also automatically outputs SIR (Susceptible, Intermediate, Resistant) interpretations based on CLSI's 34th Edition (2024), allowing for immediate confirmation of test outcomes.
Training Data
Antimicrobial susceptibility testing (AST) was conducted at CarbGeM Inc. using representative bacterial strains, antimicrobial disks, and Mueller-Hinton agar.
Approximately 300 images of the plates were captured using various smartphone camera models to generate the training dataset.
Evaluation Results
The model was evaluated using a test dataset comprising 66 images with a total of 237 antimicrobial disks.
| Metric | Result |
|---|---|
| Disk detection rate | 100% |
| SIR categorical agreement | 89.0% |
