ZOI 1.0 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 plate images to identify antimicrobial disks and determine areas where bacterial growth is inhibited, delivering fast and reliable results for microbiology workflows.
Designed for microbiologists and researchers, the app enhances accuracy and efficiency in laboratory and research settings.
Intended Uses and Limitations
ZOI 1.0 is strictly intended for Research Use Only (RUO).
It is not intended for:
clinical diagnostics
medical procedures
patient management
therapeutic selection
any regulated medical use

How to Use
A video tutorial demonstrating how to use the app is available on YouTube.
Training Data
Antimicrobial susceptibility testing (AST) was conducted at CarbGeM Inc. using representative bacterial strains, antimicrobial disks, and Mueller-Hinton agar.
To generate the training dataset, approximately 300 images of agar plates were captured using various smartphone camera models.
Evaluation Results
We evaluated the model using a test dataset comprising 66 images with a total of 238 antimicrobial disks.
The model achieved:
98.3% disk detection rate
77.4% SIR (Susceptible, Intermediate, Resistant) categorical agreement
Task
ZOI 1.0 supports image-based AST analysis by detecting antimicrobial disks and measuring inhibition zones on agar plate images for research workflows.
