What is it about?
This study evaluates the performance of deep learning models in predicting Nugent scores from Gram-stained vaginal smear images, a key method used to diagnose bacterial vaginosis (BV). We developed and tested several convolutional neural network (CNN) architectures to automate Nugent scoring, comparing their accuracy to human experts and ensemble models. The models demonstrated high predictive performance, suggesting the potential for reliable and standardized automated diagnostics in clinical microbiology.

Why is it important?
Nugent scoring is widely used to diagnose BV, but it requires expert interpretation of Gram-stained smears, which can be subjective and time-consuming. By using deep learning, we aim to standardize and streamline this process, reduce inter-observer variability, and improve diagnostic efficiency. Our findings support the integration of AI-based tools into routine diagnostics for vaginal infections.
Perspectives
As digital pathology and AI technologies continue to advance, automated interpretation of microscopic images could enhance diagnostic consistency in microbiology. This study lays the groundwork for implementing deep learning-assisted Nugent scoring systems, particularly in settings with limited access to trained microbiologists. Further validation across diverse populations and integration into clinical workflows will be key steps toward practical deployment.
