title: Soil-transmitted Helminths and Schistosoma mansoni Eggs Image Dataset

description: Context

This dataset was developed as part of the study “Deep learning-based automated detection and multiclass classification of soil-transmitted helminths and Schistosoma mansoni eggs in fecal smear images” (Oyibo et al., 2025, Scientific Reports).

The work aimed to build a deep learning-ready image dataset to support the automated detection and classification of Soil-transmitted Helminths and Schistosoma mansoni parasite eggs using low-cost digital microscopy. Images were captured using the Schistoscope, a cost-effective automated microscope, and supplemented with the AI4NTD KK2.0 P3.0 STH & SCHm (https://doi.org/10.34740/kaggle/ds/3675429).

The combined dataset addresses limitations of previous collections by improving class balance, incorporating diverse field samples, and supporting AI model development for diagnostic use in low-resource settings.

Data Summary



Source locations: Schistoscope dataset captured during field studies conducted in the Federal Capital Territory, Nigeria.

Sample type: Fecal smears prepared using the Kato-Katz technique (41.7 mg template).

Image acquisition: Schistoscope configured with a 4× objective lens (0.10 NA).

Total slides imaged: 300 stool samples (Schistoscope dataset) and 272 slides (AI4NTD dataset).

Resolution: 2028 × 1520 pixels - RGB - (Schistoscope dataset)  and  1640 x 1232 pixels - RGB - (AI4NTD dataset).

Total field-of-view (FOV) images in combined dataset : 10,562.

Egg classes included:



Ascaris lumbricoides - 8,600 eggs

Trichuris trichiura - 4,083 eggs

Hookworm - 4,512 eggs

Schistosoma mansoni -3,920 eggs



Annotations: Bounding box labels provided in COCO formats.

File formats: PNG for images and JSON for annotations.

Intended use: Training and evaluation of machine learning and deep learning models for automated parasite egg detection and classification.
