Parasite Detection

Automatic diagnosis of worm infections in animals

Our system has been designed for automated egg detection from the ground up. 

This makes it consistent, with statistically robust results even in the presence of faecal debris. 

This creates opportunities far beyond the capabilities of manual faecal egg counting.

Egg Detection

State-of-the-Art Performance

Advanced detection rates


The WORMA Algorithm demonstrates excellent performance, with high sensitivity and specificity.

The Algorithm quickly delivers a breakdown of the number of each species of parasite present in an image. Confidence is well characterised so that error is implicitly taken into account.

Beyond human capabilities

New differentiation techniques can distinguish similar species

We have early evidence to suggest that the WORMA Algorithm can perform beyond human abilities. It has been shown that it can distinguish H. Contortus from other Strongyles, which is of great practical importance due to the different pathology of the two. Currently, this identification is only possible by staining or culturing eggs in the lab.

Hands-off Sample Preparation

A World-first method for nematode egg isolation

WORMA's sample processing is second to none. It’s task is to isolate parasite eggs from all of the detritus present in a faecal sample, and concentrate these so that they can be viewed in a single clean image.

This is the only system worldwide with this capability, and it achieves it without human intervention. This provides significant benefits in consistency and reduction in infection risk when handling samples.

Fully Automated Process

Load samples, and let the machine do the rest

Sample Collection

The WORMA device processes a large sample size, typically an order of magnitude larger than is traditionally used.


The WORMA device mixes the required fluids and processes the sample. It isolates parasites from faecal debris and concentrates these cells for imaging.


The WORMA device incorporates an intelligent optical instrument that delivers a high definition image to the WORMA Cloud for analysis.


The WORMA Algorithm works in the Cloud to autonomously speciate and count the parasites in each image. Results are available from any device.

Roundworm Modelling

Disease Prediction

Advanced models of parasite life-cycles used for forecasting

Advanced models of roundworm life-cycles, developed at the University of Bristol, are used to forecast spikes in parasite burden. Weather forecasts, Faecal Egg Counts from WORMA and historic climate data are used to estimate parasite behaviour. This provides an early-warning system for animal owners.
