Helminth Egg Automatic Detector

HEAD is an online service for the identification of helminth eggs from different environmental samples such as wastewater, soil, sludge and excreta.

About

Helminth eggs are among the most important biological pollutants in environmental engineering as they represent a significant health risk associated with poor sanitation, the use of polluted water for irrigation and the disposal to land of excreta or sludge.

Helminths are parasitic worms transmitted to humans via their eggs, which is the infective stage of their life cycle. They are relevant to the public health and environmental fields due to their very low infectious dose, their persistence in the environment (up to several years), and their high resistance to conventional disinfection processes. Visually identifying and counting the different types of helminth eggs needs a lot of practice in order to attain consistent and reliable results and, as such it, is the major source of error in the procedure.

HEAD Software

To overcome those difficulties, the solution developed is based on an integrated software to remotely identify and quantify helminth eggs from 11 species.

Ascaris lumbricoides -fertile and unfertile-, Trichuris trichiura, Toxocara canis, Taenia saginata, Hymenolepsis diminuta, Hymenolepis nana, Schistosoma mansoni, Ancylostoma duodenale, Necator Americanus, Fasciola hepatica, and Fasciolopsis buski.
