The researchers have validated a reliable screening technique using mass spectrometry technology that identifies common biological markers - or biomarkers - between the interaction of host (humans) and the parasite. They found that in 99% of cases, the parasites left very specific markers. 'It's as if the parasite left his own signature in the infected person, which could help to diagnose Chagas disease" says Dr. Ndao.
"The use of these biomarkers is a revolution in diagnostic confidence and protection of possible contamination of blood banks," says Dr. Ndao "Moreover, these biomarkers have potential therapeutic effects of paving the way for the development of vaccines for Chagas, which could be extended to other parasitic diseases."
