Soil taken from the Plantagenet King's remains was found to contain microscopic roundworm eggs.
The findings suggest that the higher concentration of eggs in the pelvic area probably arose from a roundworm infection the King suffered in his life, rather than from human waste dumped in the area at a later date, researchers said.
The roundworm Caenorhabditis elegans is studied because it has very defined development patterns involving fixed numbers of cells, and it can be rapidly assayed for abnormalities.
