Point-of-Collection Silica-Coating and Preservation of Stool

Kenneth Stedman of Portland State University in the U.S. will test a low-cost and simple method for simultaneously collecting and stabilizing stool samples that can be used for diagnosing helminth infections in remote locations. The samples allow quantification of eggs from the helminth parasite, which causes intestinal infections that are endemic in many developing regions, and will help monitor large-scale treatment efforts. The method is based on his vaccine-stabilization technology, which was developed along with James Laidler at Portland State University.
