—Detecting Parasites “ACS Meeting News: Quick, inexpensive test uses arsenic-based dyes to identify parasitic diseases” A new fluorescence test being developed by researchers at SRI International, in Menlo Park, Calif., can detect inexpensively and within minutes the presence of a family of parasites that cause several deadly diseases. The Trypanosomatidae family of parasites causes Chagas disease in Central and South America, sleeping sickness in Africa, and leishmaniasis in millions of people worldwide. The parasite also causes a disease called nagana in cattle and horses. Current tests require expensive or time-consuming blood analyses or antibody assays.
