ACS Meeting News: Testing is fast and inexpensive by using arsenic immersion to identify parasitic diseases Elizabeth K. Wilson RAY TO TURN A dye containing (left), which glows when exposed to UV light, indicating the presence of a deadly parasite. A new radiation testing is being developed by researchers at SRI International, in Menlo Park, Calif.., Can detect very cheap and in just a few minutes on the existence of parasites that cause some deadly disease. Trypanosomatidae family of parasite causing Chagas disease in Central and South America, difficulty sleeping sickness in Africa, and leishmaniasis for millions of people around the world.
This parasite also causes a disease called nagana in cattle and horses. Recent testing requires expensive and blood analysis takes a long time or the antibody assays. SRI medicinal chemists are Ellen D. Beaulieu and Mary Tanga announced at a press conference at the ACS national meeting in San Francisco that they manipulate the family of arsenic and identify three dye that binds to the sulfur of the peptide group unique to the parasite trypanosomatid. Peptide complex dye glow in ultraviolet light then. In a period of five years, the team hopes to have the test "dipstick" cheap and easy to be transported on a poor and developing country. Beaulieu explained that the disease is second only to malaria in the case of the number of deaths from parasitic disease worldwide.
