A parasite estimated to afflict as many as 12 million people worldwide relies on a family of genes that should make it vulnerable to compounds developed to treat cancer and other disorders, researchers at Washington University School of Medicine in St. Louis have found. Scientists searched the genome of the parasite Leishmania to determine that it has three kinds of TOR kinases, proteins that are linked to cell growth and cancer and have been longstanding targets for drug development. When...

Researchers propose new ways to combat prevalent public health challenge Chagas disease, for example, is caused by a parasite that roams with only limited control among the rural poor in Latin America. The main vector for the parasite Trypanosoma cruzi is the triatomine insect, or "kissing bug," which thrives in the nooks and crannies of mud-brick dwellings. The bug sucks the blood of mammals, helping T. cruzi move between wildlife, cats, dogs and humans. "Dogs tend to lie on porches or other...

A new bacterial species, found in the gut of the fly that transmits African sleeping sickness, could be engineered to kill the parasite that causes the disease. The study, published in the International Journal of Systematic and Evolutionary Microbiology, could lead to new approaches to control this fatal infection that is becoming resistant to drug therapy. Scientists from IRD, the French Research Institute for Development in Montpellier, France isolated the novel bacterium from the midgut...

Another test to detect Trypanosoma cruzi infection SILVER SPRING, Md., April 30 /PRNewswire-USNewswire/ -- The U.S. Food and Drug Administration today approved a second test to screen blood, tissue and organ donors for a blood-borne parasite, Trypanosoma cruzi (T. cruzi), that causes Chagas disease, a serious and potentially fatal parasitic infection. (Logo: http://www.newscom.com/cgi-bin/prnh/20090824/FDALOGO) The test, called Abbott Prism Chagas [Trypanosoma cruzi (E. coli,...

A team of researchers from McGill/MUHC validates a novel screening tool in the fight against Chagas disease Chagas disease is one of the most deadly parasitic diseases in the world. It affects more than 10 million people, primarily in the Americas. In South America alone it kills 50 000 people each year. A reliable and rapid diagnosis is the key in the battle against infection but until now, this has been next to impossible. Dr. Momar Ndao and his team at the Research Institute of the MUHC...

In the first survey of sand flies in Panama to use genetic barcoding, scientists at the Smithsonian Tropical Research Institute and Gorgas Memorial Laboratories identified 20 sand fly species from Barro Colorado Island. Two species carried Leishmania naiffi, a parasite that causes cutaneous leishmaniasis: persistent, itchy skin lesions. Three species carried Wolbachia, a bacterial parasite of insects that could contribute to a strategy to control the flies and limit disease transmission. "We...

A new simple, inexpensive three-in-one test to diagnose a terrible trio of parasitic diseases that wreak havoc in the developing world is passing preliminary tests, scientists reported Sunday March 21. Described during the 239th National Meeting of the American Chemical Society the test is for Chagas' disease, leishmaniasis, and "sleeping sickness" or African trypanosomiasis. This year will see about 800,000 new cases of Chagas disease, 2 million of leishmaniasis, and 70,000 of sleeping...

A single session of heat therapy using the ThermoMedâ“ž¢ device appears to be as effective as a 10-day intravenous course of sodium stibogluconate (Pentostam) for the treatment of Leishmania major skin lesions, according to a new study by Naomi Aronson and her colleagues at the Uniformed Services University of the Health Sciences and Walter Reed Army Medical Center (WRAMC). Results from the randomized treatment trial, which involved 56 military personnel who...

The northwards spread of human Rhodesian sleeping sickness in Uganda is likely due to the movement of infected livestock, according to new findings from an interdisciplinary research group including members from the Centre for Infectious Diseases, University of Edinburgh; the Ministry of Health, Uganda; and the Universities of Oxford and Southampton. The current study, published December 15 in the open-access journal PLoS Neglected Tropical Diseases, provides evidence that the spatial...

The parasite Trypanosoma cruzi (or T. cruzi), which causes Chagas' disease, will go to great lengths to evade death once it has infected human host cells, researchers have discovered. In a study published in the November 17 online issue of Science Signaling, the researchers describe how a protein called parasite-derived neurotrophic factor (PDNF) prolongs the life of the T. cruzi parasite by activating anti-apoptotic (or anti-cell-death) molecules in the host cell. These protective mechanisms...
