Connie K. Ho for redOrbit.com — Your Universe Online Scientists from the Helmholtz Association of German Research Centers and the Department of Energy´s (DOE) SLAC National Accelerator Laboratory recently revealed that X-rays could provide information on a novel biological structure that could possibly be developed into a sleeping sickness drug. The findings were discovered with the help of a free-electron laser that is considered the most powerful in the world. Sleeping...

Lies Van Nieuwenhove, researcher at the Antwerp Institute of Tropical Medicine, has produced proteins imitating typical parts of the sleeping sickness parasite. They can be used in more efficient diagnostic tests, without the need for culturing dangerous parasites. Each year many thousands of Africans contract sleeping sickness. The cause is a unicellular parasite, a trypanosome, which is transmitted by the bite of tsetse flies. First the parasite multiplies in blood and lymph, while...

Researchers have shown that the Trypanosoma cruzi agent of Chagas Disease (CD) invades host embryo cells and spreads its mitochondrial DNA (kDNA) minicircles into the host's genome. Dr. Antonio Teixeira and associates at the University of Brasília, Brazil, inoculated virulent typanosomes in fertile chicken eggs and documented the heritability and fixation of the kDNA mutations in the chicks and their progeny. The results, published in the open-access journal PLoS Neglected...

Research presented at American Society of Cell Biology's 50th annual meeting in Philadelphia Long considered a freewheeling loner, the Trypanosoma brucei parasite responsible for African sleeping sickness has revealed a totally unexpected social side, opening a potential chink in the behavioral armor of this and other supposedly solitary human parasites, according to research presented at the American Society for Cell Biology's 50th Annual Meeting in Philadelphia. "The concept of bacteria...

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,...

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...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
