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...

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...

Successful testing finally realizes decade-old theory Mosquitoes transmit infectious diseases to millions of people every year, including malaria for which there is no effective vaccine. New research published in Insect Molecular Biology reveals that mosquito genetic engineering may turn the transmitter into a natural 'flying vaccinator', providing a new strategy for biological control over the disease. The research, led by Associate Professor Shigeto Yoshida from the Jichi Medical University...

The first systematic study of surveillance techniques for the insect vector of Chagas disease in Amazonia, conducted by researchers from the Fiocruz Instituto Leônidas e Maria Deane, the Smithsonian Tropical Research Institute, the London School of Hygiene and Tropical Medicine and colleagues, concludes that tall palm trees with large amounts of debris on their crowns and stems should be targets for disease surveillance and control. Chagas disease, caused by a parasite...

Genetic approach could safely reduce or eliminate spread of disease affecting millions A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists. Dengue fever causes severe flulike symptoms and is among the world's most pressing public health issues. There are 50 million to 100 million cases per year, and nearly 40 percent of the global population is at risk. The dengue virus is spread through the bite...

New research shows how the migration and settlement patterns associated with the rapid urbanization of Peru may link to Chagas disease transmission. The study, published December 15 in the open-access journal PLoS Neglected Tropical Diseases, suggests that the practice of shantytown residents from Arequipa making frequent seasonal moves to rural valleys where Chagas vectors are present may have contributed to the growing presence of Chagas disease near urban Arequipa, Peru. Chagas disease...

Malaria parasites are able to disguise themselves to avoid the host's immune system, according to research funded by the Wellcome Trust and published Nov. 30 in the journal Proceedings of the National Academy of Sciences. Malaria is one of the world's biggest killers, responsible for over a million deaths every year, mainly in children and pregnant women in Africa and South-east Asia. It is caused by the malaria parasite, which is injected into the bloodstream from the salivary...

The Deer Fly (Chrysops spp.), also known as the "yellow fly", is a fly of the family Tabanidae that can be a pest to cattle, horses, and humans. It is often found in damp environments, such as wetlands or forests. It lays clusters of shiny black eggs on the leaves of small plants by water. The aquatic larvae feed on small insects and pupate in the mud at the edge of the water. The Deer Fly is often considered a horse-fly. A distinguishing characteristic is its patterned gold or green eyes....
