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...

A protein found in the saliva of ticks helps protect mice from developing Lyme disease, Yale researchers have discovered. The findings, published in the November 19 issue of Cell Host & Microbe, may spur development of a new vaccine against infection from Lyme disease, which is spread through tick bites. Traditionally, vaccines have directly targeted specific pathogens. This is the first time that antibodies against a protein in the saliva of a pathogen's transmitting agent (in this case,...

The Sterile Insect Technique (SIT), the release of sexually sterile male insects to wipe out a pest population, is one suggested solution to the problem of malaria in Africa. A new supplement, published in BioMed Central's open access Malaria Journal, reviews the history of the technique, and features details about aspects of its application in the elimination of malaria. The supplement, edited by Dr Mark Benedict, who along with the other editors led the development of this technology at the...

Top scientists reveal the latest innovations in genetically modified mosquitoes, new diagnostic tests and mapping mosquito migrations In a novel approach at disseminating scientific research, the Johns Hopkins Malaria Research Institute (JHMRI) will hold a web summit to release the latest breakthroughs in malaria research, including new approaches to boosting mosquito immunity to malaria, mapping mosquito migrations, and the promise of a rapid sputum test that could revolutionize the way...

WELLINGTON, Colo., Nov. 5 /PRNewswire/ -- The endangered black-footed ferrets inhabit prairie dog towns in the western U.S. This rare carnivore feeds on prairie dogs. The prairie dogs are very susceptible to plague and often entire population die-offs in towns occur. The U.S. Fish & Wildlife Service (FWS) has implemented a ferret breeding program and has been releasing trained, captive ferrets into their formerly native habitat. Unfortunately, plague can sweep through and decimate...

The parasites that cause leishmaniasis use a quirky trick to convince the immune system to effectively invite them into cells for dinner, according to a new study published today in PLoS Pathogens. The researchers, from Imperial College London, say their findings improve understanding of the way Leishmania parasites establish an infection and could aid the search for a vaccine against this neglected tropical disease.Leishmania parasites are transmitted by sand flies. After the parasites...

Vectors derived from retroviruses are useful tools for long-term gene transfer because they allow stable integration of transgenes and propagation into daughter cells. Lentiviral vectors are preferred because they can transduce non-proliferating cellular targets. These vectors can be engineered to target specific tissues. In the August issue of Cold Spring Harbor Protocols (www.cshprotocols.org/TOCs/toc8_09.dtl), François-Loïc Cosset and colleagues...

To control mosquito-borne diseases like dengue, researchers need to look at the behavior of people, not just the insect that transmits the disease, according to new research by Steven Stoddard of the University of California, Davis, and intercollegiate colleagues. The study, published July 21 in the open-access journal PLoS Neglected Tropical Diseases, exhibits work by an international, multidisciplinary team of vector biologists, sociologists and virologists studying dengue in Iquitos,...

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....
