In a dramatic breakthrough in the battle against malaria, researchers have identified a low-cost chemical that interferes with a mosquito's ability to detect humans, scientists said on Wednesday. Experts hope the findings could help develop the next generation of mosquito traps and repellents, which could confuse, deter or trap the insects. The chemicals consist of odor molecules that disrupt carbon-dioxide sensors that alert mosquitoes to exhaled human breath, which signals the presence of a...

ESA is helping to take the bite out of mosquitoes and their deadly diseases by tracking their distribution and habitat via observation satellites, satnav, and mobile communications. The Vecmap initiative is testing the accurate mapping of mosquitoes in Europe, in particular, mosquitoes carrying diseases, for public health agencies and regional mosquito controllers. Testing began in 2009 in the Netherlands, the UK, Belgium, France, Switzerland and Italy. Transmitters of disease such as...

Many gene therapy strategies designed to deliver a normal copy of a gene to cells carrying a disease-causing genetic mutation rely on a modified virus to transfer the gene product into affected tissues. One technology platform that is well suited for in vivo delivery of genes is based on adeno-associated viruses (AAV). As these novel therapies move closer to commercialization, so do the methods for large-scale production and efficient delivery of AAV vectors, which are documented in a series...

Overcoming the gene silencing barrier opens doors for gene therapy. Lincoln, NE (PRWEB) April 12, 2011 NTC today announced the award of a Small Business Innovation Research (SBIR) Phase II grant award from the National Institute of General Medical Sciences. The award represents a continuation of a Phase I study, which initially demonstrated the feasibility of overcoming transgene silencing, previously, a major barrier to successful gene therapy. In addition to anti-silencing elements, the...

SHAWNEE, Kan., April 11, 2011 /PRNewswire/ -- Leading experts from around the world came together today to share their latest research findings at the 6th Canine Vector Borne Disease (CVBD) forum in Nice, France and call for greater awareness of the dangers posed to animals and humans by these increasingly important diseases. "A number of the CVBDs cause real suffering and even death in dogs, and many CVBDs represent a zoonotic risk. It's vital that veterinarians and pet owners...

NIH-funded study finds way to reduce transmission of malaria to humans Spraying malaria-transmitting mosquitoes with a genetically modified fungus can kill the malaria parasite without harming the mosquito, potentially reducing malaria transmission to humans, according to a new study published in the journal Science. Funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, the study was led by Raymond J. St. Leger, Ph.D., of the...

There are over 200 million cases of malaria each year and, according to the World Health Organisation, in 2009 malaria was responsible for 781,000 deaths worldwide. Malaria is spread by mosquitoes which breed in open water and spend much of their larval stage feeding on fungi and microorganisms at the water surface. New research published in BioMed Central's open access journal Parasites and Vectors presents a method of dispersing pathogenic fungi as a means of preventing the spread of...

Scientists have discovered a new type of mosquito that is unlike any that have been documented before and could complicate the fight against malaria even further. Scientists from France collected mosquitoes from ponds near villages in Burkina Faso over a four-year period and said they identified some as a subtype of Anopheles gambiae -- which is responsible for most malaria transmissions in Africa. The new subtype is highly susceptible to infection with the malaria parasite and, because it...

British scientists have created genetically modified sterile mosquitoes in an experiment to kill off others in their species, and researchers are hopeful that early field trials could help to stave off the rapid spread of dengue fever. This is the first time genetically altered mosquitoes have been set loose in the wild, after years of lab experiments and calculations. But while scientists believe the trial could lead to a breakthrough in halting the disease, critics argue that mutant...

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....
