Researchers calculate surveillance and prevention of mosquito-borne disease known as 'break-bone' fever could save $5 for every $1 invested As public health experts warn that the spread of dengue fever could prove more costly globally and cause more sickness than even malaria, a new report published today in the May issue of the American Journal of Tropical Medicine and Hygiene finds each year dengue is inflicting a US$ 37.8 million burden on Puerto Rico and that every $1 invested in...

Changes promote blood-feeding behavior and virus transmission Mosquitoes infected with dengue virus experience an array of changes in the activity of genes and associated functions of their salivary glands, and these changes may lead to increased virus transmission, according to a recent study led by George Dimopoulos, Ph.D., of the Malaria Research Institute and Bloomberg School of Public Health at Johns Hopkins University. Some of these changes involve the mosquito's immune system and...

Researchers at the Johns Hopkins Bloomberg School of Public Health have, for the first time, shown that infection with dengue virus turns on mosquito genes that makes them hungrier and better feeders, and therefore possibly more likely to spread the disease to humans. Specifically, they found that dengue virus infection of the mosquito's salivary gland triggered a response that involved genes of the insect's immune system, feeding behavior and the mosquito's ability to sense odors. The...

As mosquito-borne viral diseases like West Nile fever, dengue fever, and chikungunya fever spread rapidly around the globe, scientists at Virginia Tech are working to understand the mosquito's immune system and how the viral pathogens that cause these diseases are able to overcome it to be transmitted to human and animal hosts. In nearly every part of the world, humans and animals experience high levels of morbidity and mortality after being bitten by mosquitoes infected with viruses. More...

Experiments by University of California Riverside entomologists demonstrate mosquitoes are attracted first to carbon dioxide, then to skin odors; findings could lead to more effective mosquito traps The carbon dioxide we exhale and the odors our skins emanate serve as crucial cues to female mosquitoes on the hunt for human hosts to bite and spread diseases such as malaria, dengue and yellow fever. Two entomologists at the University of California, Riverside have now performed...

Strains of a bacterium commonly found in fruit flies can prevent the Aedes aegypti mosquito from transmitting the virus that causes dengue fever, researchers have found. Their discovery could lead to a more effective way to control dengue worldwide. North Carolina State University mathematical biologist Dr. Alun Lloyd is part of the Eliminate Dengue program, a research consortium that includes scientists from Australia and the United States. The program aims to stop the Aedes aegypti...

Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a team of biochemists at the University of Arizona found Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered. The approach could be used as an additional strategy in the worldwide effort to curb...
