Advance provides genetic options for controlling spread of deadly disease Mosquitoes bred to be unable to infect people with the malaria parasite are an attractive approach to helping curb one of the world´s most pressing public health issues, according to UC Irvine scientists. Anthony James and colleagues from UCI and the Pasteur Institute in Paris have produced a model of the Anopheles stephensi mosquito – a major source of malaria in India and the Middle East – that...

Researchers at the Johns Hopkins Bloomberg School of Public Health have found evidence of a role for neighborhood immunity in determining risk of dengue infection. While it is established that immunity can be an important factor in the large-scale distribution of disease, this study demonstrates that local variation at spatial scales of just a few hundred meters can significantly alter the risk of infection, even in a highly mobile and dense urban population with significant immunity....

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...

Researchers have identified enzymes and biochemical compounds called lipids that are targeted and modified by the dengue virus during infection, suggesting a potential new approach to control the aggressive mosquito-borne pathogen. Their results appear March 22nd in the Open Access Journal PLoS Pathogens. Findings also suggest that medications used to treat high cholesterol and other lipid-related conditions might also inhibit dengue's replication and could represent a potential new...

Protein biomarkers allow early detection and could greatly reduce mortality Researchers at the University of Texas Medical Branch have developed the first accurate predictive model to differentiate between dengue fever (DF) and its more severe form, dengue hemorrhagic fever (DHF). The breakthrough, which could vastly reduce the disease's mortality rate, was reported in related papers in The American Journal of Tropical Medicine and Hygiene and Clinical and Translational Science. These...

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...

Flavivirus is a genus of the family Flaviviridae. This genus includes the West Nile Virus, Dengue Virus, Tick-borne Encephalitis virus, yellow fever virus, and quite a few others. Flaviviruses get their name from the yellow fever virus. Flavus means yellow in Latin. Yellow fever was named because if caused yellow jaundice in victims. Mosquitoes and ticks transmit these viruses by biting people. Human infections are usually incidental since humans are unable to replicate the virus. Yellow...

Aedes albopictus (Family Culicidae), the Asian Tiger Mosquito or Forest Day Mosquito, is characterized by its black and white striped legs and small, black and white body. It was native to south-east Asia, and occupied a habitat that spread from Madagascar eastward to New Guinea, and north to the latitude of Korea. The typical member of the Aedes albopictus has a length of about 5 mm. As with other members of the mosquito family, the female is outfitted with an elongated proboscis that she...
