Secrets to antibody's success against West Nile Virus surprise scientists
A monoclonal antibody that can effectively treat mice infected with West Nile virus has an intriguing secret: Contrary to scientists' expectations, it does not block the virus's ability to attach to host cells. view more (2005-09-29)
Genetically engineered mosquitoes show resistance to dengue fever virus
Researchers have successfully created a genetically engineered mosquito that shows a high level of resistance against the most prevalent type of dengue fever virus, providing a powerful weapon against a disease that infects 50 million people each year. view more (2006-03-09)
Genome circularization and RNA virus replication
As featured on the cover of the August 15th issue of G&D, an Argentinian research team, led by Dr. Andrea Gamarnik, report on their recent discovery of a novel mechanism of dengue virus replication. view more (2006-08-01)
Dengue Virus Reveals Its Circular Secret
The first step in the transmission of mosquito-borne viruses is no mystery: it's the pesky insect's bite that allows the virus to enter its victim's bloodstream. But for some of the most dangerous insect-borne viruses, details of what happens next have been unclear. view more (2006-08-02)
Biologists visualize protein interaction that may initiate viral infection
Biologists at Purdue University have taken a "snapshot" of a Velcro-like protein on a cell's surface just after it attached to the dengue virus, a linkup thought to initiate the early stages of infection. view more (2006-02-10)
Smaller mosquitoes are more likey to be infected with viruses causing human diseases
An entomologist at the Illinois Natural History Survey, a division of the new UI Institute for Natural Resource Sustainability, says smaller mosquitoes are more likely to be infected with viruses that cause diseases in humans. view more (2008-11-04)
Computer Models Aid Understanding of Antibody-Dependent Enhancement in Spread of Dengue Fever
Some viruses' ability to exploit the human body's own defenses to increase their replication may be both a blessing and curse, according to the findings of a study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. view more (2005-10-17)
How mosquitoes could teach us a trick in the fight against malaria
The means by which most deadly malaria parasites are detected and killed by the mosquitoes that carry them is revealed for the first time in research published today (5 March) in Science Express. The discovery could help researchers find a way to block transmission of the disease from mosquitoes to humans. view more (2009-03-06)
New lab mice pave way for novel studies of human infection
A new type of laboratory mouse developed at UT Southwestern Medical Center can fight certain infections the same way humans do, making the rodents very useful for novel studies of human-pathogen interaction and developing disease therapies. view more (2006-10-23)
Researchers put the bite on mosquitoes
Few things sting like a mosquito's bite--especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well. view more (2008-01-17)
Bioprospecting not biopiracy
By training professionals in high-biodiversity regions to advance the drug discovery process in-country, a novel program drives drug discovery costs down as it promotes tropical biodiversity conservation. view more (2006-12-08)
The cost of dengue fever challenges public health and national economies
A new study of the disease burden of dengue fever in Malaysia strengthens the case for development of a vaccine against the mosquito-borne illness. view more (2005-07-07)
UGA study explains peaks and troughs of dengue epidemics
Scientists have long known that epidemics of dengue fever wax and wane over a period of several years, but they've never been quite sure why. view more (2006-07-31)
Simple idea to dramatically improve dengue vaccinations
An innovative new study explains, for the first time, the failure of previous attempts to vaccinate against the four known Dengue viruses, and it suggests a very simple solution - injecting the four vaccines simultaneously at different locations on the body. view more (2006-03-30)
Dengue and other hemorrhagic fevers: Towards a first potential treatment
Globally, 60 to 100 million people are hit by Dengue, a viral disease transmitted by mosquitoes of the genus Aedes. The most severe form of this disease, which causes blood loss, can lead to a fatal shock-like state (Dengue Shock Syndrome) with or without associated haemorrhage, and is currently increasing in tropical countries. view more (2006-12-26)
Discovery may help defang viruses
Researchers may be able to tinker with a single amino acid of an enzyme that helps viruses multiply to render them harmless, according to molecular biologists who say the discovery could pave the way for a fast and cheap method of making vaccines. view more (2007-08-29)
Severe dengue infections may go unrecognized in international travelers
Severe cases of a common travelers' infection may not be recognized if doctors rely on the World Health Organization's (WHO) guidelines for identifying it. view more (2007-03-27)
Disease-free mosquito bred to disease-carrier can have all disease-free progeny
A decade ago, scientists announced the ability to introduce foreign genes into the mosquito genome. A year ago, scientists announced the successful use of an artificial gene that prevented a virus from replicating within mosquitoes. view more (2007-07-18)
First population study of GM mosquitoes highlights difficulties facing malaria control technique
The first laboratory population study of genetically modified mosquitoes identifies issues that need to be faced in the task of turning mosquitoes from disease carriers into disease fighters. Scientists from Imperial College London report in Science today that populations including genetically modified mosquitoes quickly lose their test marker... view more... (2003-02-18)
Ayurvedic nightshade deadly for dengue mosquito
Mosquitoes responsible for spreading disease are increasingly becoming resistant to synthetic insecticides. Now research published in the online open access journal BMC Complementary and Alternative Medicine suggests that the berries of a weed common to India, Solanum villosum (S villosum), have potential for keeping mosquitoes at bay. view more (2008-04-03)
