Vaccine and drug research aimed at ticks and mosquitoes to prevent disease transmission
Most successful vaccines and drugs rely on protecting humans or animals by blocking certain bacteria from growing in their systems. But, a new theory actually hopes to take stopping infectious diseases such as West Nile virus and Malaria to the next level by disabling insects from transmitting these viruses. view more (2008-12-03)
New malaria vector species discovered in Africa
Malaria affects around 600 million people in the world and leads to an annual death toll of over 2 million. It is the world's most widespread parasitic disease. It is caused by Plasmodium falciparum, a pathogen transmitted to humans by a mosquito. In Africa, where malaria is endemic, mosquitoes of the Anopheles genus are the only vectors of the... view more... (2004-09-16)
Researchers develop the first climate-based model to predict Dengue fever outbreaks
Dengue Fever (DF) and Dengue Hemorrhagic Fever (DHF) are the most important vector-borne viral diseases in the World. view more (2009-06-08)
West Nile Virus Infection Greater Than Previously Thought (pp 254, 261)
A detailed analysis of the 1999 New York City outbreak of West Nile virus suggests that a substantial - and previously undiagnosed - outbreak of West Nile fever accompanied the 59 cases of West Nile meningoencephalitis, in which seven people died. The authors of the study, which is published in this week's issue of THE LANCET, conclude that for... view more... (2001-07-25)
The buzz on an amazing new mosquito repellent: Will it fly?
After searching for more than 50 years, scientists finally have discovered a number of new mosquito repellents that beat DEET, the gold standard for warding off those pesky, sometimes disease-carrying insects. view more (2009-08-17)
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)
Jeepers Creepers! Climate Change Threatens Endangered Honeycreepers
As climate change causes temperatures to increase in Hawaii's mountains, deadly non-native bird diseases will likely also creep up the mountains, invading most of the last disease-free refuges for honeycreepers - a group of endangered and remarkable birds. view more (2009-05-27)
Yellow fever threatens to make a come back
Yellow fever has been written off in the past as a global threat. Yet the failure to eradicate this disease has left the door open for new, large, outbreaks as vaccination of travellers and tropical populations declines, according to an article in the February issue of Microbiology Today magazine from the Society for General Microbiology. "Yellow... view more... (2002-02-11)
Entomologists exonerate mosquito in Kentish marshland killings
Medical entomologists believe that they have got to the bottom of the unusually high death rates recorded in the marshes around the River Thames, and the Essex and Kent coasts between 1700 and 1925. And for once the mosquito is not to blame. Speaking at the Royal Entomological Society’s national meeting Entomology 2002, which will take place... view more... (2002-09-04)
Global warming not responsible for malaria increase in East African Highlands
Recent increases in malaria in the East African Highlands cannot be attributed to global warming, researchers at the Department of Zoology at Oxford University have shown. It has long been known that malaria in highland areas is hindered by low temperatures which limit the development of the parasites in the mosquito. Recent upsurges of malaria in... view more...

Researchers investigate new suspect in West Nile deaths of pelicans
Stable flies are the latest suspect that may be involved in the West Nile virus deaths of hundreds of pelican chicks at the Medicine Lake National Wildlife Refuge in northeast Montana. view more (2007-10-01)
Mosquito genes explain response to climate change
University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate - and are apparently evolving - in animals in response to climate change. view more (2007-04-24)
Daily temperature shifts may alter malaria patterns
Daytime temperature fluctuations greatly alter the incubation period of malaria parasites in mosquitoes and alter transmission rates of the disease. view more (2009-08-04)
Researchers block the transmission of malaria in animal tests
By disrupting the potassium channel of the malaria parasite, a team of researchers has been able to prevent the malaria parasites from forming in mosquitoes and has thereby broken the cycle of infection during recent animal tests. view more (2008-06-10)
Malaria 2007 -- Progressing research, persisting challenges
In an editorial in this week's JAMA, Gianna Zuccotti, M.D., Contributing Editor, and Catherine D. DeAngelis, M.D., M.P.H., Editor in Chief, JAMA, comment on the status of malaria in the world today. view more (2007-05-23)
Shift in feeding behavior of mosquitoes sheds light on West Nile virus outbreaks
Since its introduction to the United States in 1999, West Nile virus has become the major vector-borne disease in the U.S., with 770 reported deaths, 20,000 reported illnesses, and perhaps around a million people infected. view more (2006-02-28)
Mutation that protects against HIV infection may raise risk of West Nile virus illness
People who lack a cell surface protein called CCR5 are highly resistant to infection by HIV but may be at increased risk of developing West Nile virus (WNV) illness when exposed to the mosquito-borne virus. view more (2006-01-17)
Drug industry, nonprofits join forces to fight world's neglected diseases
Drug companies and nonprofit organizations are joining forces to develop new drugs and vaccines to target so-called "neglected" diseases that claim millions of lives in the developing world each year. view more (2009-11-12)
Gene expression profiling of dengue virus infection in cell lines and patients
Researchers at the Novartis Institute for Tropical Diseases and the Genome Institute of Singapore have identified new host genes associated with dengue virus infection, which may open new avenues to developing a drug to treat the disease. view more (2007-11-07)
Troublesome North-American mosquitoes display resistance to insecticides
New evidence published online in Pest Management Science reports the first signs of resistance to pyrethroid insecticides in a population of mosquitoes from Marin County, California. The species in question is not only a major pest, but also acts as a vector of West Nile virus, a virus that spread rapidly westward across the United States after it... view more... (2004-01-09)
