Drought-induced amplification key to West Nile transmission

The spread of West Nile Virus appears to be triggered by a complex interaction of mosquitoes, nesting birds and specific weather patterns, scientists say, which leads to "amplification" of the virus within mosquito populations.

Ceftriaxone may help fight dementia in HIV patients

An antibiotic commonly used to treat a variety of serious infections may also help prevent dementia in HIV patients, according to a test-tube study of human brain cells by Johns Hopkins University School of Medicine neurologist Jeffrey Rumbaugh, M.D., Ph.D.

West Nile virus epidemics in North America are driven by shifts in mosquito feeding behavior

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.

Animals diseases jumping to humans faster than ever before

According to scientists in the U.S. and Scotland, 75% of the 38 species of harmful organisms and viruses identified in the past 25 years are believed to have "jumped" from animals to humans.

Purdue 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.

Discovery of the molecular mechanism that inhibits HCV replication in vitro

Since its discovery several decades ago, the insidious human pathogen has stymied the quest for anti-viral therapies by refusing to reproduce in test tubes for more than a few hours or days, denying scientists an efficient virus production and infection system for experimental research.

Health economics study questions recent policy on screening of US blood donations for West Nile Virus

A recent mandate to screen blood donations in all US states for West Nile virus (WNV) makes little sense from a public health point of view, say researchers from Columbia University and Harvard School of Public Health.

Genetic risk factor for West Nile virus infection identified

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, report researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

Mosquito threat to Europe from imported plants

Some experts believe that the importation of tropical plants into Europe may pose a disease risk to European countries because the plants harbour deadly mosquitos which carry the threat of exotic diseases.

New report identifies over 40 infectious agents that pose significant human health problems in the United States or abroad

Vaccines have helped eradicate and tame some of history's worst infectious diseases, but there are many more diseases out there that vaccines can help overcome. The challenges society needs to confront to unlock the future promise of vaccines against the plagues of the 21st century are the focus of a new report by the American Academy of Microbiology.

Flaviviruses immune system defenses in different ways depending on whether they are transmitted by mosquitoes or ticks

"Flaviviruses exact an enormous toll in terms of illness and death worldwide," notes NIAID Director Anthony S. Fauci, M.D. "Because this is a relatively new field of study, everything we learn about how these viruses operate is significant.

Dengue and other viruses may have developed tricks that let them reproduce inside macrophages

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. Instead, the antibody somehow stops the infectious process at a later point.
