Scientists confirm new virus responsible for deaths of transplant recipients in Australia
In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, scientists from Columbia University Mailman School of Public Health, the Victorian Infectious Diseases Reference Laboratory (VIRDL) in Melbourne, Australia, the Centers for Disease Control and 454 Life Sciences link the discovery of... view more...

Scientists isolate world's oldest recorded plant virus
A Japanese poem written by Empress Koken, in the summer of 752AD, is thought to be the world's first record of a plant virus. Scientists from the John Innes Centre in Norwich (JIC)(1) have today reported, for the first time, the isolation and characterisation of the plant virus (eupatorium yellow vein virus - EpYVV(2) that causes the spectacular... view more...

New study may show how to forestall a fatal, virus-caused immune-system meltdown
When a virus infects a person, it triggers a series of biochemical reactions in immune-system cells that literally may have life or death consequences. view more (2007-02-15)
Molecular Anatomy of Influenza Virus Detailed
Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health in Bethesda, Md., and colleagues at the University of Virginia in Charlottesville have succeeded in imaging, in unprecedented detail, the virus that causes influenza. view more (2007-01-02)
Scientists discover new species of Ebola virus
Scientists report the discovery of a new species of Ebola virus, provisionally named Bundibugyo ebolavirus, November 21 in the open-access journal PLoS Pathogens. view more (2008-11-21)
Densovirus offers hope for biological control of Egypt's major cotton pest
Cotton plantations are highly important in Egypt, covering between 400 000 and 500 000 ha, 1/6 of all cultivated land. These crops are a vital source of foreign currency revenue through exports, and their state of health is therefore permanently under close surveillance. Cotton plants are indeed the target of a leaf-eating insect, the noctuid... view more... (2005-01-10)
FURTHER STEPS TOWARDS A VACCINE AGAINST HIV
For white blood cells in the human body to be infected by the HIV virus, proteins in the virus must be allowed to interact with a number of different components on the surface of the white blood cell. Ideally anti-HIV preventive therapy or vaccines would prevent several of these interactions taking place and would, therefore, reduce the likelihood... view more... (1999-03-11)
Hopkins study suggests commercially available antibiotic 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. view more (2006-04-06)
Studies in animals suggest 2009 H1N1 virus may have biological advantage over seasonal influenza
Preliminary findings in ferrets suggest that the novel 2009 H1N1 influenza virus may outcompete human seasonal influenza viruses, researchers say. view more (2009-09-01)
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)
Rates of genital herpes infections rise
Genital infections with Herpes simplex virus type 1 (HSV-1) have risen in western Scotland over the last 15 years, particularly among young women, finds a study in this week’s BMJ. view more (2002-06-05)
Icelandic volcano caused historic famine in Egypt, says Rutgers-based team
An environmental drama played out on the world stage in the late 18th century when a volcano killed 9,000 Icelanders and brought a famine to Egypt that reduced the population of the Nile valley by a sixth. view more (2006-11-22)
New host species for avian influenza identified
In a new study published online in the open-access journal PLoS Pathogens, Dr. Vincent J. Munster, of Erasmus Medical Center, Rotterdam, and colleagues identify new host species for avian influenza A virus (H5N1) and provide important information on the distinctions between the ecology and epidemiology of various global strains of the virus. view more (2007-05-11)
Bee disease a mystery
Scientists are one step closer to understanding the recent demise of billions of honey bees after making an important discovery about the transmission of a common bee virus. view more (2008-06-30)
Screening blood 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. view more (2006-01-24)
Specific Genotype Could Increase Resistance To HIV Drug Therapy (p 383)
A specific mutation of a gene which influences the expression of a glycoprotein transporter protein involved in the body's resistance to drugs and other toxins is detailed in a research letter in this week's issue of THE LANCET. Results of the study suggest that drug therapies used in treating HIV-1 infection (notably protease inhibitors ) may not... view more... (2001-08-01)
Substantial costs and underreporting of dengue fever, concerns about blood supply face US
Dengue fever, known as "breakbone fever" because of the excruciating back and joint pain that accompanies this infectious disease, is a growing public health threat for people living in tropical countries, as well as travelers to destinations such as Thailand, Brazil and Puerto Rico. view more (2007-10-17)
Jefferson Researchers Building a Better Rabies Vaccine
In an unexpected discovery, scientists at Jefferson Medical College have found that a tiny change in a rabies virus protein can turn a "safe" virus extremely deadly. The finding has enabled the researchers to refine a vaccine they previously created against rabies in wildlife, making it safer and more effective. view more (2006-01-06)
DNA of ancient lost barley could help modern crops cope with water stress
Researchers at the University of Warwick have recovered significant DNA information from a lost form of ancient barley that triumphed for over 3000 years seeing off: 5 changes in civilisation, water shortages and a much more popular form of barley that produces more grains. view more (2009-07-21)
LIAI completes world's most comprehensive analysis on influenza virus data
Researchers from the La Jolla Institute for Allergy & Immunology (LIAI) announced today the results of a first of its kind study analyzing all published data worldwide on influenza A virus antibody and T cell epitopes. view more (2007-01-02)
