Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them.
The influenza A viruses, which have instigated deadly pandemics in the past, still remain a major global public health problem until today. Molecules known as virulence factors are produced by bacteria, viruses, and fungi to help them to infect host cells.
Dangerous airborne viruses are rendered harmless on-the-fly when exposed to energetic, charged fragments of air molecules, University of Michigan researchers have shown.
Dubbed ‘Disease X’, scientists believe a future epidemic of the influenza virus could cause millions of deaths worldwide.
New research has taken a step towards understanding how highly pathogenic influenza viruses such as deadly bird flu infect humans.
A Phase 1 clinical trial examining whether a topical cream can enhance the immune response conferred by a "pre-pandemic" influenza vaccine is underway at Baylor College of Medicine in Houston.
Veterinary authorities in Bulgaria have called for culling of nearly 8,000 ducks according to a food safety agency yesterday after two more regions there have reported avian flu infection. According to the agency a total of four outbreaks of bird flu have been registered in Bulgaria at this time.
The official signboard-hanging ceremony of the Self-powered Mobile Tracker Research Center took place at UNIST on September 12, 2017.
University of Florida researchers will use a $2.7 million National Institutes of Health grant to study whether they can harness an unusual type of immune cell in pigs to treat and prevent influenza viruses in animals and humans.
InDevR, Inc., an innovative life science company dedicated to improving biopharmaceutical and vaccine manufacturing, announced support from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, for verification and validation studies on a new potency test for influenza viruses with pandemic potential.
Researchers at the University of São Paulo's Biomedical Science Institute (ICB-USP) in Brazil have discovered a new virus in a migratory bird species.
A systematic mutation analysis has shown that changes in just three amino acids of the avian influenza H7N9 virus receptor binding protein confers specificity for human cells.
Following the severe acute respiratory syndrome (SARS) outbreak in 2003, China stepped up its prevention and control methods for all infectious diseases, and rates of infection have levelled off since 2009.
The U.S. Department of Agriculture's National Institute of Food and Agriculture today announced $462,000 in available funding to decrease the impact of disasters through cooperative extension programming.
Researchers in Germany have developed a transgenic mouse that could help scientists identify new influenza virus strains with the potential to cause a global pandemic.
A resurgent outbreak of a new strain of avian influenza that can be lethal for humans underscores the need for robust and rapid detection and response systems at animal source.
New research from Vanderbilt eavesdrops on gene expression in human immune system cells before and after vaccination against bird flu.
Few influenza viruses are as widespread and adaptable as avian influenza viruses, and scientists are not entirely sure why.
Mass livestock production is driving molecular changes in diseases that could lead to human pandemics, according to an expert from the University of Exeter.
Zoonotic diseases are diseases or infections which are naturally transmissible from animals to humans, as defined in the OIE Terrestrial Animal Health Code.
Viruses can't live without us -- literally. As obligate parasites, viruses need a host cell to survive and grow. Scientists are exploiting this characteristic by developing therapeutics that close off pathways necessary for viral infection, essentially stopping pathogens in their tracks.
