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.
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.
Diverse antibodies induced in humans by vaccination with an avian influenza virus vaccine may offer broader, more durable protection against multiple strains of influenza than today's vaccines typically provide, according to a study led by Florian Krammer, PhD, Assistant Professor in the Department of Microbiology at the Icahn School of Medicine at Mount Sinai, and Patrick Wilson, PhD, Associate Professor in the Department of Medicine at the University of Chicago.
Researchers at Vanderbilt University Medical Center have isolated human antibodies against a type of bird flu that has killed more than 200 people in China since 2012 and which may pose a worldwide pandemic threat.
In response to the global call for urgently needed resources to fight the spread of the Zika virus, RB is announcing a Zika Relief Package of $1 million USD consisting of both cash and product donations that will be made available to health authorities and international NGOs battling the outbreak.
Scientists at Imperial College London have discovered how flu viruses 'hijack' cell machinery when they infect the body. The findings, published in the journal Nature, may pave the way for more effective antiviral treatments for pandemics and for seasonal flu, which infects over 800 million people worldwide every year.
The avian influenza A (H7N9) virus has been a major concern since the first outbreak in China in 2013. Due to its high rate of lethality and pandemic potential, H7N9 vaccine development has become a priority for public health officials. However, candidate vaccines have failed to elicit the strong immune responses necessary to protect from infection.
Vaccines to protect against an avian influenza pandemic as well as seasonal flu may be mass produced more quickly and efficiently using technology described today (Sept. 2) by researchers at the University of Wisconsin-Madison in the journal Nature Communications.
Scientists in the Center for Infection and Immunity at Columbia University's Mailman School of Public Health have discovered a new virus in seals that is the closest known relative of the human hepatitis A virus. The finding provides new clues on the emergence of hepatitis A.
Hoaglund Enterprises, Inc.,dba Asset Equipment Appraisals & Brokerage, a leading Nationally Certified Appraisal company is pleased to announce that they have been awarded a contract to appraise Avian Flu affected equipment that cannot be disinfected on infected farms by the USDA.
In a phase 2 trial that included nearly 1,000 adults, the AS03 and MF59 adjuvants (a component that improves immune response of inactivated influenza vaccines) increased the immune responses to two doses of an inactivated H7N9 influenza vaccine, with AS03-adjuvanted formulations inducing the highest amount of antibody response, according to a study in the July 21 issue of JAMA.
A vaccine that protects against a wide variety of influenza viruses (a so-called universal flu vaccine) is a critical public health goal given the significant rates of illness and death caused by seasonal influenza and the potentially devastating effects of a pandemic influenza strain.
