Scientists warn against complacency on deadly H7N9 bird flu

(YourHealth) A new and deadly strain of bird flu that emerged in China in February but seems to have petered out in recent months could reappear later this year when the warm season comes to an end – and could spread internationally, scientists said on Monday. A study by researchers in China and Hong Kong  Read More »

H7N9 Flu: Worse than Pandemic, Better than H5N1

(MedPageToday) The novel H7N9 avian flu appears to be less severe than the highly pathogenic H5N1 avian flu but more severe than the 2009 pandemic H1N1 flu, researchers reported. The first estimate of the severity profile of the novel flu suggests that it kills 36% of those who are admitted to a hospital, according to  Read More »

Researchers strike gold with nanotech vaccine

(ScienceDaily) Scientists in the US have developed a novel vaccination method that uses tiny gold particles to mimic a virus and carry specific proteins to the body’s specialist immune cells. The technique differs from the traditional approach of using dead or inactive viruses as a vaccine and was demonstrated in the lab using a specific  Read More »

How cholera-causing bacteria respond to pressure

(EurekAlert) Cholera remains common in non-industrialized parts of the world today. It persists in part because V. cholera, the bacteria that causes the disease, is able to survive in diverse environments ranging from the intestinal lumen, to fresh water, to estuaries, to the sea. A study in The Journal of General Physiology provides new insights  Read More »

Researchers Identify Chemical Compounds that Halt Virus Replication

(GlobalBiodefense) Boston University School of Medicine (BUSM) researchers have identified a new chemical class of compounds that have the potential to block genetically diverse viruses from replicating. The findings, published this spring in Chemistry & Biology, could allow for the development of broad-spectrum antiviral medications to treat a number of viruses, including the highly pathogenic  Read More »
