  • Mineral layer around avian flu pathogen may be the cause for human infections
    on August 18, 2017 at 2:25 pm

    Avian flu can be transmitted from birds to humans; transmission among humans, however, is limited. The reason may be an eggshell-like mineral layer that the virus acquires due to the high calcium concentration in the intestines of birds. These mineralized viruses are significantly more infectious and, in addition, more robust and heat stable than the native viruses. […]

  • Viruses up their game in arms race with immune system
    on August 14, 2017 at 7:15 pm

    Myxoma virus -- introduced to control the rabbit population in Australia in 1950 -- has developed a deadly ability to suppress the immune response in host rabbits. This example of an evolutionary arms race highlights the potential for escalating virus virulence and host resistance to produce more dangerous viruses with implications for agriculture and human vaccination, where resistance to viruses is artificially increased through selective breeding, genetic engineering, and immunization, potentially accelerating the arms race. […]

  • New tool to distinguish between viral, bacterial infections
    on July 28, 2017 at 7:39 pm

    Antibiotics are lifesaving drugs, but overuse is leading to antibiotic resistance, one of the world's most pressing health threats. Scientists identified 11 genetic markers in blood that accurately distinguished between viral and bacterial infections 80 to 90 percent of the time. The finding is important because physicians don't have a good way to confirm bacterial infections like pneumonia and more-often-than-not default to an antibiotic. […]
