WASHINGTON: Swine flu - influenza A (H1N1) pandemic 2009 virus - that has killed over 1,500 people and left more than 27,000 people infected in India has acquired mutations that make it more dangerous than previously circulating strains of H1N1 influenza, a team of Indian-origin scientists from the Massachusetts Institute of Technology (MIT) has discovered.

<p>A research team of the Cluster of Excellence “Balance of the Microverse” at the University of Jena (Germany) is shedding light on the regulatory mechanisms of small RNA molecules—which play a decisive role in viral infections of bacteria</p>

The chikungunya virus, transmitted by Aedes aegypti and Aedes albopictus mosquitoes and responsible for more than 900 deaths in Brazil since it arrived around ten years ago, is capable of spreading through the blood, reaching multiple organs and crossing the blood-brain barrier, which protects the central nervous system.

University of Southampton scientists find bacteria form powerful defense alliances against phage viruses, aiding antimicrobial resistance fight.

Scientists at the University of Southampton have discovered that bacteria can pair up their defense systems to create a formidable force, greater than the sum of its parts, to fight off attack from phage viruses.

Understanding how bacteria react to this type of virus is a big step in combatting antimicrobial resistance.</p>

Bacteria in the gut influence how susceptible mice are to respiratory virus infections and the severity of these infections, research finds.

The study shows that the composition of gut microbiota determines the vulnerability to respiratory virus infections and their severity. | Health
