  • H7N9 influenza is both lethal and transmissible in animal model for flu
    on October 19, 2017 at 6:30 pm

    In 2013, an influenza virus began circulating among poultry in China. It caused several waves of human infection and as of late July 2017, nearly 1,600 people had tested positive for avian H7N9. Nearly 40 percent of those infected had died. In 2017, a medical researcher received a sample of H7N9 virus isolated from a patient in China who had died of the flu. He and his research team subsequently began work to characterize and understand it. […]

  • Pair of discoveries illuminate new paths to flu and anthrax treatments

  • Usutu virus is back: Not only in blackbirds but also in humans
    on October 13, 2017 at 2:33 pm

    Usutu virus, a flavivirus of African origin, was first detected in Austria in 2001, when it caused a severe bird die-off, mainly of blackbirds. The virus was active in the eastern part of Austria until 2005, killing many blackbirds, but also other songbirds. During 10 subsequent years no Usutu virus associated bird mortality was observed in Austria -- contrary to neighboring Hungary. Last year Usutu virus was identified again in two blackbirds -- and in 2017 already in sixteen songbirds. In another study Usutu virus was demonstrated in seven human blood donations from eastern Austria, suggesting that human infections seem to be more frequent than previously thought.&nbs […]

  • Tracking the viral parasites of giant viruses over time
    on October 11, 2017 at 4:39 pm

    In freshwater lakes, microbes regulate the flow of carbon and determine if the bodies of water serve as carbon sinks or carbon sources. Viruses exist amidst all bacteria, usually in a 10-fold excess and include virophages which live in giant viruses and use their machinery to replicate and spread. Researchers have effectively doubled the number of known virophages. […]

  • How rabies can induce frenzied behavior
    on October 11, 2017 at 1:18 pm

    Scientists may finally understand how the rabies virus can drastically change its host's behavior to help spread the disease, which kills about 59,000 people annually. A new study shows how a small piece of the rabies virus can bind to and inhibit certain receptors in the brain that play a crucial role in regulating the behavior of mammals. This interferes with communication in the brain and induces frenzied behaviors that favor the transmission of the virus. […]

  • New approach for AIDS: Lock HIV in reservoir cells, to die through apoptosis
    on October 2, 2017 at 1:34 pm

    With the successful suppression of the AIDS virus (HIV) through medication, the focus turns toward its eradication. Researchers have developed a new compound that is key to the destruction of HIV. When the compound is introduced into infected cells, viral budding is suppressed thereby confining it within the host cells. The cell then dies naturally through apoptosis. This treatment is hoped to lead to the complete recovery from AIDS in the near future. […]

  • Biochemists discover mechanism that helps flu viruses evolve
    on September 26, 2017 at 3:20 pm

    Flu viruses' rapid evolution relies in part on hijacking some of the cellular machinery of the infected host cell -- a group of proteins called chaperones, which help other proteins fold into the correct shape. When viruses are unable to get help from these proteins, they do not evolve as rapidly, research shows. […]
