Follow on Google News | Discovery offers insight into treating viral stomach flu"Article of Significant Interest, sighting the extreme norovirus flexibility suggested by these results may allow for broad antibody recognition, a finding of potential vaccine significance.”
By: Melanie Bernds ST. LOUIS, MO, March 21, 2012—Twenty million Americans get sick from norovirus each year according to data released last week by the Centers for Disease Control (CDC). Often called vomiting illness, it can spread rapidly on cruise ships, and in dormitories and hospitals. Recent data from the CDC shows deaths from gastrointestinal infections have more than doubled and have become a particular threat to the elderly. The virus is shed in the stool of the infected individual, has a short incubation period and can spread quickly if proper hand washing and other measures are neglected. While researchers say that vaccines for intestinal infections are among the most difficult to develop, a recent discovery may provide the critical information needed for success. “Sometimes atomic structure gives us clues on how viruses work and how to make better vaccines,” said Dr. Thomas Smith, principal investigator, at The Donald Danforth Plant Science Center whose recent article, Structural Basis for Broad Detection of Genogroup II Noroviruses by a Monoclonal Antibody That Binds to a Site Occluded in the Viral Particle, in the Journal of Virology was selected by the editors as an, “Article of Significant Interest, sighting the extreme norovirus flexibility suggested by these results may allow for broad antibody recognition, a finding of potential vaccine significance.” Smith was part of a team of scientists lead by Dr. Peter D. Kwong, National Institute of Allergy and Infectious Diseases, National Institutes of Health (NIH). Their research demonstrated that the virus has a structure unlike that of other viruses in that is has protein “lollipop” Dr. Smith and his colleagues discovered that because of the “lollipop” This information will give researchers more insight on how to manipulate complex viruses as well as to design and develop better drugs to treat the maladies they cause. Rotovirus, a member of a different viral family but also causes severe gastro intestinal distress primarily in children, is being well controlled by the recent development of a vaccine.

Research at the Danforth Center will feed the hungry and improve human health, preserve and renew the environment, and enhance the St. Louis region and Missouri as a world center for plant science. The Center’s work is funded through competitive grants and contract revenue from many sources, including the National Institutes of Health, U.S. Department of Energy, National Science Foundation, U.S. Department of Agriculture, U.S. Agency for International Development, the Bill & Melinda Gates and Howard G.
