H1N1 Pandemic Virus Does Not Mutate Into ‘Superbug’ In UMd. Lab Study
A laboratory study by University of Maryland researchers suggests that some of the worst fears about a virulent H1N1 pandemic flu season may not be realized this year, but does demonstrate the heightened communicability of the virus. Using ferrets exposed to three different viruses, the Maryland researchers found no evidence that the H1N1 pandemic variety, responsible for the so-called swine flu, combines in a lab setting with other flu strains to form a more virulent ’superbug.
Flu Virus Ill-Suited For Rapid Transmission, But Researchers Say New Strain Bears Watching, Could Mutate
A team from MIT and the Centers for Disease Control and Prevention has found a genetic explanation for why the new H1N1 “swine flu” virus has spread from person to person less effectively than other flu viruses. The H1N1 strain, which circled the globe this spring, has a form of surface protein that binds inefficiently to receptors found in the human respiratory tract, the team reports in the July 2 online edition of Science.
