Study reveals key avian flu protein needed to create pandemic strain
A research group, including investigators from the US Centers for Disease Control and Prevention, used human 1918–avian H1N1 reassortant influenza viruses to explore the genetic factors that influence airborne transmission. Using ferrets as a model, they found that the 1918 PB2 protein was needed for airborne transmission of a virus expressing the 1918 hemagglutinin and neuraminidase, an adaptation that is critical for an avian flu strain to develop into a pandemic strain. Their findings appear in an early online edition of Proceedings of the National Academy of Sciences (PNAS).

Army biolab officials say older samples skewed inventory reports
More details emerged yesterday about select agent inventory problems that stopped some research work at the US Army Medical Research Institute of Infectious Diseases (USAMRIID) in Frederick, Md., the Baltimore Sun reported. Officials discovered 20 vials of a select agent in a freezer box listed as containing only 16 vials. Army officials attribute the inventory problems to older research samples that were stored before the institute computerized its records in 2005, and they said a full inventory could take 3 months.
