Researchers dissect the influenza virus

MADISON, Wis., Jan. 26 (UPI) -- University of Wisconsin-Madison scientists say how the influenza virus organizes its genetic contents is selective and not random, as previously thought.

The researchers said their discovery might speed the development of antiviral drugs and vaccines, as well as the harnessing of benign influenza viruses as gene vectors to optimize vaccine protection.

"We've found that the influenza virus has a specific mechanism that permits it to package its genetic materials" as it creates its infectious particles, said Yoshihiro Kawaoka, a professor at both the University of Wisconsin's School of Veterinary Medicine and the University of Tokyo. He and a team of researchers from Japan, Sweden and California conducted the study using an electron microscope and a technique known as electron tomography.

Kawaoka said the findings might prove vital as the world's health officials deal with the possibility of an avian flu pandemic.

The research is detailed in the journal Nature.
