The Influenza Genome Sequencing Project, funded by the National Institute of Allergy and Infectious Diseases (NIAID), announces that the entire genetic blueprints of more than 2,000 human and avian influenza viruses taken from samples around the world have been completed and the sequence data made available in a public database.
This information will help scientists understand how influenza viruses evolve and spread, says NIH director Elias A. Zerhouni, MD, and it will aid in the development of new flu vaccines, therapies and diagnostics.
Scientists around the world can use the sequence data to compare different strains of the virus, identify the genetic factors that determine their virulence, and look for new therapeutic, vaccine and diagnostic targets, says NIAID director Anthony S. Fauci, MD.
The Influenza Genome Sequencing Project, initiated in 2004, has been carried out at the
Seasonal influenza is a major public health concern in the
An even greater concern is the potential for an influenza pandemic caused by the emergence of a new, highly lethal virus strain that is easily transmitted from person to person. Influenza pandemics have occurred three times in the last century, the most lethal of which was the pandemic of 1918, which caused an estimated 40 to 50 million deaths worldwide.
A few years ago, only limited genetic information on influenza viruses existed in the public domain, and much of the sequence data was incomplete, says Maria Y. Giovanni, PhD, who oversees the NIAID Microbial Sequencing Centers. The Influenza Genome Sequencing Project has filled that gap by vastly increasing the amount of influenza sequence data and rapidly making it available to the entire scientific community. Subsequently, there has been a marked increase in the number of scientists worldwide depositing influenza genome sequence data into the public domain including scientists at St. Jude Childrens
Along with NIAID, TIGR and NCBI, other collaborators on the project include the Wadsworth Center of the New York State Department of Health in Albany, NY; the Centers for Disease Control and Prevention in Atlanta; St. Jude Childrens Research Hospital in Memphis, TN; the World Organization for Animal Health / Food and Agriculture Organization of the United Nations (OIE/FAO) Reference Laboratory for Newcastle Disease and Avian Influenza in Padova, Italy; Ohio State University in Columbus, OH; Childrens Hospital Boston; Baylor College of Medicine in Houston; and Canterbury Health Laboratories in Christchurch, New Zealand.
