Flu chip could ID pandemic viruses
15th Nov 2006, 02:04 GMT
Scientists at the University of Colorado and the Centers for Disease Control and Prevention have developed a new inexpensive gene chip, which used in combination with a probabilistic neural network, can help quickly identify flu viruses, including the H5N1 strain of avian flu that could cause a pandemic in humans, the National Institute of Allergy and Infectious Diseases said. The institute funded the development of the new MChip. “Concerns about a possible influenza pandemic make it imperative that we continue to devise reliable and easy-to-use diagnostic tests for H5N1 that can be employed on-site where outbreaks are suspected," said Dr. Anthony Fauci, director of the institute. The new MChip performed extremely well in initial tests and has the potential to be a valuable tool in global influenza surveillance efforts, he added. The institute said the MChip research team, led by Kathy Rowlen, a professor at the university, used the MChip to detect H5N1 in samples collected from people and animals in large geographic areas including Vietnam, Nigeria, Indonesia and Kazakhstan...
