Bird Flu
Study findings on bird flu are outlined in reports from Pennsylvania State University
March 17th, 2009
"Revealing the factors that shape the genetic structure of avian influenza viruses (AIVs) in wild bird populations is essential to understanding their evolution. However, the relationship between epidemiological dynamics and patterns of genetic diversity in AIV is not well understood, especially at the continental scale," scientists in the United States report. "To address this question, we undertook a phylogeographic analysis of complete genome sequences of AIV sampled from wild birds in North America. In particular, we asked whether host species, geographic location or sampling time played the major role in shaping patterns of viral genetic diversity. Strikingly, our...
