Monday we will cover chapter 14 (bacteria and archaea). Then on Wednesday we will have computer lab on bacteria. Check the /chapter14 site to find a word document describing the exercises, as well as web links. After that we move on to the eukaryotes.

(2005) performed phylogenetic analyses of 156 complete genomes of human H3N2 influenza A viruses collected over time (1999-2004) in one location (New York State). Phylogenetic analysis revealed multiple reassortment events. One clade of H3N2 virus, present since 2002, is the source for the HA gene in all subsequently sampled viruses. Large-scale influenza virus genome analysis Holmes EC, et al. Whole-genome analysis of human influenza A virus reveals multiple persistent lineages and reassortment among recent H3N2 viruses. PLoS Biol. 2005 Sep;3(9):e300. Page 576 Evolutionary Relationships of Concatenated Major Coding Regions of Influenza A Viruses Sampled in New York State during 1999–2004. The maximum likelihood phylogenetic tree is mid-point rooted for purposes of clarity, and all horizontal branch lengths are drawn to scale. Bootstrap values are shown for key nodes. Isolates assigned to clade A (light blue), clade B (yellow), and clade C (red) are indi
