In the February 2010 issue, p. 41, one of the authors of the letter entitled "Whole-Genome Sequencing (WGS) and the Changing Landscape of Bacterial Genetics" was inadvertently omitted. Shanmuga Sozhamannan of the Biological Defense Research Directorate Annex, Naval Medical Research Center, Rockville, Md., should have been included among the authors listed on p. 42. Microbe regrets the error.
