Abstract
Three bacterial genomes that have recently been published identify common evolutionary strategies among extremely disparate organisms. All of these species inhabit specialized niches in association with eukaryotic organisms, and all of them show evidence of the long-term genome decay that accompanies the acquisition of the restricted lifestyle of a pathogen or endosymbiont.
