Lethal Interactions

Researchers created this diagram to summarize their findings about lethal interactions among 185 strains of Vibriobacteria. Individual strains of bacteria are represented by the black lines protruding from the rim of the circle. Those adjacent to each other on the rim are more closely related than those farther apart. The black lines radiate from a Vibriofamily tree (displayed in circular form rather than the more common vertical). Figure courtesy of Otto Cordera, MIT.
