The Genera Aeromonas and Plesiomonas

Traditionally the genera Aeromonas and Plesiomonas have been considered together. Three international workshops (International Workshop, 1986, 1988, 1990) have considered many different aspects of these two genera. In addition, the two genera are usually included in the same chapter or review (von Graevenitz, 1985). Only recently, however, has the relationship of the two genera been studied with methods that measure evolutionary distance. Although Aeromonas and Plesiomonas are not closely related, we have taken the traditional approach and considered them together in this chapter. However, we have separated most of our discussion because their differences seem more important than their similarities.
