The family aeromonadaceae

Abstract

Aeromonadaceae, a family within the Aeromonadales, comprises the genera Aeromonas, Tolumonas, Oceanimonas, Oceanisphaera, and Zobellella. The family is distantly related to the families Enterobacteriaceae, Pasteurellaceae, Succinivibrionaceae, and Vibrionaceae. Members of the Aeromonadaceae share a number of major fatty acids and polar lipids that phenotypically define the family. They are strict aerobes or facultative anaerobes typically associated with aquatic environments. Strains of Aeromonas may also be recovered from foods, humans, and animals that have come into contact with water. Members of this genus may be opportunistic pathogens to humans and animals, in which they can cause a range of extraintestinal infections or diarrheal diseases. Information on the metabolism and ecology of Tolumonas, Oceanimonas, Oceanisphaera, and Zobellella is relatively scarce since most species of these genera were described on the basis of single strains.
