Rod-shaped cells, conforming to the general definition of the family Enterobacteriaceae. Contain the enterobacterial common antigen. Gram negative. Motile, with peritrichous flagella. Facultatively anaerobic. Catalase positive (weak). Oxidase negative. Ferment, rather than oxidize, d-glucose and other carbohydrates. Reduce nitrate to nitrite.
The mol% G + C of the DNA is: 58–59.3 (Tm ).
