Notes This genus is a member of the bacterial family of "Enterobacteriaceae"- the so-called "Intestinal Bacteria" which includes Citrobacter, Edwardsiella, Escherichia, Enterobacter, Klebsiella, Salmonella, Shigella, Serratia, Proteus, and Yersinia amongst many others. Species included in this group are found worldwide; "in soil, water, fruits, vegetables, grains, flowering plants and trees, and in animals from insects to man." (B74) (B47) (B21) They are susceptible to sunlight, pasteurization, desiccation and common disinfectants They can survive for several months in damp, shady environments such as pastures, manure, bedding etc.. (B88)

Citrobacter spp. occur in the faeces of clinically normal animals and also in water, sewage, soil and food - their role seems to be as opportunistic pathogens. (B74)
