Former name for Salmonella enterica, subspecies arizonae.
The name ‘Arizona’ appears to have been applied in one form or another to a group of Salmonella-like organisms since the late 1930's according to the 7th edition of Bergey's Manual (1957) where it was called Paracolobactrum arizonae. Serological similarity with Salmonella was usually a noted feature along with the atypical (for Salmonella) tendencies to ferment lactose and liquefy gelatin. Later names included Arizona arizonae, Arizona hinshawii and Salmonella arizonae before being completely absorbed into the modern Salmonella scheme as two of the recognized subspecies.
