This classification places the old genus Arizona (later Salmonella group 3a) as a subspecies. This microbe is a Gram negative rod-shaped bacterium that is associated with human gastrointestinal disease called salmonellosis, characterized by cramping and diarrhea. Its normal habitat is likely reptiles, particularly snakes. It has been associated with a variety of infections of turkeys and snakes, among other animal diseases. Sources are typically reptile in nature. The rods are straight and usually motile. Gas is produced when fermenting sugars, and hydrogen sulfide is frequently encountered. Growth occurs optimally at 35-37 C.
