The epithet Salmonella has remained unchanged, but the species designations have undergone numerous changes, of which only the most recent changes are covered in this chapter. The initial method of naming salmonellae for clinical conditions and/or the animal host from which they were isolated (e.g., the name choleraesuis, from hog cholera) was abandoned, as it became apparent that many strains were not host specific or were not responsible for the disease for which they were named. The concept of three species, Salmonella choleraesuis, Salmonella enterica serovar Typhi, and Salmonella enteritidis, was proposed by Ewing in 1963, an idea originally put forth by Borman in 1944. Household pets capable of transmitting salmonellosis include cats, rabbits, ferrets, rodents (mice, rats, guinea pigs, hamsters, gerbils, and squirrels), turtles, lizards, snakes, and aquarium fish. Two major genetic elements have been identified in many important Salmonella serotypes that appear to play key roles in pathogenesis in both localized (enteritis) and extraintestinal (bacteremia) infections.
