Salmonella anatum was first isolated in the United States by CitationRettger and Scoville (1920) from ducklings with an epidemic intestinal infection characterized by the birds “keeling” over before death. The condition is still known as “keel-disease”. S.anatum has since been isolated in the United States from the mesenteric lymph nodes of healthy pigs (CitationRubin et al., 1942) and from horses, cattle, sheep, goats, pigs, dogs, foxes, cats, rats, and a Gila monster (CitationBruner and Moran, 1949). In Mexico, its occurrence in man, pigs, cows, rats, and chicks was reported by CitationVarela and Olarte (1952), while in Sweden it was isolated from poultry and mink by CitationThal et al. (1957). In Britain, it was first identified in 1941 in cultures from imported spray-dried egg associated with food poisoning in man (Wilson and Miles, 1945), and subsequently isolated from dogs, cats, and pigeons (CitationCruickshank and Smith, 1949) and chicks and turkeys (CitationSmith and Buxton, 1951). In Australia, CitationStewart (1940) reported its occurrence in pips and horses, and CitationAtkinson et al. (1953) in sheep, ducks, pigs, chicks, cattle, and man.
