THE<i>ARIZONA</i>group of organisms are gram-negative bacilli which resemble the<i>Salmonella</i>biochemically and serologically.<sup>1,2</sup>Biochemical differentiation from<i>Salmonella</i>is based on the ability of<i>Arizona</i>group to liquefy gelatin (delayed), ferment lactose (rapid or delayed), ferment malonate, and inability to ferment D-tartrate or dulcitol. Like<i>Salmonella, Arizona</i>possesses O and H antigens, which may be monophasic or diphasic. Edwards and Ewing have differentiated 33 O groups and 241 serotypes from cultures collected and isolated from numerous sources over a period of 20 years.<sup>3</sup> Although Edwards et al published an excellent review of the microbiological aspects of<i>Arizona</i>group in 1959,<sup>1</sup>it has not been generally appreciated that these organisms can produce serious, though fortunately uncommon, infections in man. The purpose of this paper is to present a patient with localized<i>Arizona</i>infection who recovered, and who was treated with antibiotics, based upon the results of tube-dilution
