Douglas, G. W. (Communicable Disease Center, Atlanta, Ga.), Alma C. McWhorter, and P. R. Edwards. Natural occurrence of induced or artificial flagellar antigens in Salmonella newport. J. Bacteriol. 83:348-350. 1962.-Two epidemiologically related cultures of Salmonella newport, which possessed naturally occurring artificial or induced antigens in phase 2, were studied. It was demonstrated that similar antigens may be obtained by cultivation of normal S. newport cultures in appropriate antisera. These antigens were assigned the symbols 1,12. The diagnostic problems posed by the natural occurrence of induced antigens are mentioned.
