“…It is best known in Salmonella, described by Andrewes (1922) as a phenomenon wherein "Two well-defined types are present in every culture and apparently two only, but either may undergo transformation into the other". The variation for Salmonella is reversible; this type of variation also has been reported in the genus Arizona (Edwards and West, 1945;Fife et al, 1960). Edwards (1946) described another type of variation in Citrobacter in which the strain divided into distinct variants that did not share H antigens but between them contained all antigens of the parent strain and could not be reverted into their original parent form.…”

“…The phenomenon of phase variation, which affects flagellar antigens, and the presence of three flagellar phases in cultures of Entrobacteriaceae were reviewed briefly by Fife et al (1961). Attention was called to the fact that the presence of three readily reversible, naturally occurring antigens in a single bacterium had been observed only in three serotypes of the Arizona group.…”

SAKAZAKI, AND I. KATO. Natural occurrence of four reversible flagellar phases in cultures of Salmonella mikawashima. J. Bacteriol. 84:99-103. 1962-Study of cultures of Salmonella mikawashima isolated from reptiles revealed that single colonies of some strains contained three distinct H phases and that colonies of other cultures contained four such phases. In addition to the usual y and e,n,z,5 phases of S. mikawashima, two additional antigens which occurred naturally and which were identical with naturally occurring H antigens of the Arizona group, designated Z47 and z50, were recognized. Some cultures were represented by the formula 6,7 : y:e,n,z15:z47, some by 6,7:y: ,n,z15:z5o, and some by 6,7:y:e,n,z15:Z47:z50. The four H antigens were serologically unrelated, and each could be caused to revert to the others. Spontaneous reversions also were observed. The organisms underwent loss variation, and stable diphasic forms were encountered in which the e,n,z15 phase occurred in conjunction with y, Z47, or z50, indicating that the three antigens may be alternative forms of phase 1.
