Summary: Transient (T) forms of resemble both virulent smooth (S) and avirulent rough (R) forms. We studied the effect of the T1 antigen on mouse virulence by introducing the gene, which determines the synthesis of T1-specific structures, into S and R forms. The T1 antigen slightly increased the very low virulence of the R forms. When present together with the O antigen in T1, S hybrid forms the T1 antigen had the opposite effect: it reduced by virulence of the S form considerably. This effect was probably due to the concomitant reduction in the amount of O antigen.
