Abstract
EVIDENCE has been offered by one of us1 for the existence of properties correlated with sex compatibility in Escherichia coli. According to these data, sex-incompatible (F −) strains have a lower acid agglutination point and a far greater stability of broth-cultures as compared with F + strains of corresponding phenotype. These and other related properties of cell surface and the F + state are transmitted infectively from F + to F − strains at the same time. A search for an antigenic equivalent of such properties was but an obvious implication of these findings.
