W F GOEBEL et al. J Exp Med. .

Abstract

By chemical fractionation a substance having colicine K activity has been obtained from the culture medium of E. coli K(235) L(+)O. Colicine K activity was found associated with the O antigen of this microorganism. When the O antigen was dissociated, colicine K activity remained with the protein component of the antigen.
