Comparison of quantitative and qualitative antibody-producing cell responses to lipopolysaccharide in cell walls of the bacterial form and in membranes of the protoplast L-form of Proteus mirabilis

Abstract

Membranes of the stable protoplast L-form of Proteus mirabilis strain VI were highly immunogenic carriers of lipopolysaccharide when compared with the immune responses to lipopolysaccharide contained in cell walls of the bacterial form of this organism.
