title: Surface K antigen in Salmonella paratyphi B.
abstract: It was established by agar immunoelectrophoresis that Salmonella paratyphi B lysate contains a large number of soluble antigens which display a varying degree of serological specifity as well as different diffusion and electrophoretic mobility. Salmonella paratyphi B was found to possess, apart from specific O and H antigens, a surface K antigen. This is a distinct antigen having strict serological specificity. Purified K antigen displayed anodic mobility in immunoelectrophoresis. A detailed study of K antigen properties in cultures treated by different methods as well as immunochemical investigations of purified K antigen showed that the surface K antigen of S. paratyphi B differs from its O, M, Vi, H and other known antigens in terms of basic characteristics.
