Origin and structure of the group-specific, complement-fixing antigen of Rickettsia rickettsii.

T Tzianabos, E L Palmer, J F Obijeski, M L Martin.

Abstract

Rickettsia rickettsii was treated with ether and examined by negative-contrast electron microscopy. Group-specific complement-fixing antigen was seen to be originating from the cell wall. The antigen was composed predominately of round particles 10 to 60 nm in diameter. Intact R. rickettsii and antigen from ether-treated organisms were purified by density gradient centrifugation and analyzed by polyacrylamide gel electrophoresis. The whole rickettsial cell was composed of a minimum of 30 proteins which ranged in molecular weight from about 23,000 to 155,000. The "soluble" antigen contained nine proteins ranging in molecular weight from about 28,000 to 150,000.
