Abstract Chlamydia trachomatis releases a hydrophobic, group-reactive antigenic substance that can be isolated from culture media by a new method developed in this laboratory. Octyl-Sepharose binds the free, hydrophobic antigen but not the antigen complexed with specific antibody. Analysis by GLC, of derivatives of samples, demonstrated the presence of C17 and C18∶1 fatty acids and showed they were complexed with specific antibody. TLC analyses demonstrated a glycolipid band unique to preparations of isolated antigen. Neither analyses demonstrated similar material in uninfected media. It is suggested that the lipids may be complexed with a polysaccharide heteropolymer containing a form of the unusual hexose, gulose.
