“…The MOMP, which is found in both EBs and RBs, is thought to act as a porin (Bavoil etal., 1984) and has a role in the attachment and uptake of EBs by host cells. It is also recognized as an exposed surface molecule possessing infection-neutralizing epitopes (Collett e t al., 1989 ;Zhang e t al., 1989 ;Conlan et al, 1989 ;Conlan et al, 1990;Peterson e t al., 1990). Polyacrylamide gel analysis of C. tracbomatis proteins has shown that the 60 kDa CrP occurs as a singlet in the trachoma biovar and as a 60/62 kDa doublet in the LGV biovar (Batteiger e t d., 1985).…”
