PCTD plasmid isolated form chlamydia trachomatis serotype D, its genes and proteins encoded by them; recombinant plasmids for the expression of said genes in heterologous systems as fused recombinant proteins, preparation of said recombinant proteins and their use in the formulation of vaccins and/or gianostics.

摘要

A plasmid isolated from Clamydia trachomatis is described, which comprises 8 genes encoding proteins useful in the formulation of vaccines or diagnostic test for determining the bacterium or specific antibodies generated during C. trachomatis infections; in particular the recombinant fusion MS2-pgp3D protein is described comprising polypeptidic sequences encoded by pCT and immunogenic in the course of infections in man. A method for preparing said protein in E.coli further described.
