EXPORTED PROTEINS (PROTEIN WITH A SIGNAL SEQUENCE ESP ADHESION, VIRULENCE TOXIN AND IMMUNODOMINANT PROTEINS) FROM GRAM POSITIVE BACTERIA, DIAGNOSTIC TESTS THEREFOR AND MEDICAMENTS THEREOF

摘要

The present invention relates to the identification of Gram positive bacterial exported proteins, and the genes encoding such proteins. In particular, the invention relates to adhesion associated exported proteins, and to antigens common to many or all strains of a species of Gram positive bacterium. The invention also relates to acellular vaccines to provide protection from Gram positive bacterial infection using such genes or such proteins, and to antibodies against such proteins for use in diagnosis and passive immune therapy. In specific embodiments, fragments of ten genes encoding exported proteins of S. pneumoniae are disclosed, and the functional activity of some of these proteins in adherence is demonstrated.
