ABSTRACT:
The present invention provides a novel protein of pathogenic forms of Neisseria, as well as genes which encode PilC, i.e., the pilC loci. DNA sequences of pilC genes are useful as probes to diagnose the presence of microorganisms containing type 4 pilin as well as permitting production of polypeptides which are in turn useful in diagnostic tests and/or as components of vaccines. The invention also provides antibodies directed against pilC epitopes. These antibodies are useful for diagnostic tests as well as therapy.
