Abstract

Various ligands have been involved in the process of infection and tissue invasion of C. albicans 1. It is adherence is enhanced when germ-tubes are emerging from blastospores. The importance of yeast germination raises the possibility of a molecular organization of cell walls different between blastospores and hyphae. Major biochemical differences have been described,but the functional significance of the molecules specific to germ-tubes remains to be determined. Further features should be given by the hybridoma technology to identify surface antigens. Paradoxically a limited number of informative monoclonal antibodies was obtained by immunization of mice with whole organisms. Generally mannoproteins of yeasts cell wall were recognized 2,5. A different approach was attempted from fibrinogen binding factors released by the germ-tubes of C. albicans that we had reported previously 1. We describe the reactivity and characteristics of a murine monoclonal antibody 3D9 directed to a component of germ-tube of C. albicans.
