title: [Common epitopes of protein antigens in Neisseria and Moraxella].
abstract: Cross reactions between N. meningitidis and M. catarrhalis proteins were studied with the use of a panel of monoclonal antibodies to M. catarrhalis protein antigens. All antigenic preparations under study were shown to give cross reactions between N. meningitidis serotype porin of 39 kD (strain B125) and M. catarrhalis proteins of 40-41 kD. These M. catarrhalis proteins belonged to main proteins of class F and had the function of porins in the cell. In addition, the epitope of 41-kD antigen, detected by monoclonal antibodies 3E10, is common for both N. meningitidis porin and N. meningitidis iron-regulated proteins of 70 and 50 kD. The epitope of M. catarrhalis protein of 67 kD, detected by monoclonal antibodies 1G6, is common for N. meningitidis porin and N. meningitidis iron-regulated proteins of 50 and 55 kD.
