Abstract: | Abstract Strains of meningococci, which were shown to be pilated by electron microscopy, could be divided into two groups on the basis of antigenicity and subunit M r. Strains from group 1 which reacted with monoclonal antibodies directed against gonococcal pili, had pili with subunit M r similar to that of gonococci which could be detected by radioimmune precipitation or electroblotting. Strains from group 2 failed to react with the monoclonal antibodies and had pili with lower subunit M r which could only be detected by radioimmune precipitation using polyclonal antipilus antiserum and not by electroblotting. |
