Abstract

SUMMARY: Fimbriae (pili) were demonstrated in three of four Neisseria species () by electron microscopy. Only one of three strains examined exhibited these non-flagellar appendages. Haemagglutination occurred with all strains bearing such surface structures, but different species reacted in different ways. and agglutinated mouse and rabbit red cells at 0 and 37°; reacted similarly only with rabbit erythrocytes, and with human O cells at 0°. No reactions were observed with guinea pig, goat or sheep red cells. Prior heating of the organisms destroyed all obvious haemagglutination activity; addition of D-mannose did not inhibit haemagglutination.
