Abstract

Five bacterial strains labelled either Neisseria or Gemella haemolysans were studied with the electron microscope. They were found to be mutually alike and to possess a fine structure like that generally described for Gram-positive microorganisms. The mean moles per cent guanine + cytosine of the strains was 33.5 which is significantly different from the values hitherto obtained in the Gram-negative Neisseria.
