Abstract

A study by light microscopy, using Leishman's stain alone or Leishman's stain followed by nigrosin, showed the presence of capsules on gonococci of two strains subcultured from subcutaneous chambers in guinea pigs. With the Alcian blue method of preparation for electron microscopy, gonococci of both strains recently grown showed densely stained capsules on some cells, while others in the same preparation showed only irregular masses of dense material on their surfaces with strands connecting adjacent bacteria. Treatment with antiserum, complement and conglutinin revealed irregular masses and strands of extracellular material with fixatives that did not contain Alcian blue.
