Study on Neisseria Perflava from a Case of Cerebrospinal Meningitis  Dr. Lucas Assumpcão recently read a paper before the Society of Biology of São Paulo on the bacteriologic and immunologic study of Neisseria perflava which had been isolated from a case of cerebrospinal meningitis. He drew the following conclusions: In the bacteriologic examination of cerebrospinal fluid in which gram-negative diplococci, morphologically similar to meningococci, are found, it is necessary to isolate and identify the bacteria, because, owing to their form and staining properties, they may belong to any of the following species: Neisseria intracellularis (meningococcus), Neisseria gonorrhoeae (gonococcus) Neisseria catarrhalis (Micrococcus catarrhalis), and, the most probable, Neisseria perflava, N. flava and N. subflava. The author's experiments have proved that identification, by means of agglutination, is not possible. The safest process is by means of the fermentation of carbohydrates, in which the meningococcus can only be imitated by Neisseria subflava. It
