A COMPARATIVE STUDY OF THE DIPLOCOCCI OCCURRING IN EPIDEMIC CEREBRO-SPINAL MENINGITIS AND POSTERIOR BASIC MENINGITIS.

The study carried out and recorded in this paper did not lead to the finding of any reliable criteria of difference between strains of Diplococcus intracellularis obtained from typical cases of epidemic meningitis and several cultures obtained from cases of posterior basic meningitis. The successful experiments made with monkeys show that the diplococcus obtained from cases of posterior basic meningitis is capable of setting up rapidly and acutely fatal forms of meningitis and in producing organic lesions of the cerebral tissues of great severity. This study would, therefore, suggest that the antimeningitis serum should be as useful in cases of posterior basic meningitis so-called, as it has been in epidemic meningitis, especially if it were employed early in the disease.
