title: [Etiological diagnosis of suppurative bacterial meningitis today].
abstract: As the result of laboratory examination of 2165 patients with virulent bacterial meningitides, including cases of meningococcal infection, the etiological diagnosis was confirmed in 1407 patients (65.0%), the number of cases confirmed by the laboratory examination being significantly greater among adults than among children: 67.5 +/- 1.37% and 63.1 +/- 1.53%, respectively, (t = 2.1). Meningococcal infection was confirmed in 1111 (70.6%) out of 1572 patients under examination. Of the patients with purulent meningitides, pneumococcal etiology was determined in 27.4%, type b of Haemophilus influenzae in 13.5%, other infective agents in 10.0%. The comparison of the results obtained in the examination, carried out by different methods, of 946 children and 770 adults with meningococcal infection revealed a considerable difference in the number of positive results yielded by the bacteriological method and countercurrent immunoelectrophoresis (CIE). Among adults meningococci were isolated twice as frequently (41.1 +/- 2.5% - 19.4 +/- 1.6%), and the results yielded by CIE were predominantly positive (55.1 +/- 2.5% and 40.1 +/- 2.5%). CIE and the immunoenzyme assay were shown to have advantages in the diagnosis of the disease. Under the conditions of intensive antibiotic therapy the methods based on the detection of specific antigens in body fluids can greatly assist in diagnosis.
