[The detection of bacterial antigens by counter-immunoelectrophoresis in N. meningitidis, H. influenzae serotype b, S. pneumoniae infections. Diagnostic value and evolutive aspect (in 216 cases) (author's transl)].
Using counterimmunoelectrophoresis (CIE) the authors have assayed for soluble bacterial S. pneumoniae, N meningitidis group A, B, C. H. influenzae type b antigens, biological fluids in 216 patients (meningitis: 136; pneumonia: 76; miscellaneous: 4) during 16 months. Because of heterogeneous recruiting (the bacteriology was carried out by different laboratories) the increase in aetiological diagnosis given by CIE is only statistically valid for the bacteriologic negative group when blind antibiotic therapy had already been given. In this group, CIE makes a notable increase in diagnosis of 22,1 % +/- 10,1 in meningitis and 25,5% +/- 12,7 in pneumonia. Various physiopathological aspects are considered concerning soluble bacterial antigens detection during the course of the disease. This method seems very useful and accurate; and therefore should be used in every microbiologic laboratory.
