  • Title: [Detection of Neisseria meningitidis group B antigens by MB-Dot-Elisa test in patients with meningitis].
    Author: Alkmin MG, Landgraf IM, Shimizu SH.
    Journal: Rev Panam Salud Publica; 1997 Mar; 1(3):208-12. PubMed ID: 9162589.
    Abstract:
    Infection with Neisseria meningitidis group B has been difficult to detect, partly because this bacterial group's polysaccharide is a weak immunogen. This article describes work carried out to test a new procedure (MB-Dot-ELISA) employing a high-titered horse antiserum for detection of N. meningitidis group B antigens. The study assayed cerebrospinal fluid samples from 585 subjects, 574 with suspected meningitis cases and 11 with neurologic disorders. The results of the assay indicated a sensitivity of 0.991 and a specificity of 0.826. These results were superior to those obtained with latex agglutination and in substantial agreement with the results of counterimmunoelectrophoresis and bacteriologic methods. Overall, the MB-Dot-ELISA was found to be sensitive, inexpensive, and suitable for public health laboratory investigations.
