          Abstract

          La infección por Neisseria meningitidis del grupo B ha sido difícil de detectar, en parte porque el polisacárido de este grupo de bacterias es un inmunógeno débil. En este artículo se describe el análisis de la validez de una nueva prueba, la MB-Dot-ELISA, en la cual se emplea un antisuero de caballo de alta titulación para detectar antígenos de N. meningitidis del grupo B. En el estudio se valoraron muestras de líquido cefalorraquídeo de 585 personas, 574 de las cuales padecían presuntamente meningitis y 11, trastornos neurológicos. La sensibilidad de la prueba fue 0,991 y la especificidad, 0,826. Estos valores fueron más altos que los de la aglutinación en látex y son muy compatibles con los de la contrainmunoelectroforesis y los métodos de análisis bacteriológico. La prueba MB-Dot-ELISA es sensible, barata y apropiada para realizar investigaciones en los laboratorios de salud pública.

          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.
