چکیده

A serum agar method for serogrouping Neisseria meningitidis is described and compared with conventional bacterial slide agglutination. There was 93% agreement for 300 strains examined individually by each method. Among strains from serogroups A, B, C, Y, and W135, there was 100% correlation, whereas strains from serogroup 29E (Z') had only 67% correlation. The serum agar method was rapid, as well as easy to perform and interpret. The potential benefits of this method for epidemiological studies and reference laboratories processing large numbers of meningococcal isolates are emphasized.

Use of real-time PCR to resolve slide agglutination discrepancies in serogroup identification of Neisseria meningitidis.

Neisseria meningitidis is a leading cause of bacterial meningitis and septicemia in children and young adults in the United States. Rapid and reliable identification of N. meningitidis serogroups is crucial for judicious and expedient response to cases of meningococcal disease, including decisions about vaccination campaigns. From 1997 to 2002, 1,298 N. meningitidis isolates, collected in the U...

In Silico Studies of Outer Membrane of Neisseria Meningitidis PorA: Its Expression and Immunogenic Properties

Neisseria meningitidis is a major causative agent of bacterial septicemia and meningitis in humans. Currently, there are no vaccines to prevent disease caused by strains of N.meningitidis serogroup B. The Class 1 Outer Membrane Protein (OMP) has been named porA which is a cation selective transmembrane protein of 45 KDa that forms trimeric pore in the meningococcal outer membrane. PorA from ser...

Identification and grouping of Neisseria meningitidis directly on agar plates by coagglutination with specific antibody-coated protein A-containing staphylococci.

It has been shown that Neisseria meningitidis can be grouped by coagglutination directly upon growth on sheep blood or chocolate agar plates. All positive reactions were group specific, and only a single colony was required for a positive reaction. There was variation seen in the effectiveness of commercial antisera in preparing sensitive reagents. Certain throat and sputum isolates of group Z ...
