N. meningitidis encodes 2,440 to 2,854 proteins while N. gonorrhoeae encodes from 2,603 to 2,871 proteins. N. weaveri (strain NCTC 13585) has the smallest known genome with only 2,060 encoded proteins although N. meningitidis MC58 has been reported to have only 2049 genes. The genomes are generally quite similar.

Neisseria Meningitidis is a bacteria that can cause meningitis in the brain.

BD Difco™ Neisseria Meningitidis Antisera are recommended for use in slide agglutination tests for serotyping Neisseria meningitidis.

Only Neisseria gonorrhoeae and Neisseria meningitidis are specific pathogens causing epidemic N. meningitidis are gram-negative, coffee-bean shaped diplococci that may occur intracellularly or extracellularly in PMN leukocytes.

Colony morphology of piliated Neisseria meningitidis. Blake MS(1), MacDonald CM, Klugman KP. Author information: (1)Laboratory of Bacteriology and Immunology, Rockefeller University, New York, New York 10021. An association between piliation and colony morphology has not been observed for the meningococcus. Pathogenic Neisseria meningitidis isolates contain a polysaccharide capsule that is the main virulence determinant for this bacterium. Thirteen capsular polysaccharides have been described, and nuclear magnetic resonance spectroscopy has enabled determination of the structure of capsular polysaccharides responsible for serogroup specificity.

Neisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae.Most gonococcal infections are asymptomatic and self-resolving, and epidemic strains of the meningococcus may be carried in >95% of a population where systemic disease occurs at <1% prevalence.

Neisseria meningitidis (the meningococcus) causes significant morbidity and mortality in children and young adults worldwide through epidemic or sporadic meningitis and/or septicemia. In this review, we describe the biology, microbiology, and epidemiology of this exclusive human pathogen. N.meningit … Pathogenic Neisseria meningitidis isolates contain a polysaccharide capsule that is the main virulence determinant for this bacterium. Thirteen capsular polysaccharides have been described, and nuclear magnetic resonance spectroscopy has enabled determination of the structure of capsular polysaccharides responsible for serogroup specificity. Abstract. Disease and carrier isolates of Neisseria meningitidis were examined for their ability to adhere to human buccal epithelial cells and human cell lines and to hemagglutinate human erythrocytes, properties thought to be associated with the presence of pili.
