CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Kellogg (1, 2) was the first to recognize that Neisseria gonorrhoeae, when grown on solid agar, grew in distinctive colony types. He was able to show that gonococci growing in colonies, which he designated as types 1 and 2, were able to cause disease, whereas those he described as types 3 and 4 did not (1, 2).

Order: Neisseriales. Family: Neisseriaceae. gonorrhoeae and N. meningitidis). MATERIAL SAFETY DATA SHEET - INFECTIOUS SUBSTANCES. SECTION I - INFECTIOUS AGENT. NAME: Neisseria spp. ( Meningococcus, the bacterium Neisseria meningitidis, which causes meningococcal meningitis in humans, who are the only natural hosts in which it causes Neisseria meningitidis (meningococcus) and Neisseria · gonorrhoeae ( gonococcus), the well known agents of epidemic meningitis and gonorrhoea, respectively Neisseria meningitidis is a gram (positive/negative) organism, and as such stains pink on gram staining.
Our organism for the day likes it to the degree that makes it live in chocolate.. agar. Lucky Neisseria, isn't it? agent of gonorrhea, and N. meningitidis, an agent of acute bacterial meningitidis. Morphology and staining: a Gram-negative coccus, 0.6 to 1.0 µm in diameter, Neisseria meningitidis, the cause of epidemic meningitis and acute lethal sepsis, synthesizes surplus lipopolysaccharides (LPSs) during growth, which are gonorrhoeae and N. meningitidis are the only two species of the genus recognized as strict human pathogens, causing the sexually transmitted disease gonorrhea The genus Neisseria contains the important pathogens Neisseria meningitidis and Neisseria gonorrhoeae. These Gram-negative coccoid bacteria are generally Primary Culture and Presumptive Identification of Neisseria meningitidis, cytological examination of the CSF, specific colony morphology on blood and/or The most common causes of non-neonatal bacterial meningitis are Neisseria with a distinctive coffee-bean microscopic morphology associated with PMNs Aug 25, 2019 Although Neisseria meningitidis is one of the major causes of meningitis, It has a typical bean or kidney shape, and is an obligate human Figure 1.
Neisseria meningitidis is a gram-negative diplococcus bacterium that is responsible for endemic and epidemic meningococcal meningitis and fulminant meningococcemia Munford (2001). There are more than 500,000 reported cases of meningococcal disease per year, with an estimated annual death toll of 135,000 Zimmer and Stephens (2004).
Neisseria species may be misidentified as N. meningitidis in acid detection tests. Supplemental tests may be used to differentiate between them. Table 2. Differential characteristics of Neisseria spp.

CHARACTERISTICS: Neisseria meningitidis belongs to the family Neisseriaceae Footnote 2.
Actively growing colonies of N. meningitidis on a BAP are grey and unpigmented. Older cultures (> 24 hours) become more opaquely grey and sometimes cause the underlying agar to turn dark. 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.

Anomalous cellular morphology and growth characteristics of Neisseria meningitidis in subminimal inhibitory concentrations of penicillin G. Neirinck LG, DeVoe IW. The effects of subminimal inhibitory concentrations of penicillin G on Neisseria meningitidis in the presence and absence of selected stabilizers were examined.
