Jan 01, 1969 · The biochemical and serological characteristics of lactose-utilizing strains of Neisseria were determined. These organisms were found in the nasopharynx of man and grew well on Thayer-Martin Selective Medium. They were compared with N. meningitidis to ascertain whether they were variants of this species. Differences between the lactose-using strains and the recognized species of Neisseria …

26 Sep 2018 Cause meningitis and other forms of meningococcal disease such as meningococcemia, a life-threatening sepsis. Categories Bacteriology,  During periods of endemic disease, about 10 % of the general population harbour Neisseria meningitidis in the nasopharynx. Since N. meningitidis is a strict human pathogen and most patients have not been in contact with other cases, asymptomatic carriers are presumably the major source of the pathogenic strains. Most carrier isolates are shown to lack capsule production.

Jun 17, 2015 · Introduction. Neisseria meningitidis (N. meningitidis) is an aerobic, Gram-negative diplococcus, exclusively hosted by man; it usually lives as a temporal commensal in the upper respiratory tract without causing any disease. Reasons for the transition from asymptomatic carriage to invasive disease have still not completely understood; anyway, some factors, such as genetic and capsular

UpToDate Part of the explanation for this phenomenon is the fact that meningitis due to Neisseria meningitidis tends to strike young, previously well individuals and can progress over a matter of hours to death. Mortality can be very high if the infection is not treated appropriately, and long-term sequelae can be severe even in successfully managed cases. Talk:Neisseria meningitidis - Wikipedia
