Neis·se·ri·a me·nin·gi·'ti·dis

a bacterial species found in the nasopharynx of humans but not in other animals; the causative agent of meningococcal meningitis and meningicoccemia; virulent organisms are strongly gram negative and occur singly or in pairs; in the latter case the cocci are elongated and are arranged with long axes parallel and facing sides kidney shaped; groups characterized by serologically specific capsular polysaccharides are designated by capital letters (the main serogroups being A, B, C, and D).

Public health surveillance of meningococcal disease in Rio de Janeiro State is conducted by the Meningitis Advisory Committee of the State Department of Health, which uses data obtained from 2 surveillance sources: mandatory reports of meningococcal disease cases and reports of laboratory-confirmed N.
During the previous 3 months, the patient worked with only one known N.
During February 2011-June 2012, we observed an increase in invasive meningococcal disease caused by N.
Our findings indicate that travelers to the meningitis belt of sub-Saharan Africa may be at risk for infection with N.
This study provides a comprehensive description of all N.
The case definition for invasive meningococcal disease was isolation of N.
The PFGE pattern of this strain was compared with the PFGE patterns in the reference database of N.
Pulsed-field gel electrophoresis (PFGE), multilocus sequence typing, and outer membrane protein (porA) gene variant region subtyping were used to characterize the 4 case-related W135 N.
Subsequent testing using direct real-time polymerase chain reaction (PCR) confirmed N.
