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).

influenzae type b 10 cases, streptococcus pneumoniae 15 cases and meningococcus only one case respectively.
It induces a higher and more sustainable immune response against group A meningococcus, it is expected to confer long-term protection not only for those who receive the vaccine, but to family members and others who would otherwise have been exposed to meningitis and it is expected to be particularly effective in protecting children under two years of age, who do not respond to conventional polysaccharide vaccines.
Teenagers, people from manual work social classes and those who have recently had colds are also at higher risk of carrying the meningococcus bug in their throats and noses, according to the research carried out at a Powys school.
VA-MENGOC-BC is the only vaccine available in the world against the disease caused by meningococcus B and has been included since 1991 in Cuba's national infant immunization program.
The higher percentage of vaccine coverage resulted in making the Sultanate free from several serious childhood diseases for a number of consecutive years, such as, polio, neonatal tetanus, meningococcus infection while the number of cases in other diseases fell to lower levels indicating that the Sultanate can eradicate diseases like measles as only three cases were reported and other three cases for German measles (rubella) while 38 cases were reported for whooping cough for 2009.
According to Professor Robert Booy, smokers are prime candidates for carrying the potentially deadly meningococcus bacteria in the back of their throats.
Encapsulated bacterial organisms such as Haemophilus influenzae serotypeb (Hib), Streptococcus pneumoniae (the pneumococcus), and Neisseria meningitidis (the meningococcus) are still the most common bacteria causing acute meningitis in infants and children worldwide, despite the availability of effective vaccines.
