1. The gonococcus and meningococcus, for example, are coffee-bean shaped.

2. Group A meningococcus accounts for an estimated 80-85% of all cases in the meningitis belt, with epidemics occurring at intervals of 7-14 years.

3. Meningococcus B is the most common cause of meningitis in Britain.

4. His team is working on a vaccine for meningococcus B, the bacteria that cause meningitis.

5. Meningococcus strain A causes explosive epidemics every eight to ten years, mainly in the African 'meningitis belt' that stretches from Senegal and the Gambia in the west to Ethiopia in the east.

6. The level of contagion is low, but occasionally meningococcus can occur in outbreaks and become a serious cause of morbidity and mortality.

7. For example, in the UK babies are vaccinated against group C Meningococcus as part of their routine immunisation programme.

8. The epidemic meninges epidemic sentiment processing plan epidemic meninges inflammation (i. e. epidemic cerebrospinal meningitis), is the suppurative meningitis which the meningococcus cause.

9. Conclusion The developed synthetic medium and purification procedure were feasible and provided an experimental basis for the preparation of tetravalent meningococcus polysaccharide vaccine.
