Neisseria meningitidis and Neisseria gonorrhoeae

Neisseria meningitidis, also known as meningococcus is a Gram-negative bacterium which may cause meningitis or other forms of meningococcal infection like meningococcemia, which is life-threatening sepsis. The bacterium is described as a coccus due to the fact that it is round and, more specifically, is a diplococcus due to the tendency of it to create pairs.
