Infections originating from bacteria within the Neisseria genus are referred to as Neisseria infections. Neisseria Gonorrhoeae (gonococcus) is responsible for causing gonorrhoea, a prevalent sexually transmitted infection in humans. On the other hand, Neisseria Meningitidis (meningococcus) is the microorganism accountable for meningococcal meningitis, a condition characterized by inflammation of the membranes enveloping the brain and spinal cord.
