Illustration of Meningitis bacteria (Neisseria meningitidis). N. meningitidis are gram-negative diplococci (spherical bacteria arranged in pairs), transmitted by the respiratory route. In most people they cause either asymptomatic infections or non-severe nasopharyngitis, but can also cause severe meningitis and generalised infection (meningococcaemia), particularly in children. | |
