APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Bacteria called Neisseria meningitidis cause meningococcal disease. About 1 in 10 people have these bacteria in the back of their nose and throat without being ill. This is called being ‘a carrier.’ Sometimes the bacteria invade the body and cause certain illnesses, which are known as meningococcal disease.

Detailed explanation-2: -Meningococcal meningitis evolves when the bacteria, Neisseria meningitidis (N. meningitidis) progresses from initial adherence to the nasopharyngeal (nose and throat) mucosa to invasion of the deeper mucosal layers (the submucosa). These bacteria rapidly multiply, and can lead to a mild (subclinical) infection.

Detailed explanation-3: -Several different bacteria can cause meningitis. Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis are the most frequent ones. N. meningitidis, causing meningococcal meningitis, is the one with the potential to produce large epidemics.

Detailed explanation-4: -Meningococcal disease refers to any illness caused by bacteria called Neisseria meningitidis. These illnesses are often severe, can be deadly, and include infections of the lining of the brain and spinal cord (meningitis) and bloodstream.
