👉 Meningitides, also known as meningococci, are a group of bacteria that cause meningitis in humans. These bacteria can enter the bloodstream and travel through the body to other parts of the body where they can cause inflammation and infection. They are commonly found in the skin, respiratory tract, and central nervous system (CNS). Meningitides are also known as meningococcal meningitis or meningococcal encephalitis, depending on their severity.
