Neisseria meningitidis is a gram-negative diplococcus that is a leading cause of bacterial meningitis, particularly in college-aged adults and military recruits. It can cause meningococcemia and meningitis. Diagnosis is typically via lumbar puncture, showing increased white blood cells, decreased glucose, and increased protein. Treatment involves ceftriaxone, and close contacts may receive rifampin for prophylaxis. A vaccine is available for adolescents.
Elinea serogrupo B, C, Y, W serotipos capsulares causan la mayoría de las meningitis bacterianas, pero el serogrupo B es el más común en lactantes y niños pequeños, seguido por el serogrupo C en lactantes y niños pequeños. Los serogrupos Y y W también son comunes en la meningitis meningocócica, y pueden causar enfermedad epidémica, particularmente en el cinturón de meningitis de África. La enfermedad meningocócica se caracteriza por meningitis o meningococemia. La meningitis meningocócica se presenta con fiebre, dolor de cabeza, rigidez de nuca, náuseas y vómitos.
