Fulminant neonatal meningococcemia.
Neisseria meningitidis is a rare cause of infection in infants younger than 2 months of age, presumably because of transplacental passage of protective maternal antibodies. In most reported cases of meningococcal disease in neonates, a relatively mild clinical course has been observed. A 25-day-old infant survived acute, severe meningococcemia due to group B N meningitidis. This organism should  be considered when neonates have signs of septicemia, especially in the presence of cutaneous petechiae and purpura.
