Microbiology question

A patient is suffering from features of septic shock with following clinical picture.Most probable causative organism is
A) Staphylococcus
B) Listeria
D) Meningococcus

Answer is "D" that is Meningococcus.
It is a classical case of Waterhouse-friderichsen syndrome/Purpura fulminans/Fulminant meningococcemia:It is simply trauma to adrenal gland causing extensive bleeding, multiple organ failure, leucopenia, thromobocytopenia and consistent development of DIC.Low level of blood glucose and sodium and high level of ACTH and potassium level is suggestive of adrenal failure.
It differs from other septic shock because of the presence of prominent hemorrhagic skin lesions petechia, purpura.

  1. Your description isn't correct. The underlying cause isn't trauma to the adrenal glands. Bleeding into the adrenal glands is a result of severe meningococcal infection - trauma has nothing to do with it. Furthermore, you can have meningococcemia without Waterhouse-friderichsen syndrome.
