An unusual case of Septicaemia

We present a case of septicaemia with an initial diagnosis of meningococcal septicaemia, with purpura fulminans, disseminated intravascular coagulation and multi-organ failure. A blood film showed intracellular bacilli and a blood culture finally grew a Gram-negative anaerobic fusiform bacillus, which was subsequently identified as Capnocytophaga canimorsus.
