title: Capnocytophaga canimorsus sepsis presenting as an acute abdomen in an asplenic patient.
abstract: Acute abdominal symptoms are frequently caused by surgical intra-abdominal problems. However, the differential diagnosis also includes several internal diseases. Overwhelming infections may present with acute abdominal signs, particularly in the immunocompromised host. Asplenic patients are highly susceptible to infections with encapsulated bacteria such as Streptococcus pneumoniae, Haemophilus influenzae and Neisseria meningitidis. Severe infections due to Capnocytophaga canimorsus (DF2), are also common in this group. C. canimorsus is a Gram-negative rod, present as a commensal organism in cat and dog saliva. We describe the atypical presentation of a fatal C. canimorsus-sepsis in a 46-year-old man, who underwent traumatic splenectomy two decades earlier.
