Background and purpose: 

Splenic abscess is uncommon and is still associated with significant morbidity and mortality.
Gram-negative bacilli are the most commonly isolated organisms, followed by Gram-positive
cocci. However, the predominant organisms found depend on the geographic location. Shewanella
putrefaciens is a Gram-negative non-fermentative oxidative bacillus found in the environment.
Infection usually manifests with a number of clinical syndromes, most commonly
as skin or soft tissue infections, typically in patients whose immune system is compromised.
Intra-abdominal abscess is extremely rare. We report a case of a 22-year-old female who presented
with S. putrefaciens splenic abscesses as the first manifestation of diabetes mellitus,
which was successfully managed with a course of antibiotic therapy.
