Shewanella dysentery in a patient with underlying malignancy

Shewanella spp is a facultatively anaerobic, motile, gramnegative bacillus and can be found throughout the world mainly in marine environments and soil. It is a rare pathogen in human and infection by it is usually associated with underlying severe morbidities. We report a case of a 69- years old woman who presented with Shewanella putrefaciens dysentery and who was subsequently found to have underlying malignancy.
