Shewanella algae - A Novel Organism Causing Bacteremia: A Rare Case and Literature Review

Shewanella species are distributed ubiquitously in the soil and water, being common in the marine habitat. Although these bacilli were thought to be rarely pathogenic, there has been an increasing number of reports of them being implicated in a wide variety of clinically significant infections. Three distinct species were initially recognized by MacDonell and Colwell. They were Shewanella putrefaciens, hanedai and benthica. Shewanella algae, which is the most common human clinical isolate, was believed to be a strain of Shewanella putrefaciens by some authors, and was later grouped as a separate and distinct entity. With multi-drug resistance on the rise and the lack of large-scale systemic studies, we describe a case of bacteremia caused by this rare organism. We hope to increase the awareness among care providers on the same.
