Septic shock is still associated with high morbidity and mortality. Early aggressive care and appropriate empiric antibiotic therapy remain the cornerstone of therapy and are important for improving outcomes. Infections with rare organisms may complicate diagnosis and make initiation of appropriate antibiotics challenging. Hence, knowledge of rare infections and their sensitivity patterns is imperative for managing such cases. Shewanella spp. are facultative anaerobic gram-negative bacilli which are primarily found in marine environments. They have increasingly been recognized to cause human infections, which may rarely be life-threatening. Here, we present a case of septic shock secondary to Shewanella algae bacteremia.
