Bordetella trematum sepsis with shock in a diabetic patient with rapidly developing soft tissue infection.

Bordetella is a gram-negative, glucose non-fermenting bacillus, consisting of many host-associated species. B. trematum has previously been identified in wound infections, but rarely known to be a source of bacteremia. Currently, 16S rRNA sequencing represents the reference standard method by which identification is made. Herein, we present a case of fatal B. trematum bacteremia with septic shock. The presumed primary site of the infection was a rapidly developing left leg deep soft tissue infection without necrotizing fasciitis. B. trematum should now be considered as a significant pathogen in sepsis.
