Tissierella Praeacuta Infection in the Setting of Chronic Sacral Wounds.

is a gram negative anaerobe with few documented cases of human infections. This case illustrates a patient who was admitted for infected chronic sacral and ischial decubitus wounds. BACT/ALERT blood culture system using Matrix Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) (Bruker Daltonics, Billerica, USA) was employed ultimately identifying as the causative organism. The suspected source of the pathogen was presumed to be from his infected decubitus wounds.
