Bacteremia Caused by Clostridium symbiosum in University Clinical Hospital Mostar: A Case Report

<i>Clostridium spp</i>. is one of the most common anaerobic pathogens that cause bacteremia. It is often associated with intraabdominal sepsis due to trauma or surgery, and malignancies or diabetes. This is the presentation of a <i>Clostridium symbiosum</i> (<i>C. symbiosum</i>)bacteremia in a 66-year-old woman with a history of bladder cancer and radical cystectomy with ureterosigmoidostomy. The isolate was identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS, Bruker, Ettlingen, Germany). The application of new methods, such as MALDI-TOF MS and 16S rRNA gene sequencing, has made it possible to provide rapid and reliable identification of diverse anaerobic species and timely information about their role in infections.
