Abstract

In the forensic reconstruction of crime scene activities, the identification of biological traces and their bodily origin are valuable evidence that can be presented in court. While several presumptive and confirmatory tests are currently available, the limitations in specificity and sensitivity have instigated a search for alternative methods. Bacterial markers have been proposed as a novel approach for forensic body fluid/tissue identification. Bacteria are not only ubiquitous throughout the human body, but also, as shown by recent
