Application Bacteriology in Forensic Science Using Animal Model
Words • 2430
Pages • 10
Over the past century of scientific inquiry into the process of decomposition, nearly every mammal (and other taxa) has been studied. Forensic microbiologists are developing new applications to investigate the dynamic and coordinated changes in microbial activity that occur when a human host dies. There is currently a paucity of explorations of the thanatomicrobiome (thanatos-, Greek for death) and epinecrotic communities (microbial communities residing in and/or moving on the surface of decomposing remains). Ongoing studies can help clarify the structure…...
