The analysis of the microbiome is gaining more interest in the forensic community, with applications going from post-mortem interval (PMI) estimation to human identification. The composition of the human microbiota is strongly affected by sex, lifestyle, health condition and geographical location, and it has been shown to be unique to each single individual, making the analysis of the human microbiome a strong alternative to the forensic genotyping for human identification purposes. The microbial community is also a good target for the estimation of PMI, due to the successive changes in microbial population that are specific at different decomposition stages. The aim of the project is to explore the oral microbiome of dead human donors collected at different decomposition stages, to get insights on the changes involved with the decomposition and to identify which one will be the best microbial source between oral cavity and teeth (dental calculus). Furthermore, the project will also involve a comparative study between the oral and the skin microbiome of living individuals originated from two different countries (UK and Italy), to clarify if groups of individuals sharing the same geographical location will have similar microbiomes or not, and to finally identify potential microbial markers for identification purposes. Finally, part of the study will also involve the amplification and the analysis of the microbial DNA that has been co-extracted with the human DNA, using different methodologies, from real past forensic caseworks and which has been preserved frozen after the extraction. The aim is to clarify if the DNA extracts could be informative from a microbial point of view, and if they should be preserved after the closure of the case due to their potential to reveal new important forensic information once specific microbial markers for PMI estimation and personal identification will be completely unveiled.
