Topic Information

Dear Colleagues,

Numerous studies relate differences in microbial communities to human health and disease. However, little is known about microbial changes that occur postmortem or the possible applications of microbiome and proteome analysis in the field of forensic science.

The human microbiota is a highly dynamic system that can be affected by many factors, including spatial and temporal components, which are critical because they are associated with factors such as age, sex, life habits, geographical location, occupation, or interaction with other people. From a forensic point of view, microorganisms are essential for their role in the process of cadaveric decomposition. Additionally, microorganisms can provide evidence in many different forensic scenarios, including investigations into sexual assault when there is no other type of evidence available. Given the enormous forensic potential presented by microbial analysis, there is a need to develop standardized operating procedures for the collection, analysis, and interpretation of microbial evidence, as well as to create solid and complete databases for full implementation in the forensic context, thus allowing the use of microorganisms as auxiliary evidence in criminal cases, to clarify the causes of death, provide identification and geolocation information or to estimate the postmortem interval, among other uses. Several studies point to a promising future for microbiome analysis in the different fields of forensic science, opening up an important new area of research.

On the other hand, in recent years, the proteome has a great potential in both clinical and forensic research. In many circumstances, death’s causes cannot be precisely defined by the circumstances, date of death, or the lack of markers that facilitate clinical practice. The postmortem variation of proteins involved in vital cascades could be of great help in determining the cause of death and even the postmortem interval.

Background. Sudden unexpected death (SUD) is one of the most important and worthy investigation case profiles in emergency medicine and forensic pathology. Sudden unexpected deaths in adults (SUDA) are frequently caused by cardiac events, while infections usually cause those in infants younger than one year (SUDI), and to a lesser extent, in children older than one year (SUDC). However, in some instances of children under the age of one dying (SIDS), a cause is not discovered despite a thorough investigation that includes a review of clinical history, examination of the death scene, and a complete autopsy. Several studies demonstrate that the microbiome influences host immunity, alters susceptibility to viral respiratory infections, and has a vital role in various health, disease, and death outcomes. The main objective of this systematic review was to compile and offer a complete vision of the main lines of research on microbiome and sudden death that have emerged in recent years and their relationship with forensic sciences, as well as the possible contributions or limitations in the field of forensic sciences. Methods. Following PRISMA principles, a systematic evaluation of the microbiome and sudden death in forensic science was conducted. In this review, our study classified the sudden deaths as SUDA, SUDI, and SIDS. Results. The role of microbiome research in sudden death is discussed in this review. Various studies have linked the detection of different bacteria or viruses as a probable cause of sudden death. Bacteria analysed differ between studies that used autopsy specimens from deaths classified as SUDA, SUDI, and SIDS, or, except in the case of Staphylococcus aureus and Escherichia coli, which have been analysed in both SUDI and SIDS autopsies. In the case of viruses, only Cytomegalovirus has been analysed in both SIDS and SUDI cases. However, all the viruses studied are respiratory viruses found in samples of nasopharyngeal or lung fluid. Conclusions. Although the application of the microbiome in sudden death and other fields of forensic science is still in its early stages, a role of the microbiome in sudden deaths cannot be ruled out, but we cannot conclude that it is a significant factor either.

Forensic microbiomics is a promising tool for crime investigation. Geolocation, which connects an individual to a certain place or location by microbiota, has been fairly well studied in the literature, and several applications have been found. The aim of this review is to highlight the main findings in this field, including the current sample storage, DNA extraction, sequencing and data analysis techniques that are being used, and its potential applications in human trafficking and ancient DNA studies. Second, the challenges and limitations of forensic microbiomics and geolocation are emphasised, providing recommendations for the establishment of this tool in the forensic science community.
