Abstract
Microbial diversity's potential has been investigated in medical and therapeutic studies throughout the last few decades. However, its usage in forensics is increasing due to its effectiveness in circumstances when traditional approaches fail to provide a decisive opinion or are insufficient in forming a concrete opinion. The application of human microbiome may serve in detecting the type of stains of saliva and vaginal fluid, as well as in attributing the stains to the individual. Similarly, the microbiome makeup of a soil sample may be utilised to establish geographic origin or to associate humans, animals, or things with a specific area, additionally microorganisms influence the decay process which may be used in depicting the Time Since death. Further in detecting the traces of the amount and concentration of alcohol, narcotics, and other forensically relevant compounds in human body or visceral tissues as they also affect the microbial community within human body. Beside these, there is much more scope of microbiomes to be explored in terms of forensic investigation, this review focuses on multidimensional approaches to human microbiomes from a forensic standpoint, implying the potential of microbiomes as an emerging tool for forensic investigations such as individual variability via skin microbiomes, reconstructing crime scene, and linking evidence to individual.

Abstract
Through experimental reproduction of the decomposition process using the cadaver of rabbit Oryctolagus sp., the dynamics of cadaver microflora was studied; the dominant bacterial taxa were isolated in pure culture and identified; their ecological and trophic profiles and biodiversity were described based on the values of Simpson and Menchinic ecological indices. The dependence of cadaver rotting and skeletonization rate on the taxonomic profile of microorganisms, decomposition period, and abiotic environmental factors (temperature, acidity, soil moisture) was demonstrated. The data obtained contribute to justifying the use of microbiological methods in forensic practice. To establish objective causality patterns of microbial transformation of organic matter in nature, further targeted study of ecological patterns of cadaveric microflora is necessary.

Abstract
Forensic microbiology, also known as the microbiology of death, is an emerging branch of science that is still underused in criminal investigations. Some of the cases might be difficult to solve with commonly-used forensic methods, and then they become an operational field for microbiological and mycological analysis. The aim of our review is to present significant achievements of selected studies on the thanatomicrobiome (microorganisms found in the body, organs and fluids after death) and epinecrotic community (microorganisms found on decaying corpses) that can be used in forensic sciences. Research carried out as a part of the forensic microbiology deals with the thanatomicrobiome and the necrobiome - communities of microorganisms that live inside and outside of a putrefying corpse. Change of species composition observed in each community is a valuable feature that gives a lot of information related to the crime. It is mainly used in the estimation of post-mortem interval (PMI). In some criminal investigations, such noticeable changes in the microbiome and mycobiome can determine the cause or the actual place of death. The microbial traces found at the crime scene can also provide clear evidence of guilt. Nowadays, identification of microorganisms isolated from the body or environment is based on metagenome analysis and 16S rRNA gene amplicon-based sequencing for bacteria and ITS rRNA gene amplicon-based sequencing for fungi. Cultivation methods are still in use and seem to be more accurate; however, they require much more time to achieve a final result, which is an unwanted feature in any criminal investigation.

Abstract
The aim of this work is to monitor the state of the proteolytic community in time and space for the subsequent development of approaches to an objective assessment of the late postmortem period. The study proposes a combination of standard bacterioscopic and bacteriological research methods with methods of molecular biology and genetics, which make it possible to identify species and strains of mammalian corpses' proteolytics at the level of specific DNA or RNA. On the basis of phenotypic traits and a comparative analysis of the nucleotide sequences of genes encoding 16S rRNA, the species belonging of the isolated strains was proved. The set of methods' combination, including traditional microbiological analysis and molecular genetic studies, seems promising both for the purpose of substantiating and widespread use of microbiological methods in forensic medical practice, and for development an objective scientific base for establishing the cause-and-effect patterns of microbial transformation of organic matter in nature.

Abstract
Recent advances in genetic data generation, through massive parallel sequencing (MPS), storage and analysis have fostered significant progresses in microbial forensics (or forensic microbiology). Initial applications in circumstances of biocrime, bioterrorism and epidemiology are now accompanied by the prospect of using microorganisms (i) as ancillary evidence in criminal cases; (ii) to clarify causes of death (e.g., drownings, toxicology, hospital-acquired infections, sudden infant death and shaken baby syndromes); (iii) to assist human identification (skin, hair and body fluid microbiomes); (iv) for geolocation (soil microbiome); and (v) to estimate postmortem interval (thanatomicrobiome and epinecrotic microbial community). When compared with classical microbiological methods, MPS offers a diverse range of advantages and alternative possibilities. However, prior to its implementation in the forensic context, critical efforts concerning the elaboration of standards and guidelines consolidated by the creation of robust and comprehensive reference databases must be undertaken.

Abstract
Post-mortem microbiology (PMM) is an important tool in forensic pathology, helping to determine the cause and manner of death, especially in difficult scenarios such as sudden unexpected death (SD). Currently, there is a lack of standardization of PMM sampling throughout Europe. We present recommendations elaborated by a panel of European experts aimed to standardize microbiological sampling in the most frequent forensic and clinical post-mortem situations. A network of forensic microbiologists, pathologists and physicians from Spain, England, Belgium, Italy and Turkey shaped a flexible protocol providing minimal requirements for PMM sampling at four practical scenarios: SD, bioterrorism, tissue and cell transplantation (TCT) and paleomicrobiology. Biosafety recommendations were also included. SD was categorized into four subgroups according to the age of the deceased and circumstances at autopsy: (1) included SD in infancy and childhood (0-16 years); (2) corresponded to SD in the young (17-35 years); (3) comprised SD at any age with clinical symptoms; and (4) included traumatic/iatrogenic SD. For each subgroup, a minimum set of samples and general recommendations for microbiological analyses were established. Sampling recommendations for main bioterrorism scenarios were provided. In the TCT setting, the Belgian sampling protocol was presented as an example. Finally, regarding paleomicrobiology, the sampling selection for different types of human remains was reviewed. This proposal for standardization in the sampling constitutes the first step towards a consensus in PMM procedures. In addition, the protocol flexibility to adapt the sampling to the clinical scenario and specific forensic findings adds a cost-benefit value.
