[75 years in the service of Karelia: to the anniversary of the State Medical Institution of the Republic of Karelia Bureau of Forensic Medical Examination]. / 75 let na sluzhbe Karelii: k yubileyu GBUZ RK «Byuro sudebno-meditsinskoi ekspertizy¼.

The article is dedicated to the 75th anniversary of the State Budgetary Healthcare Institution of the Republic of Karelia «Bureau of Forensic Medical Examination¼. The history of the formation of the forensic medicine service in the Republic of Karelia is briefly described. The data on the heads of the service and well-known forensic experts, the organizers of the forensic medical examination in Karelia, the course of forensic medicine of Petrozavodsk State University, the role of its employees in the work of the State Medical Institution of the Republic of Karelia «Bureau of Forensic Medical Examination¼ are presented. In addition to available literature sources, archival materials of employees and veterans of the forensic medical service of Karelia were used.

[Practical value of microorganisms for forensic purposes (on the example of microbial flora of bony remnants from the historic burial site)]. / Prakticheskoe znachenie mikroorganizmov dlya tselei sudebnoi meditsiny (na primere mikroflory kostnykh ostankov istoricheskogo zakhoroneniya).

Phenotypic signs of dominants isolated from the surface of bony remnants from the historic burial site were analyzed in order to expand data on the biodiversity of microorganisms in the microbial flora of bony remnants and to assess the possibility of using the results of microbiological analysis in the evidence base of forensic examination and forensic archaeology. It was detected that only Deuteromycota and Eubacteria colonized all types of surfaces in the samples of bone fragments from the historic burial site (with the age in the range of 90-95 years); with the abundance of micromycetes, the proportion of Eubacteria naturally decreased, while with the increased bacterial background counts the rate of micromycetes detection decreased. The insignificant amount of nutrients in the bony remnants led to the decrease in the number and biological diversity of microorganisms contaminating them; species adapted to a hard-to-reach organic substrate dominated there. During the process of bony remnants decomposition, when the conditions of their location changed, inter-species competition and specific recolonization occurred by species of microorganisms most adapted to a hard-to-reach organic substrate in the abiotic and biotic conditions of existence given. The results obtained are important for the descriptive ecology and biology of specific groups of microorganisms in the postmortem microbiome and form the basis for a more thorough study of complex communications between species of microorganisms in the necrobiome of bony remnants - in the future it will allow putting forward original hypotheses about the involvement of microbes in the circulation of matter and energy, as well as to apply the information obtained in the evidence base of forensic examination and forensic archaeology.
