The latest reports on the subject of forensic microbiology indicate that it is possible to link a perpetrator of an offence to the evidence, based on molecular analysis of microbiological material. The microbiome of human epidermis is known to be species- and individual-specific. This knowledge can be used towards finding a match between the object (e.g. electronic device) and the user, based on the individual-specific microbiome deposited onto the object’s surface. The DNA fingerprinting-based methods were used to compare similarities in the structures of bacterial communities collected from the epidermis of 14 study subjects and the housings of their mobile phones. This study was based on the Polymerase Chain Reaction – Denaturing Gel Electrophoresis method. The results obtained revealed a high degree of similarity between the structure of bacterial genotypes present on the users’ epidermis and the microbiomes recovered from their mobile phones. PCR-DGGE can be used as the screening method, preceding the additional confirmatory analyses.
