Microscopic fungi on the corpse – Promising tool requiring further research

Abstract

Forensic microbiology is a relatively new area of forensic sciences. It considers the potential of microorganisms to be used in criminal investigations. As most studies involve the role of bacteria in fields like post-mortem interval estimation, personal identification or geolocation, the data on the role of fungi is comparatively scarce. Forensic mycology involves the application of fungi and their structures in forensic cases. The aim of this review is the evaluation of the current state of knowledge on fungi associated with human cadavers and their possible role in estimating the time since death. In accordance with the available reports, we focused on the relation between microscopic fungi isolated from human corpses and the cadaver condition e.g., the stage of decomposition. We also emphasised the contrast between the reported methodologies and attempted to standardise research methods in forensic mycology from sample collection to its storage, mycological analysis and identification of the obtained fungal cultures. Moreover, the potential usage of microscopic fungi in criminal cases was discussed based on various case reports.
