摘要 腐生生物是引起尸体组织腐解的主要因素,研究腐败过程中微生物的演替规律是法医微生物学(forensic microbiology)的主要任务之一。尸体、环境及微生物间相互作用关系复杂,而微生物演替规律的研究依赖于从宏观角度监测各腐败节点菌群组成及群落多样性改变。随着高通量测序(high-throughput sequencing,HTS)技术的成熟和发展,不同环境中微生物菌群结构和多样性被逐一解读,同时也为探索尸体微生物打开了新的突破口。利用HTS技术挖掘尸体腐败过程中微生物群落的演替规律,诠释各种腐败现象的本质,成为法医微生物学新的研究热点,可为死亡时间(postmortem interval,PMI)推断提供新的参考依据。本文针对利用尸体微生物推断PMI的研究进行综述,基于目前HTS技术在探索腐败微生物演替规律中的应用,探讨该技术在法医微生物学研究中存在的问题及应用前景。

Abstract: Necrobiome is the main factor causing the cadaver decomposition. Studying the microbial succession during decomposition is one of the main tasks of forensic microbiology. The interactive relationships among cadaver, environment and microorganisms are complicated. The microbial succession study relies on macroscopic monitoring of community composition and the diversity change in each decomposition stage. With the maturity and development of high-throughput sequencing (HTS), the structure and diversity of microbial communities in different environments have been successively revealed. A new breakthrough to explore the cadaveric microorganisms has been opened as well. It has become the research hotspots in forensic microbiology to reveal the microbial succession in the process of cadaver decomposition and to interpret the essence of various decomposition phenomena by using HTS, which can provide a new reference for postmortem interval (PMI) estimation. The present paper reviews studies on PMI estimation by using cadaveric microorganism. Problems and application prospects of forensic microbiology studies are discussed on the basis of the current application of HTS technology in the exploration of microbial succession.
