In recent years, sexual assault cases have been on the rise, seriously infringing the legitimate rights and interests of women and children, causing widespread concern in society. DNA evidence has become the key evidence to prove the facts in sexual assault cases, but lack of DNA evidence or only DNA evidence in some sexual assault cases leads to unclear facts and insufficient evidence. With the emergence of high-throughput sequencing technology and the development of bioinformatics and artificial intelligence, new progress has been made in the study of human microbiome. Researchers have begun to use human microbiome for difficult sexual assault cases indentification. This paper reviews the characteristics of human microbiome, and its application value in the inferences of the body fluid stain origin, the sexual assault method, the crime time, etc. In addition, the challenges faced by the application of the human microbiome in practical case handling, the solutions and future development potential are analyzed and prospected.
近年来，性侵犯案件呈上升趋势，严重侵犯了妇女和儿童的合法权益，引起了社会的广泛关注。DNA 证据已成为证明性侵犯案件事实的关键证据，但在某些性侵犯案件中缺乏 DNA 证据或只有 DNA 证据，导致事实不清、证据不足。随着高通量测序技术的出现以及生物信息学和人工智能的发展，人类微生物组的研究取得了新的进展。研究人员开始将人类微生物组应用于难以辨认的性侵犯案件。本文综述了人类微生物组的特征及其在推断体液来源、性侵犯方法、犯罪时间等方面的应用价值。此外，还分析并展望了人类微生物组在实际案例处理中应用所面临的挑战、解决方案和未来发展潜力。
