| 摘 要： | 目的解决蝇类成虫、蛹和蛆快速、准确鉴定的难题。方法随机采集潍坊地区人尸周围环境中的蝇类成虫、蛹和蛆,提取其mtDNA,经PCR扩增、产物检测与纯化、测序等,比较其序列差异。结果六种常见嗜尸性蝇类相互之间序列差异明显,同一种蝇的成虫、幼虫、蛹之间未见差异。结论mtDNACOI区序列分析可作为法医学嗜尸性蝇类种属鉴别的可靠方法。

| Abstract: | Objective To identify sarcosaphagous flies and their larvae, pupa. Methods sarcosaphagous flies and their larvae, pupas were collected from human corpses and their surroundings in the Weifang city. A 304 bp region in COI gene was analyzed by mtDNA sequencing. Results The studied region showed no sequence divergence within same species and significant difference were found between different species in all samples. Conclusion It is a practical approach to identify these Sarcosaphagous flies and their larvae, pupas by sequence analysis of the 304 bp region of the COI in mtDNA. |
