摘要 目的 探讨示指菌群和接触物(手机触摸屏、个人办公桌桌面)表面菌群之间的关联性。 方法 采集10名志愿者的示指、手机触摸屏、个人办公桌桌面的菌群,通过宏基因组PCR扩增技术建立肠道细菌基因间重复序列(enterobacterial repetitive intergenic consensus,ERIC)-PCR指纹图谱。 结果 7名志愿者的示指与手机触摸屏菌群ERIC-PCR指纹图谱对应吻合,且各志愿者个体之间ERIC-PCR指纹图谱互不相同;3名志愿者的示指菌群与个人办公桌桌面菌群ERIC-PCR指纹图谱对应吻合,其余7名志愿者的示指菌群与个人办公桌桌面菌群ERIC-PCR指纹图谱不完全吻合,但分别存在大小一致的条带。 结论 示指所携带的细菌菌群具有一定个体特异性,示指接触手机触摸屏、办公桌桌面后残留下来的菌群,可作为潜在的法医学鉴定的新型生物样本。

Abstract: Objective To explore the bacteria relevance between index fingers and contactant’ surfaces (mobile phone touch screen and desktop of personal office table). Methods Bacteria were collected from the index fingers, mobile phone touch screen and desktop of personal office table of 10 volunteers. Enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprint was established by PCR amplification technique of metagenome. Results There were 7 volunteers’ ERIC-PCR fingerprints of index fingers matched that took from the mobile phone touch screens, and different from each other. There were 3 volunteers’ ERIC-PCR fingerprints of index fingers matched that took from desk top of personal office table, and other 7 volunteers’ ERIC-PCR fingerprints did not match perfectly with that took from desk top of personal office table, but had at least one similar band for both. Conclusion The bacteria on index finger shows individual specificity, which on mobile phone touching screen and personal desktop may be a new biological sample of forensic identification.
