OBJECTIVES: 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.
CONCLUSIONS: 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.
