Methods: Bacterial culture and detection were conducted on samples on mobile phone from 100 randomly selected students at a college in Dali. Results: Bacterial pollution was serious in students mobile phone, the total number of bacteria detection rate was 96% （96/100 ）, and the total number of bacteria pollution exceed the standard rate of 25% （25/100 ）. Exceed standard rate of total bacteria on keypad mobile phone was higher than that on the touch screen mobile phone （P0.05 ）. The positive rate of coliform group was 24% （24/100 ）, and the coliform group detection rate of male case
