摘要:本文通过对不同使用者手机微生物污染情况和使用习惯调查,初步了解校园手机微生物污染状况,并分析造成手机微生物污染的原因所在,提出有效的防治方案。实验结果表明,本次所检测的80台手机,基本都被微生物污染,其中细菌总数污染比较严重,大肠杆菌,金黄色葡萄球菌,霉菌,酵母菌携带量也较多。在被检的80台手机中,学生手机的微生物污染情况样本占被金黄色葡萄球菌污染样本占15%,被酵母菌污染样本占25%,被大肠杆菌污染样本阳性率5%;教师手机金黄色葡萄球菌被污染样本占10%,酵母菌样本占27.5%,霉菌样本占35%,大肠杆菌阳性率30%。菌落数目无法计数35%。使用习惯调查显示,饮食中使用手机是手机带菌的主要原因。

Abstract: In this paper, by phone microbial contamination of the different user habits survey, preliminary analysis of the reason to cause the phone to microbial contamination, and propose solutions. The experimental results show that this check detected 80 mobile phones, teachers and students of the mobile phone carrier in general E. coli, Staphylococcus aureus, fungi, yeast infections, microbial contamination in samples of students' mobile phones accounted for 15% of the golden Staphylococcus contaminated sample accounted for 15% of the sample of yeast contamination accounted for 25%, contaminated with E. coli samples accounted for 5% of the positive bacteria, the E. coli samples accounted for the positive bacteria accounted for 95% of teachers phone Staphylococcus aureus contaminated sample accounted for 10 %, yeast samples of 27.5%, accounted for 35% of mold samples, accounted for 30% of the E. coli-positive bacteria samples, samples of E. coli-negative bacteria accounted for 70%. The number of colonies can not count 35%. The survey shows usage habits, diet, use of mobile phones is the main reason of the mobile phone carrier.
