背景:良好的牙刷和毛巾处理是个人卫生的重要考虑因素。因此,这项研究旨在评估发展研究大学的学生如何处理牙刷和毛巾,以及这些人员卫生材料的微生物质量的后果。
方法:收集总共100个交换样品(50个牙刷和50个毛巾)用于微生物分析。对收集样本的学生进行问卷调查,以确定他们如何处理牙刷和毛巾的信息。分别用MacConkey琼脂和甘露醇盐琼脂分离大肠杆菌和金黄色葡萄球菌,和头孢西丁用于鉴定耐甲氧西林金黄色葡萄球菌菌株。
结果:E.大肠杆菌存在于所有样本毛巾中,而98%的牙刷样品含有大肠杆菌。发现百分之二的受访者把牙刷放在澡堂,44%的人将它们不封闭在房间里,54%的人将它们封闭在房间里(54%)。此外,48%的受访者每周洗一次毛巾,24%每两周洗一次,20%每月一次,8%每三个月一次。此外,52%的人在房间里干毛巾,而48%的人在房间外面干毛巾。对于毛巾和牙刷,金黄色葡萄球菌的发生率分别为96%和94%。在分离的金黄色葡萄球菌中,33.3%的样品毛巾和12.8%的牙刷含有耐甲氧西林金黄色葡萄球菌。
结论:这项研究发现,如果学生的个人卫生行为没有改变,他们就有感染传染病的风险。
BACKGROUND: Good toothbrush and towel handling are important considerations in personal hygiene. Thus, this study sought to assess how students of the University for Development Studies handle their toothbrushes and towels and the consequence of that with regards to the microbial quality of these personnel hygiene materials.
METHODS: A total of 100 swap samples were collected (50 toothbrushes and 50 towels) for microbial analysis. Questionnaires were administered to students from whom samples were collected to ascertain information on how they handle toothbrushes and towels. MacConkey agar and Mannitol Salt agar were used to isolate E. coli and S. aureus respectively, and cefoxitin used to identify the methicillin-resistant S. aureus strains.
RESULTS: E. coli was present in all sampled towels, while 98% of the sampled toothbrushes contained E. coli. It was found that 2% of the respondents kept their toothbrushes in bathhouses, 44% kept them unenclosed in rooms and 54% kept them enclosed in rooms (54%). Also, 48% of the respondents washed their towels once a week, 24% washed once every two weeks, 20% once every month and 8% once a trimester. Moreover, 52% dried their towels in rooms while 48% dried them outside rooms. The occurrence of S. aureus was 96% and 94% respectively for the towels and toothbrushes. Of the S. aureus isolated, 33.3% of sampled towels and 12.8% of the toothbrushes contained methicillin-resistant S. aureus.
CONCLUSIONS: This study found that, students are at risk of contracting infectious disease if their personal hygiene behaviours do not changed.
