Cleaning is fundamental to infection control. This report demonstrates that a Staphylococcus aureus biofilm is significantly more difficult to remove than dried planktonic bacteria. A single wiping action removed >99.9% (>3 log₁₀) of dried planktonic bacteria, whereas only 1.4 log₁₀ of biofilm (96.66%) was removed by 50 wiping actions with a standardized wiping process.

难以去除干燥表面上的生物膜

清洁对于控制感染至关重要。该报告表明，金黄色葡萄球菌生物膜比干燥的浮游细菌更难去除。一次擦拭动作可去除> 99.9％（> 3 log ₁₀）的干燥浮游细菌，而通过标准化擦拭过程进行的50次擦拭动作仅可去除1.4 log ₁₀的生物膜（96.66％）。
