摘要:
目的 了解上海市某区9 家影剧院使用3D眼镜的清洗及消毒状况。 方法 选取提供顾客使用非一次性3D眼镜的9 家影剧院进行调查,运用涂抹采样法随机采集样品并检测细菌总数、霉菌和部分致病微生物,并计算合格率。 结果 共采集样品69 件,33 件未消毒样品细菌总数检出率为45.45%,霉菌检出率为9.09%,36 件已消毒样品细菌总数检出率为41.67%,霉菌检出率为8.33%;金黄色葡萄球菌、沙门菌、志贺菌、致病性弧菌等致病菌及腺病毒、带状疱疹病毒、单纯疱疹病毒Ⅰ型和单纯疱疹病毒Ⅱ型等病毒检出率为0。 结论 经过清洗及消毒的客用3D眼镜细菌总数和霉菌检出率有所降低,影剧院加强对3D眼镜清洗消毒工作的管理有重要的公共卫生学意义。 Abstract:Objective To investigate the conditions of cleansing and disinfecting 3D glasses in nine movie theatres in a district of Shanghai. Methods Nine movie theatres that provided reusable 3D glasses for customers were selected to detect total bacterial count, mould, and selected pathogenic bacteria using random swab sampling techniques, and to calculate qualified rate. Results A total of 69 samples were collected. Of the 33 samples without disinfection, the positive rates were 45.45% for total bacterial count and 9.09% for mould. Of the 36 samples with disinfection, the detection rates were 41.67% for total bacterial count and 8.33% for mould. No pathogenic bacteria such as Staphylococcus aureus, Saimonella, Shigella, and pathogenic Vibrio were detected, nor were viruses such as adenovirus, herpes zoster virus, herpes simplex virus type1, and herpes simplex virus type2. Conclusion The numbers of total bacteria and mould collected from disinfected 3D glasses are slightly reduced. Strengthening the management of cleaning and disinfection for 3D glasses is of great public health significance.
