Mycobacterium tuberculosis strain Erdman, M. bovis (BCG), and M. phlei showed a 1- to 2-log drop in viability after exposure to ultraviolet light compared to a 5-log drop over the same period for Staphylococcus albus, Listeria monocytogenes, Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis, and Serratia marcescens. L. monocytogenes showed an initial resistance to ultraviolet inactivation, but later the inactivation rate increased sharply. The significance of these findings with regard to the use of S. marcescens as a test organism for determining the bactericidal efficiency of ultraviolet lamps used to sterilize equipment contaminated with tubercle bacilli is discussed.
结核分枝杆菌 Erdman 菌株、牛分枝杆菌(卡介苗)和草分枝杆菌在暴露于紫外线后,其活力下降了 1 至 2 个对数级,而同期白色葡萄球菌、单核细胞增生李斯特菌、大肠杆菌、铜绿假单胞菌、肠炎沙门氏菌和粘质沙雷氏菌的活力下降了 5 个对数级。单核细胞增生李斯特菌对紫外线灭活表现出初始抗性,但随后灭活速率急剧增加。讨论了这些发现对于使用粘质沙雷氏菌作为测试生物来确定用于对被结核杆菌污染的设备进行消毒的紫外线灯杀菌效率的意义。
