紫外线照射作为饮用水和废水处理的消毒程序越来越重要。由于水是甲型肝炎病毒的主要传播途径之一，因此HAV对紫外线的敏感性特别令人感兴趣。MS-2大肠杆菌噬菌体的大小和结构与甲型肝炎病毒相似，易于操作，因此可作为评价水质和评价水处理工艺质量的指示生物。将甲型肝炎病毒和MS-2大肠杆菌噬菌体悬浮于0.9%氯化钠溶液中，并在20 ml石英比色皿中于254 nm处照射。对于四个对数单位的减少率，MS-2需要比HAV高三倍的UV剂量。
Ultraviolet irradiation is gaining importance as a disinfection procedure for drinking water and in waste water treatment. Since water is one of the main transmission routes of hepatitis A virus the susceptibility of HAV to UV rays is of special interest. MS-2 coliphage resembles HAV in size and structure, is easy to handle, and might tlierefore serve as indicator organism for the assessment of water quality and for evaluating the quality of water treatment processes. Hepatitis A virus and MS-2 coliphage were suspended in 0.9% sodium chloride solution and were irradiated in a 20-ml quarz cuvette at 254 nm. For a reduction rate of four log units a three times liigher UV dose was required with MS-2 than with HAV.
