“我爱洗澡，皮肤好好，哦哦哦哦...”这首熟悉的旋律让我们回忆起来的是童年的美好，可是下面这篇报导，我想对于洗澡这件事情，从此不再简单了。浴室喷头里隐藏着可能致命的细菌，我们的淋浴式洗澡方式该何去何从？

　浴室杀手：可能致死的分支杆菌
   
    浴室喷头隐藏细菌，特别是分支杆菌Mycobacterium avium，对免疫功能损伤、囊性纤维化或是艾滋病(AIDS)病人、接受癌症治疗或近期器官移植病人就生死攸关了。
   
    In what may be the scariest shower news since Alfred Hitchcock's "Psycho," a study says shower heads can harbor tiny bacteria that come spraying into your face when you wash. People with normal immune systems have little to fear, but these microbes could be a concern for folks with cystic fibrosis or AIDS, people who are undergoing cancer treatment or those who have had a recent organ transplant.
   
    Researchers at the University of Colorado tested 45 showers in five states as part of a larger study of the microbiology of air and water in homes, schools and public buildings. They report their shower findings in Tuesday's edition of Proceedings of the National Academy of Sciences.
   
    In general, is it dangerous to take showers? "Probably not, if your immune system is not compromised in some way," lead author Norman R. Pace says. "But it's like anything else — there is a risk associated with it."
   
    The researchers offer suggestions for the wary, such as getting all-metal shower heads, which microbes have a harder time clinging to.
   
    Still, shower heads are full of nooks and crannies, making them hard to clean, the researchers note, and the microbes come back even after treatment with bleach.People who have filtered shower heads could replace the filter weekly, added co-author Laura K. Baumgartner. And, she said, baths don't splash microbes into the air as much as showers, which blast them into easily inhaled aerosol form.
   
    It doesn't seem as frightening as the famous murder-in-the-shower scene in Hitchcock's classic 1960 movie. But it's something to be reckoned with all the same.
   
    The bugs in question are Mycobacterium avium, which have been linked to lung disease in some people.
