（单词翻译）

 One of the odder aspects of infection is that microbes that normally do no harm at all sometimes get into the wrong parts of the body and "go kind of crazy," 感染有许多古怪的方面。其中之一是，有些在正常情况下完全无害的微生物，有时候会进入人体本来不该它们去的部分，

in the words of Dr. Bryan Marsh1, an infectious diseases specialist at Dartmouth-Hitchcock Medical Center in Lebanon, New Hamphire. 用新罕布什尔州莱巴嫩城达特茅斯-希契科克医疗中心的传染病专家布赖恩·马什的话来说——“有点儿发了狂”。
"It happens all the time with car accidents when people suffer internal injuries. “这种总是出现在发生了车祸，有人受了内伤的时候。
Microbes that are normally benign2 in the gut3 get into other parts of the body—the bloodstream, for instance—and cause terrible havoc4." 通常情况下肠胃里面无害的微生物就会进入身体的其他部分——比如流动的血液，产生严重的破坏作用。”
The scariest, most out-of-control bacterial5 disorder6 of the moment is a disease called necrotizing fasciitis 眼下，最罕见的也是是无法控制的细菌引起的疾病，是一种会导致坏死病的筋膜炎。
in which bacteria essentially7 eat the victim from the inside out, devouring8 internal tissue and leaving behind a pulpy9, noxious10 residue11. 细菌吞噬内部组织，留下一种糨糊状的有毒残渣，实际上把病人从里到处吃掉。
Patients often come in with comparatively mild complaints—a skin rash and fever typically—but then dramatically deteriorate12. 起初，病人往往只是稍有不舒服——通常是身上出疹，皮肤发热——但接着就急剧恶化。
When they are opened up it is often found that they are simply being consumed. 打开一看，往往发现病人正被完全吃掉。
The only treatment is what is known as "radical13 excisional surgery"—cutting out every bit of infected area. 唯一的治疗办法是所谓的“彻底切除手术”——即把所有感染部位全部切除。
Seventy percent of victims die; many of the rest are left terribly disfigured. 70%的病人死亡，许多幸存者最后严重毁形。
The source of the infection is a mundane14 family of bacteria called Group A Streptococcus, which normally do no more than cause strep throat. 感染原是一种名叫A群链球菌的普通细菌家族，通常不过引起链球菌咽喉炎。
Very occasionally, for reasons unknown, some of these bacteria get through the lining15 of the throat and into the body proper, where they wreak16 the most devastating17 havoc. 在极少的情况下，由于不明原因，这类细菌有的会钻进咽喉壁里，进入人体本身，造成最严重的破坏作用。
They are completely resistant18 to antibiotics19. 它们完全能抵御抗生素。
About a thousand cases a year occur in the United States, and no one can say that it won't get worse. 这种情况美国每年发生大约1000例，谁也说不准情况是不是会变得更严重。
