Dangerous, Deadly Superbugs 危险而致命的超级病菌
These germs can resist most anything
大部分药物都杀不死这些细菌
SC080404
Alison Lawson endured a long winter a year ago when her daughter Genevieve's ear infection lasted for months without successful treatment. After analyzing Genevieve's ear fluid, her doctor discovered the reason: Genevieve was infected with a superbug that had developed resistance to all child-approved antibiotics.
When antibiotic drugs were first introduced in the 1940s, they revolutionized health care, and illnesses that previously had been life-threatening could be treated with much more success. Unfortunately, in the decades since then, the overuse of antibiotics has led to antibiotic-resistant superbugs.
Antibiotic resistance can develop in different ways. When antibiotics enter the body, they attack bacteria, either destroying them or making them unable to multiply. Any bacteria that successfully resist the antibiotics can then multiply and spread. Bacteria can also become antibiotic-resistant by trading DNA with other germs. When bacteria become immune to several antibiotics, they are called superbugs.
Last year, in Rochester, New York, several children suffered from the same ear infection Alison Lawson's daughter had. The lucky ones, including Genevieve, were successfully treated with an antibiotic approved only for adult use; however, one unlucky child ended up with permanent hearing damage.


    爱莉森?洛桑一年前度过了一个漫长的冬天,当时她的女儿吉娜薇的耳朵感染,病况持续数月都没能治癒。医生分析吉娜薇的耳水後,找到了原因:吉娜薇感染了一种超级病菌,该病菌对所有准许儿童使用的抗生素都有抗药性。
    抗生素於一九四0年代开始使用时,为医疗保健带来重大变革,过去威胁人命的疾病得以有更有效的治疗结果。不幸的是,之後数十年间,滥用抗生素已导致具抗药性的超级病菌出现。
    细菌的抗药性可能会经由几种不同方式产生。抗生素进入人体後,会对细菌发动攻击,把细菌杀死或使细菌无法繁殖。任何细菌只要能抵挡抗生素就能繁殖及散播。细菌也会透过与他种细菌交换去氧核糖核酸而产生抗药性。一旦细菌对多种抗生素免疫,就会被称为超级病菌。
    去年,在纽约州罗契斯特市,好几个孩童跟爱莉森?洛桑的女儿一样耳朵受到感染。包括吉娜薇在内的幸运孩童经由成人用抗生素治疗後痊癒,然而,有个孩童的听力却不幸永久受损。

SC080405
Doctors blame the development of superbugs in part on the misuse of antibiotics. When a child has the flu, a cold, a sore throat or an ear infection, concerned parents often ask for antibiotics to speed their child's recovery. But prescribing antibiotics may not be the best solution: For example, viruses that cause the flu and colds don't respond to antibiotics. When antibiotic treatment is necessary, doctors advise taking the entire course ─ not stopping early because one "feels better" ─ so the drugs can have their full effect.
Children aren't the only targets of superbugs. Health care facilities such as hospitals and nursing homes commonly deal with all kinds of infectious diseases, including superbugs. One drug-resistant strain of bacteria, called MRSA, can be spread by contaminated hands and medical equipment. It's reported to have caused approximately 18,500 deaths in 2005 in the United States. Recently, a newer strain of MRSA has been scaring people because it is spreading outside of hospitals in places such as schools, athletic facilities and jails.
Superbugs have the potential to bring medicine back to a time before antibiotics, when doctors couldn't successfully treat many serious diseases. However, by using antibiotics wisely, the general public can join scientists in the challenge to stop them.

    医生将超级病菌出现的原因部份归咎於滥用抗生素。小孩得了流感、感冒、喉咙痛或耳朵感染,心急如焚的家长常要求医生开抗生素,让孩子尽快复原,不过开抗生素未必是最好的疗法:例如引发流感与感冒的病毒对抗生素就没有反应。一旦使用抗生素「有」其必要,医生会建议整个疗程都要服用,不要因为病人「觉得好些了」就提早中断服用,才能让药物完全发挥功效。
    儿童并非超级病菌的唯一肆虐对象。医疗院所如医院与疗养院常应付各种传染病,其中也包括超级病菌。一种叫做 MRSA*的抗药性菌种会经由被污染的手和医疗器材向外散播。(*译注:即抗药性金黄色葡萄球菌。)据称二00五年,这种病菌在全美各地夺走约一万八千五百人的性命。最近 MRSA 有种可怕的新菌株令人闻之色变,它会在医院之外的地方散播,例如学校、运动场所和监狱。
    超级病菌很可能会使医学回到抗生素问世前、医生对许多恶疾都束手无策的时代,然而,藉由明智地使用抗生素,社会大众可以和科学家并肩作战,进而阻止超级病菌的危害。
