盘尼西林改变了一切。过去致命的感染突然间能被迅速地治癒。但是玛芮恩·麦肯纳提出了令人省思的观点：我们已经浪费掉抗生素为人类所带来的优势。具有抗药性细菌的出现，意味著我们正在步入”后抗生素的世界“。这是一件不好的发展。然而，仍然有许多我们可以做的......如果从现在开始。

The nurses there recognized right away
that he had an infection,

那里的护士马上看出他得了感染，
01:21
what at the time they would
have called "blood poisoning,"

21
69905

尽管他们没有说什么，
01:28
they would have known right away

the lifestyle diseases that afflict us
in the West today.

43
136032
4088
不是现在折磨我们的生活习惯病
02:32
They didn't die of those diseases
because they didn't live long enough
because they didn't live long enough
44
140490
3739
他们没有患上那些疾病是因为他们活不到
得那些疾病的年龄
02:36

02:38
They died of injuries --

02:48
and most of the time from infection,
50
156465
3381
很多时候，是因为得了感染，
02:51
which finished what those injuries began.
51
159846
3506
因伤势造成的感染
02:56
All of that changed
when antibiotics arrived.
when antibiotics arrived.
52
164492
3532
当抗生素到来时，一切都变了
03:00
Suddenly, infections that had
been a death sentence
been a death sentence
53
168599
3599
曾经意味着死亡的感染突然
03:04
became something
you recovered from in days.
you recovered from in days.
54
172198
3390
变成了几天就能恢复的病
03:07
It seemed like a miracle,
55
175588
3042
它就像奇迹
03:10
and ever since, we have been living inside
the golden epoch of the miracle drugs.
the golden epoch of the miracle drugs.
56
178630
6324
从此以后，
我们就一直生活在特效药的黄金时代中
我们就一直生活在特效药的黄金时代中
03:17
And now, we are coming to an end of it.
57
185294
3947
现在，它即将结束了
03:21
My great uncle died in the last days
of the pre-antibiotic era.
of the pre-antibiotic era.
58
189241
5062
我的曾伯父在前抗生素时代
最后的日子中去世的
最后的日子中去世的
03:26
We stand today on the threshold
of the post-antibiotic era,
of the post-antibiotic era,
59
194303
5154
我们现在已经能看到后抗生素时代的到来
03:31
in the earliest days of a time
when simple infections
when simple infections
60
199457
3762
感染会像从前一样致命，
03:35
such as the one Joe had
will kill people once again.
will kill people once again.
61
203219
4709
杀死乔（曾伯父）的致命感染会卷土重来
03:40
In fact, they already are.
62
208884
3131
其实，
这些感染已经夺取了很多人的性命了
这些感染已经夺取了很多人的性命了
03:44
People are dying of infections again
because of a phenomenon
because of a phenomenon
63
212785
2833
人们再次死于感染因为有一种现象
03:47
called antibiotic resistance.
64
215618
2343
叫做抗生素抗药性
03:50
Briefly, it works like this.
65
218381
1738
简单的来说，它的原理是这样的
03:52
Bacteria compete against each other
for resources, for food,
for resources, for food,
66
220119
4972
细菌为了资源和食物相互竞争，
03:57
by manufacturing lethal compounds
that they direct against each other.
that they direct against each other.
67
225091
4667
有的细菌会针对性地制造
致命的化合物攻击对方
致命的化合物攻击对方
04:01
Other bacteria, to protect themselves,
68
229758
2345
其它的细菌则用化合物保护自己，
04:04
evolve defenses against
that chemical attack.
that chemical attack.
69
232103
3251
发展防御系统对抗这些化学攻击
04:07
When we first made antibiotics,
70
235354
2322
我们最初发明抗生素时，
04:09
we took those compounds into the lab
and made our own versions of them,
and made our own versions of them,
71
237676
4202
我们在实验室中创造了
我们自己版本的化合物
我们自己版本的化合物
04:13
and bacteria responded to our attack
the way they always had.
the way they always had.
72
241878
4458
细菌像往常一样对我们的攻击作出了响应
04:19
Here is what happened next:
73
247674
2224
接下来是这样的：
04:22
Penicillin was distributed in 1943,
74
250098
3390
青霉素是在1943年发布的，
04:25
and widespread penicillin resistance
arrived by 1945.
arrived by 1945.
75
253488
5131
而广泛的青霉素耐药性在1945年就到来了
04:30
Vancomycin arrived in 1972,
76
258619
2949
万古霉素出现在1972年，
04:33
vancomycin resistance in 1988.
77
261568
3100
万古霉素耐药性就在1988年
04:37
Imipenem in 1985,
78
265028
2122
亚胺培南于1985年，
04:39
and resistance to in 1998.
79
267150
2772
抗药性在1998年又出现了
04:42
Daptomycin, one of
the most recent drugs, in 2003,
the most recent drugs, in 2003,
80
270192
3668
2003年的达托霉素是最新的药物之一，
04:45
and resistance to it
just a year later in 2004.
just a year later in 2004.
81
273860
4365
抗药性在2004年就紧跟而至
04:50
For 70 years, we played
a game of leapfrog --
a game of leapfrog --
82
278575
3760
在这70年中，
我们像是在做一个蛙跳的游戏 --
我们像是在做一个蛙跳的游戏 --
04:54
our drug and their resistance,
83
282335
2926
一种药物，一种抗药性，
04:57
and then another drug,
and then resistance again --
and then resistance again --
84
285261
3645
接下来又一种药物，又一个抗药性 --
05:00
and now the game is ending.
85
288906
2311
现在这个游戏结束了
05:03
Bacteria develop resistance so quickly
that pharmaceutical companies
that pharmaceutical companies
86
291437
4040
细菌的抵抗力极快，
以至于制药公司
以至于制药公司
05:07
have decided making antibiotics
is not in their best interest,
is not in their best interest,
87
295477
4365
认为生产抗生素不是他们的最佳利益，
05:11
so there are infections
moving across the world
moving across the world
88
299842
2810
所以现在各种感染风靡全球，
05:14
for which, out of the more
than 100 antibiotics
than 100 antibiotics
89
302652
3459
市场上可购买到的100多种
05:18
available on the market,
90
306111
2229
抗生素中，
05:20
two drugs might work with side effects,
91
308340
3414
可能只有两种药物会管用，
并带有副作用
并带有副作用
05:23
or one drug,
92
311754
2484
或者一个药，
05:26
or none.
93
314238
1408
甚至没有
05:28
This is what that looks like.
94
316096
1572
看上去就是这个样子的
05:30
In 2000, the Centers for Disease
Control and Prevention, the CDC,

95
318278
4180
在2000年，

05:36
in a hospital in North Carolina
97
324501
2252
在一家位于北卡罗来纳的医院里
05:38
of an infection resistant
to all but two drugs.
to all but two drugs.
98
326753
3733
除了两种药外，对其它药物都有抗药性
05:42
Today, that infection, known as KPC,
99
330886
4319
现在，这种感染被称为KPC，
05:47
has spread to every state but three,
100
335205
2600
除了3个州外，已经传播到了美国各地，
05:49
and to South America, Europe
101
337805
2345
还有南美，欧洲
05:52
and the Middle East.
102
340150
2207
和中东地区
05:54
In 2008, doctors in Sweden
103
342867
2322
在2008年，瑞典医生
05:57
diagnosed a man from India
with a different infection
with a different infection
104
345189
2786
确诊一名来自印度的男子患有的感染
05:59
resistant to all but one drug that time.
105
347975
3715
只对一种药没有抗药性
06:03
The gene that creates that resistance,
106
351690
2229
创造这种抗药性的基因
06:05
known as NDM, has now spread
from India into China, Asia, Africa,
from India into China, Asia, Africa,
107
353919
6525
叫做NDM，现在已经从印度传播到
中国，亚洲，非洲，
中国，亚洲，非洲，
06:12
Europe and Canada, and the United States.
108
360444
4365
欧洲和加拿大，还有美国
06:17
It would be natural to hope
109
365129
2559
我们真心希望
06:19
that these infections
are extraordinary cases,
are extraordinary cases,
110
367688
3599
这些感染病例只是罕见情况，
06:23
but in fact,
111
371287
1858
但是其实，
06:25
in the United States and Europe,
112
373145
2461
在美国和欧洲，
06:27
50,000 people a year
113
375606
2716
每年都有50,000人
06:30
die of infections which no drugs can help.

06:50
That is a lot of deaths,
118
398291
4364
这个数字巨大，
06:54
and yet, the chances are good
that you don't feel at risk,
that you don't feel at risk,
119
402655
3112
然而这个比例还是很小，
所以我们感觉不到风险，

感觉他们离我们很远，
07:09
in situations we can't identify with.
124

is that antibiotics support

抗生素支撑着几乎所有的现代生活
07:23
If we lost antibiotics,

如果我们失去了抗生素，
07:25
here's what else we'd lose:
128

接下来，我们可能会失去手术
08:05
Many operations are preceded

473869
2322
很多手术的进行
08:08
by prophylactic doses of antibiotics.
140
476191

需要预防性剂量的抗生素
08:11
Without that protection,

如果没有这个措施，

we'd lose the ability to open

we live our everyday lives.

153
519333

我们失去了生活的信心
08:56
If you knew that any injury
could kill you,

“滥用青霉素的无知的人

is morally responsible
for the death of a man

导致那些人为此丧命。“
12:36
He added, "I hope this evil
can be averted."

避免这个厄运。“
12:40
Can we avert it?
211
748986
2856
我们能避免它吗？
12:43
There are companies working
on novel antibiotics,

212
751842

12:47
things the superbugs
have never seen before.

213

12:51
We need those new drugs badly,
214
759086
2717
我们十分迫切地需要这些药物，
12:53
and we need incentives:
215
761803
2252
我们也需要一些奖励：
12:56
discovery grants, extended patents,
216
764055
2531
研发补助，延长专利，
12:58
prizes, to lure other companies
into making antibiotics again.
into making antibiotics again.
217
766586
6757
奖金等等，
去吸引其它公司再次制造去抗生素
去吸引其它公司再次制造去抗生素
13:05
But that probably won't be enough.
218
773343
2366
但是这还不够
13:08
Here's why: Evolution always wins.
219

这就是原因：大自然的进化总会赢
13:12
Bacteria birth a new generation

We changed social norms.

我们改变了社会规范

We could change social norms

我们也可以改变抗生素使用的规范

I know that the scale

我知道抗生素耐药性的规模

不要执意为孩子的耳部感染开处方，
16:02
before we're sure what caused it.
265
950564
1898
而是先查明起因
16:05
We could ask every restaurant,
266
953678
3367
我们可以询问每一家餐厅，
16:09
every supermarket,
267
957045
1811
每一家超市
16:10
where their meat comes from.
268
958856
1620
它们的肉制品是从哪里来的
16:12
We could promise each other
269
960806
1834
我们可以做承诺
16:14
never again to buy chicken
or shrimp or fruit

16:18
raised with routine antibiotic use,

2884
鸡，虾或水果，
16:21
and if we did those things,
272
969629
2694
若果我们能做到这些，
16:24
we could slow down the arrival
of the post-antibiotic world.
of the post-antibiotic world.
273
972323
4492
我们可以减缓后抗生素时代的到来
16:29
But we have to do it soon.
274
977547
4133
但是我们要马上开始行动
16:33
Penicillin began
the antibiotic era in 1943.
the antibiotic era in 1943.
275
981680

青霉素在1943年开启了抗生素时代

In just 70 years, we walked ourselves

16:44
We won't get 70 years

我们没有70年的时间
16:46
to find our way back out again.

ABOUT THE SPEAKER
Maryn McKenna - Public health journalistMaryn McKenna recounts the often terrifying stories behind emerging drug-resistant diseases that medical science is barely keeping at bay.
Why you should listen
Maryn McKenna’s harrowing stories of hunting down anthrax with the CDC and her chronicle of antibiotic-resistant staph infections in Superbug earned her the nickname “scary disease girl” among her colleagues.
But her investigations into public health don’t stop there: she blogs and writes on the history of epidemics and the public health challenges posed by factory farming. For her forthcoming book, McKenna is researching the symbiotic history of food production and antibiotics, and how their use impacts our lives, societies and the potential for illness.
