But that's not really quite enough
但是這些信息還不夠
for me to know exactly what this bug is,
對我來說 必須清楚地知道這是什么
so we grow it on plates like this,
所以我要在培養皿里培養它
and each of these dots
每個像這樣的菌落里
has about a half-billion organisms in it.
有將近五億個有機體
These discs here have got antibiotics in them
這些小圓盤里含有抗生素
which leak out into the agar,
并會釋放到瓊脂中
and if you look at that one there,
如果你看那里
you can see there's a very, very,
你會發現這個很大一塊區域
very, large zone of clearing
什么都沒有
and that's because that antibiotic
這是因為
is killing that organism,
這種抗生素殺死了有機體
but if you look at all the others,
但若再觀察其他的
there's no effect at all.
根本就沒有效果
So this plate is telling us
所以這個培養皿告訴我們
that my patient has got a highly resistant organism,
病人體內生有高度耐藥性有機體
and this explains why
這就解釋了
she's not doing quite as well as she should,
為什么她沒有像預期的那樣好起來
so resistant to one, two, three, four, five antibiotics,
對這五種抗生素都有耐藥性
sensitive to only one.
只對一種敏感
Our resistance to antibiotics
我們對于抗生素的耐藥性
is a problem that's only getting worse.
是一個日趨嚴重的問題
