So if we really want to show MRSA no mercy, we should keep the methicillin to a minimum.

因此，如果真的想对 MRSA 毫不留情，我们应该让甲氧西林保持最低量。

And you'd assume that it developed its namesake resistance to methicilli...by being exposed to methicillin.

你可能会认为它接触甲氧西林，发展出了同名的甲氧西林耐药性。

Now, a new study says that they are also the origin of resistance to methicillin, an antibiotic derived from penicillin.

而一项新研究发现刺猬还是甲氧西林（从青霉提取的一种）耐药性的来源。

" … where I came across an old study from the 1960s which showed that a particular fungus in hedgehogs is able to produce a penicillin-like antibiotic that is very similar to methicillin."

“在那里，我偶然发现了上世纪60年代一份旧研究，显示刺猬体内有种特殊真菌能产与甲氧西林非常相似的类似青霉的。”

To find out, Larsen went to the library… … where I came across an old study from the 1960s which showed that a particular fungus in hedgehogs is able to produce a penicillin-like antibiotic that is very similar to methicillin.

为了找出答案，拉森去了图书馆… 在那里，我偶然找到了一项20世纪60年代的旧研究，这项研究展示了刺猬体内的一种特定真菌能够产一种类似青霉的，这种与甲氧西林非常相似。
