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，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，发展出了同名的抗甲氧西林耐药性。

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

而一项新研究发还是甲氧西林（从青霉素提取的一种抗生素）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，我偶然发了上世纪60年代一份旧研究，显示体内有种特殊真菌能产生与甲氧西林非常相似的类似青霉素的抗生素。”

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，这项研究展示了体内的一种特定真菌能够产生一种类似青霉素的抗生素，这种抗生素与甲氧西林非常相似。
