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

因此，如果真想对 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.

而项新研究发现刺猬还是甲氧西林（从青霉素提种抗生素）耐药性来源。

" … 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代份旧研究，显示刺猬体内有种特殊真菌能产生与甲氧西林非常相似类似青霉素抗生素。”

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，我偶然找到了项20世纪60代旧研究，这项研究展示了刺猬体内种特定真菌能够产生种类似青霉素抗生素，这种抗生素与甲氧西林非常相似。
