研究:青蛙皮肤可对抗超级细菌

　　Scientists have long known that the skin of frogs contains plenty of powerful germ-fighting substances because of the hostileenvironments they exist in.

　　科学家很久以前就知道，由于生存环境恶劣，青蛙的皮肤中含有大量能够对抗微生物的物质。

　　But the substances are also often poisonous to humans.

　　但对人来说，这些物质同样含有剧毒。

　　Now a team at the United Arab Emirates University have worked out a way of modifying the chemicals to remove their harmful side-effects.

　　现在，阿联酋大学的一个研究小组找到了一种办法，对这些化学物质进行处理，消除有害的副作用。

　　They have already identified 100 new antibioticsincluding one that could fight the superbug.

　　他们已经发现了100种新型抗生素，其中包括一种能够对抗超级细菌的抗生素。

　　Frog skin is an excellent potential source of such antibiotic agents," said Dr Michael Conlon, a biochemist at the university in Abu Dhabi.

　　阿布扎比大学生物化学家迈克尔·康伦博士表示，青蛙皮肤是该抗生素一个极佳的潜在来源。

　　“They`ve been around 300 million years, so they`ve had plenty of time to learn how to defend themselves against disease-causing microbes in the environment.”

　　“它们已存在约3亿年，因此它们有足够的时间来学习如何保护自己免受环境中致病微生物的伤害。”

　　"Their own environment includes polluted waterways where strong defences against pathogens are a must."

　　“它们生存的环境就包括受到污染的水域，在这种地方，它们必须具有对病原体的强大防御能力。”
