课文内容 词汇: medicine 药物

If you live in England and have a mild infection, don't ask your GP to recommend antibiotics. He'll probably say 'no' and give you something else. This is part of an initiative to put a stop to harmful infections becoming resistant to these drugs.

Recent figures from the NHS have shown that the number of prescriptions for all types of antibiotics were down by 7.3% on the previous year to about 34 million in 2017 and 2016, which is considered a success by the authorities.

Peter Taylor, Professor of Microbiology, UCL School of Pharmacy, says that antibiotics are probably "the safest and most effective drugs ever produced, but they have an Achilles heel - every time we use an antibiotic it alters the levels of bacteria out there in the environment and engenders resistance in a way that is very similar to Darwinian natural selection".

The power of these substances was discovered by Alexander Fleming in 1928 almost by chance. The Scottish bacteriologist returned to his laboratory after a holiday to find a bacteria-free circle around a growth of mould on a Petri dish. It gave us our first antibiotic: penicillin.
