Antibiotics, before they became used as drugs, were natural products. A new finding provides the first direct【C1】______that antibiotic resistance is a widespread natural phenomenon that【C2】______the modern medical use of antibiotics. Experts had long predicted this on theoretical【C3】______, but they say the new finding【C4】______the need to use antibiotics sparingly, 【C5】______that the genes for antibiotic resistance are very common and can easily be【C6】______by antibiotics. "The fact that the genes for resistance are so ancient and widespread means there is no easy【C7】______to the problem of resistance — we will never invent a super-antibiotic that【C8】______everything up," said Martin J.

After millions of years of chemical【C11】______, two classes of sophisticated genes have【C12】______, those that make antibiotics and those that provide resistance to antibiotics. "Antibiotic resistance is part of the natural ecology of the planet, and this finding is a【C13】______note about how we use these things," Dr. Wright said.

"What had been missed in the 1960s and 1970s was the【C20】______with which resistance could appear," he said. "Bacteria share these genes like baseball cards with each other. "[308 words]
