[揽瓜阁精读] 272. DNA抗体

ANING1224

P1:帮助细菌对药物产生抗药性的DNA可能越来越多成为水中的污染物。
P2:这种DNA的传播可能会加剧在传染性微生物中已经日益严重的耐药性问题
P3:虽然抗生素会杀死许多没有耐药性的西晋，但它们也会促进耐药微生物的传播。
P4-P5普鲁登关于帮助细菌产生耐药性的研究
P6四环素和磺胺这两个产生耐药的基因都与城市和农场活动有关
P7:研究人员在他们调查的所有水域中都发现了耐药性基因的存在
P8：DNA可能存在死亡或活着的细胞内，但也可能漂浮在细胞外的水中
P9：研究人员还将继续探索，以帮助其破坏DNA

272. DNA抗体


P1 - DNA may increasingly be appearing as a pollutant in the water.
P2 - The DNA was found even in treated drinking water.
P3 - The spread of this DNA could exacerbate the growing problem of drug resistance among potentially infectious microbes.
P4 - Antibiotics also prompt the spread of microbes that are resistant. The over-prescription helps these resistantinfections emerge. Humans and animals excret the antibiotics into the environment.
P5 - Prudent looked for the presence of genes that help confer drug resistance to the germs in the first place.
P6 - Pruden: the spread of antibiotic-resistance genes in the environment is undesirable.
P7 - Pruden focused on genes conferring resistance against two antibiotics, T and S, which are linked to urban and farm activity. They investigated a range of waters.
P8 - The levels of antibiotic-resistancec genes were hundreds to thousands of times higher in waters directly impacted by urban or farm activity than in relatively pristine waters. Still, the presence is discovered in all waters.
P9 - Pruden: Wastewater treatment systems are not designed to treat antibiotic-resistance genes. The chlorinating treatment inactivates bacteria but does not destroy DNA.
P10 - The researchers will further investigate what other antibioti-resistance genes are present in the environment and explore ways to modify wastewater treatment plants to help them destroy DNA.
