Antibiotic resistancegenes generally have little effect on the host cell's overall fitness. For example, many of these genes actually destroy theantibioticand do not alter the target site. Further, the expression of some resistance genes is actually induced by the antibiotic, so there is even les...
Hundreds of tonnes of genetically modified corn seeds sold to farmers by mistake over the past four years contained a gene for antibiotic resistance, Nature has learned. The release of such genes into the environment is sometimes considered inadvisable, as there is a small chance that they could...
【1.2】抗生素抗性基因(Antibiotic Resistance Genes) 抗生素耐药性是分子生物学中广泛使用的工具,但科学家们很少停下来思考它让我们的生活变得多么轻松。质粒转化到大肠杆菌中是一个相当低效的过程——平均只有 10,000 个细胞中有 1 个!如果没有快速确定哪些细胞成功接收到正确质粒的方法,科学家们将花费数小时到数天...
Antibiotics are widely used in animal husbandry, and various types of antibiotic resistance genes (ARGs) are frequently detected in livestock waste around the world. Conventional livestock waste treatment processes do not completely remove ARGs, resulting in their release to soil and water environments....
Antibiotic-resistance genes that determine the production of enzymes which modify (detoxify) the antibiotics have been detected in antibiotic-producing organisms. It has been suggested that the producing strains provided the source of antibiotic-resistance genes that were then 'picked-up' by ...
They are widespread and can include resistance to many different antibacterials, to genes involved in bacterial–host interactions as well as to other “accessory” genes, which are important to the host under some conditions of growth. Classical examples are tetracycline resistance transposon, Tn10 ...

Antibiotic resistance has become a widely concerned issue due to the huge risk on the ecological environment and human health. China has the highest production and consumption of antibiotics than other countries. Thus, antibiotic resistance genes (ARGs) have been detected in various environmental settin...
The emergence, prevalence, and differences in resistance genes in the intestines of yaks, beef, and dairy cattle may be caused by the selective pressure of different feeding patterns, where yaks were raised without antibiotics for growth promotion. In addition, the abundance of ARGs in yak was ...
