Grazing is expected to exert a substantial influence on antibiotic resistance genes (ARGs) in grassland ecosystems. However, the precise effects of grazing on the composition of ARGs in grassland soils remain unclear. This is especially the case for grassland soils subject to long-term grazing. ...

These discoveries were tempered in all cases by the emergence of resistant microbes. This history has been interpreted to mean that antibiotic resistance in pathogenic bacteria is a modern phenomenon; this view is reinforced by the fact that collections of microbes that predate the antibiotic era ...
which led to the production of the penicillinase-resistant penicillins (methicillin, oxacillin, nafcillin, cloxacillin, and dicloxacillin). The use of several of these agents, however, has been severely limited by resistance; methicillin is no longer used, because of the emergence ofmethicillin-resis...
What is antibiotic resistance? Antibiotic resistance happens when an antibiotic loses its ability to effectively control or kill bacteria. The bacteria become "resistant" and continue to grow because the antibiotic being administered has no ability to kill them. The World Health Organization, the U....
Antibiotic resistance is an increasing health problem, but new research suggests it is not only caused by the overuse of antibiotics. It's also caused by pollution. Using a process known asgenomic analysis, University of Georgia scientists found a strong correlation betweenantibiotic resistanceand hea...
Antibiotic-resistant bacteria are a growing problem in health care globally. To prevent further development of resistance, it is important to understand where and how antibiotic resistance in bacteria arises. New research from Uppsala University shows th
In particular, antibiotic resistance is caused by complex mechanisms relating to emergence and transmission. The paucity of knowledge about these mechanistic processes is primarily one of the reasons very little has been achieved for effective prevention and control (Santajit and Indrawattana, 2016; ...
Antibiotic resistanceis a further example of a similar problem. Bacteria are not subject to immigration controls, and the ability of the organisms to exchange genetic material, conferring antibiotic resistance, between individuals and in different parts of the world where there are differing medical pra...
