Cholera is a devastating disease for millions worldwide, primarily in developing countries, and the dominant type of cholera today is naturally resistant to one type of antibiotic usually used as a treatment of last resort.
Antibiotic resistance happens when bacteria evolve mechanisms to withstand the drugs which are used to treat infections.
In recent years, scientists, clinicians and pharmaceutical companies have struggled to find new antibiotics or alternative strategies against multi-drug resistant bacteria that represent a serious public health problem. In ...
Twenty-five years ago, waterhemp was virtually unknown to Illinois farmers. Today, the broadleaf weed blankets corn and soybean fields across the state and the Midwest, causing yield losses from 40 to 70 percent.
Rice University scientists are developing strategies to keep germs from evolving resistance to antibiotics by heading them off at the pass.
Researchers from The University of Western Australia's Institute of Agriculture are conducting the world's largest chickpea experiment on drought resistance.
To understand genetic mechanisms underlying insecticide resistance, scientists employed fruit flies and caffeine, a stimulant surrogate for xenobiotics in lab studies on resistance.
The system that allows the sharing of genetic material between bacteria – and therefore the spread of antibiotic resistance – has been uncovered by a team of scientists at Birkbeck, University of London and UCL.
(Phys.org) —Molecular biologists at the University of Wyoming have found a molecular mechanism that allows myxobacteria to recognize related strains that lead to the transient fusion of their outer membranes to exchange ...
