The evolutionary history of antibiotic resistance suggests it may be impossible to develop resistance-proof antibiotics so what are our other options?
While some ancient therapies proved effective enough that they are still used in some form today, on the whole they just aren't as good as modern antimicrobials at treating infections.
Yo-yoing between eating well during the week and bingeing on junk food over the weekend is likely to be just as bad for your gut health as a consistent diet of junk.
Doctors often tell patients to take a “course” of antibiotics, because a partially treated infection may result in relapse with antibiotic-resistant bacteria. But where this advice come from?
Bacteria are becoming increasingly resistant to antibiotics and we are approaching a time when there could be many bacteria resistant to all the antibiotics we have. So how do we stop over-using them?
Researchers in China have found strains of E.coli that are resistant colistin, the antibiotic of last resort.
More than 700,000 people die each year from antibiotic-resistant infections. The World Health Organisation is trying to end the age of ignorance to protect this global common good.
Antibiotics are used extensively in Africa because of the continent's high disease burden. This also means that resistance is high. Steps are being taken to raise awareness and encourage prudent use.
Would you freeze your poo for a rainy day of ill health?
Bacteria become problematic when an infection occurs and antibiotics that would have treated the infection are no longer effective.
Human activities have altered whole ecosystems with declines in species diversity, extinctions and the introduction of weeds and pests. But it's not just the outside world we're harming.
When we think of antibiotic overuse, we don't generally think of allergies. Research is beginning to suggest that maybe we should.
A narrow focus on bacteria that produces high levels of toxin may have misled researchers in the pursuit to understand superbugs.
Antibiotics can prevent serious harm and stop infections becoming fatal. But they won't kill common cold and flu viruses, and careless overprescribing by doctors can do more harm than good.
We used to think that antibiotic resistance came at a cost for bacteria, making them weaker. It turns out that for some bacteria, resistance can make them stronger and more virulent.
Antibiotic resistance is pressing issue in medicine but the extensive use of antibiotics in farming is part of the problem.
Bacteria qualify as "superbugs" when there are no or few remaining effective antibiotics to kill them.
Superbugs are back in the news – and everybody loves a good germ panic story.
Proposals for a new way to fund antibiotic research and development are just one piece of the puzzle in the fight against drug-resistance.
Advice that you have to finish the whole course of antibiotics reflects long-standing convention or the drug manufacturer’s decision during an initial trial, rather than scientific evidence.
