New technology could help doctors identify the right antibiotic for their patient in double-quick time.
These are viruses called bacteriophages that infect only bacterial cells.
Bacteria are becoming resistant to even the most powerful antibiotics. These expensive, hard-to-treat infections are prompting physicians to reassess using viruses to destroy bacteria.
New research suggests that raising public awareness about antimicrobial resistance may have unintended consequences.
Whooping cough is making a comeback. Here's how to identify it, and why vaccination is a way to protect babies.
Farm workers are susceptible to Q fever.
Q fever explained.
Not many people realise ants can make their own medicine.
Hydrogen peroxide is a chemical that can kill germs. It is found in two things many ants love to eat: nectar and honey dew.
Farmers are closest to the land and their livestock, and have everything to lose by not taking care of it.
Antibiotics are only useful for treating infections caused by bacteria, not viruses or fungi.
It's hard to predict how long it will take to feel better after you start taking antibiotics. But if you start feeling worse one to two days after starting the therapy, you must see your doctor.
And don’t infect everyone else in the office either.
The overuse of antibiotics puts vulnerable patients and society at risk.
We still don’t know what types of bacteria are truly beneficial.
Probiotics might avert a case of diarrhoea, or they could mean your gut takes longer to return to normal.
There already exist some promising new antibiotic therapies, and more are in the pipeline. However, our economic model prevents researchers from moving them out onto the market.
The end of effective antibiotics will be frightening. Life expectancy will fall dramatically and people of all ages will die from illnesses that we are used to treating with $10 worth of pills.
Our view of this essential dimension of earth’s biome has been shaped by the manufacturers of cleaning products.
Alexander Fleming's work has helped countless people over the last nine decades.

It's not a matter of if, but when, the next deadly pandemic will strike. Will the world be ready?
The truth about cats and dogs.
Farm animals are the subject of WHO initiatives around antibiotics, but domestic pets could actually be a bigger risk.
Antibiotic-resistant bacteria inside a biofilm.
Triclosan, an ingredient in soap and many household cleansers, has gained a bad reputation. A recent study looking for a way to boost an antibiotic, however, found that tricloscan did a great job.
Clostridium difficile bacteria causes diarrhea and inflammation of the colon.

A new type of antibiotic uses DNA to fight a common deadly microbe, Clostridium difficile. These new drugs are inexpensive and adaptable and can be modified to target any bacterium, lowering the chance of drug resistance.
Getting rid of this scourge is nothing to be sneezed at.
Cattle that are grass-fed, antibiotic- and growth hormone-free gather at a farm in Oregon in 2015. There’s a debate over whether antibiotic use in livestock makes germs more resistant to the drugs, and results in infections being passed on to humans who consume the meat.

The use of antibiotics in raising livestock is complex. We could be moving towards a less-than-ideal result due to poor understanding, over-simplistic messaging and a rush for competitive advantage.
Bacteria in the dish on the left are sensitive to antibiotics in the paper discs. The ones on the right are resistant to four of the seven antibiotics.

Antibiotic-munching microbes may prove useful for mopping up contaminated water supplies and land.
