Hand washing is an effective way to help prevent the spread of bacteria.
Millions of bacteria live on our skin without making us sick. It's when they manage to get through that they can be dangerous – particularly if they're resistant to antibiotics.
Every surface of our body – inside and out – is covered in microorganisms: bacteria, viruses, fungi and many other microscopic life forms.
Just because you don't have the flu doesn't mean that your aren't teeming with viruses inside and out. But what are all these viruses doing, if they aren't making you sick?
Put down that bleach.

Cancer immunotherapies are considered as revolutionary. But many cancer patients don't respond to them. In a new clinical trial, researchers are testing whether gut microbes are the key to remission.
Clinical trials involving probiotics are failing to report on the safety and harms of these treatments.
Gut microbe composition is fairly similar across a range of diseases.
Certain gut microbes have been associated with certain diseases, but a new study finds that the pattern of microbes is consistent across a range of diseases.

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.
By the time they turn one, half of Australian babies have had a course of antibiotics.
There may be additional long-term health harms from antibiotic exposure in early life and before birth, including an increased risk of infection, obesity and asthma.
Manipulating environmental exposures to optimize a healthy microbiome may hold the promise of preventing chronic inflammatory diseases, such as Crohn’s disease and ulcerative colitis.
Halting the rapid rise in inflammatory bowel disease will require a proactive approach to medicine, and a focus on the gut.
