Foodborne infections often occur through the contamination of equipment, food-prep tools, and unsanitary surfaces. A recent report from the Centers for Disease Control and Prevention (CDC) reminds us that breast pump parts are part of the food-delivery chain — and they can become contaminated too.
Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.

Four million Americans misused prescription opioid painkillers in 2014. Those who do are 40 times more likely to inject heroin or other drugs than other people. Now, the Centers for Disease Control and Prevention (CDC) are blaming that misuse for a 12-fold increase in endocarditis, an infection of the heart valves.
Not all bacteria in the eyes cause infection. A group of researchers from the National Eye Institue has shown that not only is there a population of bacteria on the eyes that reside there but they perform an important function. They help activate the immune system to get rid of bad, potentially infection-causing — pathogenic — bacteria there.

Montezuma's revenge, the runs, the trots, or just diarrhea — everyone gets it sooner or later. What exactly is diarrhea good for, if anything?
How can bacteria that lives in the throat of 10%–35% of people—without causing an infection—cause life-threatening meningitis and sepsis in others?
Most females have had at least one urinary tract infection in their lifetimes. Recurrent UTIs are particularly problematic in young, sexually active women, where about 80% of the infections are caused by the bacteria Escherichia coli, better known as E. coli.
Humanity is standing on an infection precipice. As antibacterial resistant grows, we're running out of options, and a recent scary case of total antibiotic resistance is a frighting view of our potential future. In the end, it was septic shock that took the life of a 70-year old woman with an incurable infection. One of few such cases in the US, her death could nonetheless be the shape of things to come.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.

Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
