Antibiotic

A recent study has shown that nanoplastics – plastic particles smaller than 0.001 millimeters – affect the body's ability to absorb antibiotics, and may even lead to the growth of antibiotic-resistant bacteria.

A. baumannii bacteria is a nasty antibiotic-resistant bug that thrives in hospitals, where it takes advantage of weakened immune systems. Researchers have now found the bacteria's secret weapon and have ideas on how to use it for good.

Science's war against the super-small and, sometimes, super-deadly bacteria that have evolved to resist destruction by antibiotics may have just enlisted new, unlikely allies: invertebrate creatures living in the frigid depths of the Arctic Ocean.

Researchers have combined the bacteria-killing actions of two classes of antibiotics into one, demonstrating that their new dual-action antibiotic could make bacterial resistance (almost) an impossibility.

Antibiotics kill disease-causing bacteria as well as the beneficial ones living in our gut, disturbing the health-maintaining microbiome. A new antibiotic specifically targets hard-to-kill bacteria while leaving our good gut bacteria alone, according to a new study.

US doctors haven’t been following the rules when it comes to prescribing antibiotics, according to new research. Despite the rise in antibiotic resistance, between 2017 and 2021 more than a quarter of antibiotics prescribed were for conditions they’re ineffective against.

A mussel protein could one day keep infections from occurring at the site of bone implants such as artificial hips. And while the protein does kill the microbes, it should still limit the development of antibiotic-resistant "superbacteria."

Bacteria often go dormant to avoid being wiped out by antibiotics, which makes treatment difficult. Now scientists have discovered a virus that can attack these sleeping bugs, clearing out infections effectively when paired with drugs.

It has been known for some time now that chemicals produced by certain ants have antibiotic properties. For the first time, however, one species of ant has been observed actually using those chemicals to treat infected wounds on others of its kind.

Antibiotic-resistant bacteria are poised to become a global health concern. In the race to develop new weapons, scientists have created a new family of antibacterial polymers that can kill 'superbugs' in a way they can't evolve resistance to.

The human body's microbe makeup is increasingly linked to the onset of many diseases, with a lot of the focus on the gut. A new study, however, has found that changes in the bug populations in not just the gut but in salivary and urinary microbiomes are linked to kidney stones forming.

A study has found that using a digital support algorithm to guide treatment by healthcare providers significantly reduced the number of antibiotic prescriptions given to acutely sick children, without affecting treatment success or causing harm.
