Small amounts of silver nanoparticles combined with a common antibiotic block the growth of resistant bacteria, new research shows.

A new blood test is 90% accurate in figuring out if an infection is bacterial or viral. It could help cut antibiotic overuse globally.

Research shows that COVID disrupts a healthy balance between good and bad microbes in the gut, especially with antibiotic treatment.

Borrelia burgdorferi, the bacteria that causes Lyme disease, uses tenacious trial-and-error movements to worm their way in and infect us.

"By using a targeted delivery system, we can actually reduce the dose of the antibiotic and still effectively kill the pathogen."

A new drug combination appears to be more effective against complicated urinary tract infections, especially those that are drug-resistant.

"The practical implication is simple: Avoid antibiotic use in young children whenever you can..."

The co-development of three systems—the gut microbiome, respiratory system, and immune system—is correlated with a baby's respiratory health, research shows.

"Sometimes parents think that the worst that could happen is that the antibiotic just won't help their child. But antibiotics are not harmless..."

Nanoparticle drugs, or nanobiotics, could one day treat infections that antibiotics can't. Machine learning gets this vision a step closer.
