Bacteria

A new long-term study has found high levels of antibiotic-resistant bacteria in wild dolphins, with rates growing over the last decade.

Deadly, drug-resistant forms of K. pneumoniae bacteria are spreading. Thankfully a new vaccine has shown promise in tests on mice.

An intriguing study suggests beneficial blood pressure reductions following exercise are kickstarted by molecules released by bacteria in the mouth.

Researchers at Imperial College London have found that a high-priority superbug resists drugs by closing its pores.

Researchers from the University of Virginia may have found a way to prevent infections. The team has uncovered how pathogenic E. coli senses its environment to stay stealthy until it reaches the right spot to kickstart an infection.

The results from a Phase 1 trial into the safety of a landmark chlamydia vaccine have just been published demonstrating promising signs the treatment is safe, and potentially effective in preventing the most common bacterial sexually transmitted infection in the world.

Slapping on a Band-Aid is the easiest way to help a cut on your skin heal, but things aren’t so simple for internal wounds. Now, researchers from Harvard have developed spray-on hydrogels, produced by bacteria, that can help heal these internal wounds.

Antibiotics aren’t picky, blasting good and bad bacteria alike and messing up the delicate balance of the gut microbiome. But now researchers have developed a more targeted approach, with drugs that are able to zero in on specific species of bacteria.

​The most numerous of organisms on Earth, bacteriophages are viruses that infect and kill bacteria. Now, scientists have grown enough of them to create a self-healing hydrogel that's made almost entirely of the things. It could have important applications in medicine, and in other fields.

Bacteria are rapidly developing resistance to our best drugs, hurtling us towards a future where antibiotics simply don’t work anymore. Now researchers have uncovered a potentially exploitable chink in the armor of a particularly troublesome group of bacteria.

Graphene is incredibly thin, flexible, strong and electrically conductive, but it’s tricky to manufacture on large scales. Now researchers at the University of Rochester have recruited bacteria to make the stuff, which is cheaper and faster than current methods and doesn’t require harsh chemicals.

After studying proteins that are key to metabolism in modern cells, researchers reverse engineered a simplified protein that may have been responsible for kickstarting the process in ancient times. And to prove the idea, they then implanted it into living bacteria and found that it works just fine.
