Antibiotic-resistant bacteria

Scientists have uncovered a promising new pathway in the development of tuberculosis drugs, describing what they call a newly-discovered “keyhole” that can be targeted to starve tuberculosis-causing bacteria of the sustenance they need to survive.

The growing problem of antibiotic resistance isn’t slowing down, which could soon render our best drugs useless against infection. Now, an existing rheumatoid arthritis drug could be repurposed to cancel bacteria’s resistance to antibiotics.

Fat is best known for being an energy storage system, but it may also play a previously-unknown role in defense against infection. Scientists from the Universities of Queensland and Barcelona have found that cells can use fats to fight off bacteria.

Antibiotic-resistant bacteria are poised to become a huge health problem, and we desperately need new treatments. Now, researchers have engineered new antimicrobial molecules from wasp venom, which have shown promise in tests in mice.

In a move that could lead to new innovations in antibiotic production, the genome of a freeze-dried sample of Sir Alexander Fleming's original mold that led to his discovery of penicillin has been sequenced for the first time.

The usefulness of antibiotics is beginning to unravel, with potentially devastating results. In the hunt for new drugs, researchers have now investigated how an antivitamin of Vitamin B1 could be a promising new weapon against these “superbugs.”

Australian scientists have discovered a previously unknown protective mechanism bacteria use to kill immune cells, opening up potential research pathways that could help doctors fight antibiotic-resistant superbugs.

Bacteria are fast developing resistance to antibiotics, but we may soon have a new weapon to fight back. Bacteriophages are viruses that prey on bacteria, and now scientists have used them to treat Golden Staph infections in diabetic foot ulcers.

A Medieval medical book hold the key to new ways to combat antibiotic-resistant bacteria. Scientists have found that a medical recipe from the ancient Bald's Leechbook is effective against five strains of bacteria that cause biofilm infections.

Antibiotic-resistant bacteria are emerging as a serious public health threat. Now, researchers have developed a system using nanoparticles wrapped in graphene oxide to kill both the superbugs and their free-floating resistance genes in wastewater.

Scientists at the University of Exeter have developed a promising technique that could help slow the rise of antibiotic-resistant superbugs, by quickly illuminating bacteria when antibiotics are having the desired effect.

MRSA is a common and quite dangerous hospital infection that’s resistant to many drugs. Now researchers have developed a new treatment path that targets not the bacteria itself, but the toxins they produce. Tests on mice have proved promising so far.
