Antibiotic-destroying genes widespread in bacteria in soil and on people

Researchers at Washington University in St. Louis and the National Institutes of Health (NIH) have found that genes that confer the power to destroy tetracycline antibiotics are widespread in bacteria. But the researchers have also created a chemical compound that shields tetracyclines from destruction, restoring the antibiotics lethality. The findings indicate an emerging threat to one of the most widely used classes of antibiotics — but also a promising way to protect against that threat.

New CRISPR-based System Targets Amplified Antibiotic-resistant Genes

Researchers have developed a new CRISPR-based gene-drive system that more efficiently inactivates a gene rendering bacteria antibiotic-resistant. The new system leverages technology developed by UC San Diego biologists in insects and mammals that biases genetic inheritance of preferred traits called “active genetics.”

Researchers identify ‘Achilles’ heel’ of drug-resistant superbug

Researchers at The University of Texas Health Science Center at Houston (UTHealth) have identified a protein that allows vancomycin-resistant enterococci to defy antibiotic treatment and immune system attacks. Their discovery opens the door for future treatment options in the fight against antibiotic resistance.

Poll reveals risky use of antibiotics by some older adults, and opportunities for providers to improve

Half of older Americans got help from the infection-fighting power of antibiotics in the past two years, a new poll finds, but a sizable minority didn’t follow the instructions on their pill bottle. And one in five say that in the past, they’ve engaged in a risky practice: taking leftover antibiotics without checking with a medical professional.
