Researchers identify the LypABC system used by bacteria to release gene transfer agents. This discovery explains how ancient viral components are repurposed to spread antibiotic resistance across microbial populations.
Study in Indonesia uses DNA sequencing to track antibiotic-resistant E. coli in abattoir wastewater and rivers, revealing potential spread routes and highlighting the urgency of enhanced surveillance.
Global rivers face antibiotic pollution, promoting drug resistance and harming aquatic life. A study estimates 8,500 tons of antibiotics pollute rivers annually, even after wastewater treatment.
Researchers developed a metal-free, blue light method using modified carbohydrates (thiosugars) to combat antibiotic-resistant infections, cancer, and gram-negative pathogens like Pseudomonas aeruginosa. This advance enhances drug delivery and reduces toxicity.
"For example, AI models could be used to improve molecular diagnostics to find new forms of multi-resistant bacteria or for monitoring wastewater treatment plants and environments where antibiotics are present," says Erik Kristiansson.
