Recently, a team of researchers at the University of Massachusetts Amherst has discovered a novel mechanism of drug resistance in a pathogen. This finding could lead to improved treatments, as it may help explain why some infections are more resistant to antibiotics than others. The researchers used a combination of genetic, biochemical, and structural analyses to identify a novel resistance mechanism in a Gram-negative pathogen called Acinetobacter baumannii. They found that the bacteria can use two different pathways to transport drug molecules across the cell membrane, which helps them to become more resistant to certain antibiotics. This could have a significant impact on our understanding of drug resistance and how to effectively treat infections.
