Genomic tool untangles how microbes spread—even when they look almost identical

Researchers have developed a powerful new tool that can track how microbes spread between people with unprecedented precision, offering new ways to prevent infections and improve treatments in the future. The research, published April 24 in Nature Microbiology, describes how the new tool, called TRAnsmision Clustering of Strains (TRACS), uses genomics to distinguish between closely related strains of microbes.
