Using genome sequencing, scientists have tracked the evolution of the antibiotic-resistant bacterium Klebsiella pneumoniae sequence type 258 (ST258), an important agent of hospital-acquired infections. While researchers had previously thought that ST258 K. pneumoniae strains spread from a single ancestor, the team showed that the strains arose from at least two different lineages.
