Genetic sleuthing reveals rapid evolution of MDR Klebsiella outbreak

Scientists were able to determine that the strain that had sickened the patient had been in circulation in the hospital for at least a year prior to the patient's death, spreading between patients and throughout the wards of the hospital. It even traveled among the three campuses of the hospital, which were miles apart. The analysis also found that the isolates of the highly drug-resistant outbreak strain were carrying multiple antibiotic resistance genes and plasmids.
