- Six strains of multiresistant Klebsiella pneumoniae, which produce the NDM-1 enzyme, were found during an outbreak affecting neonatal patients in a Colombian hospital.
- Molecular examination revealed that all strains contained the blaNDM-1, qnrA, and intI1 genes and shared a close genetic relationship.
- These strains represent a new sequence type (ST1043) never documented before, marking the first identification of NDM-1-producing bacteria in South America.
