Multidrug-resistant Klebsiella pneumoniae in a pediatric ICU: Emergence of newly identified ST7120 and the first report of ST792 in Taiwan

This MDR <i>K. pneumoniae</i> cluster involved a newly identified ST, ST7120, and the first reported case of ST792 in Taiwan, both were associated with prolonged colonization and invasive disease. Molecular typing revealed complex transmission routes not detectable through phenotypic methods alone. Integrating molecular epidemiology into routine MDRO surveillance could improve early outbreak detection and containment.
