Outbreak of Yersiniabactin-producing Klebsiella pneumoniae in a Neonatal Intensive Care Unit

The Gram-negative bacterium Klebsiella pneumoniae is a
frequent pathogen causing outbreaks in neonatal intensive care units. Some
Enterobacteriaceae can acquire the ability to sequester iron from infected
tissue by secretion of iron-chelating compounds such as yersiniabactin.
Here we describe an outbreak and clinical management of infections
because of a highly virulent yersiniabactin-producing, nonmultiresistant K.
pneumoniae strain in a neonatal intensive care unit. Outbreak investigation
and effectiveness assessment of multidisciplinary infection control measurements
to prevent patient-to-patient transmission of highly pathogenic K.
pneumoniae were undertaken.
