Study of KPC-producing Gram-Negative Bacilli (KPC-GNB) strains from one inpatient during hospitalization. Klebsiella pneumoniae strain:HA3pKp

The aim of this work was to investigate genomic dynamics of both colonizing and infecting strains of KPC-producing Gram-Negative Bacilli (KPC-GNB) from one inpatient during hospitalization. Pandemic KPC-producing Klebsiella pneumoniae sequenciotype (ST) 258 (HA3) was colonizing an inpatient who later was infected by KPC-producing Escherichia coli ST730 (HA4) and subsequently by KPC-producing K. pneumoniae ST11 (HA15) in a hospital setting from Ciudad Autonoma de Buenos Aires during the year 2019.
