Objective: The aim of the analysis was to present two cases of a late onset sepsis (LOS) caused by Klebsiella pneumoniae (KLE) recognized in prematurely delivered siblings, born within the interval of one year.
Study Design and Result: It was a retrospective study. The first child was born after 32 weeks of pregnancy and the gestational age of the second infant was 29 weeks of pregnancy and died in the course of sepsis without positive blood culture examination. In the second child, sepsis with the same clinical signs was diagnosed, the strains of KLE were isolated from the blood and from the mother's breast milk: the strains were identical, confirmed with PFGE.
Conclusion: Presented results suggest that the source of infections in both siblings was contaminated breast milk. The targeted therapy used in the mother allowed breastfeeding the child.
