 The results of this study suggest that Klebsiella pneumonii is a major cause of neonatal infections worldwide, resulting in high mortality rates. Furthermore, the study found that the prevalence of neonatal CRKP infections is higher than previously thought, with the highest incidence being in low and middle-income countries. Additionally, the study revealed that the dominant carbapenemase gene in neonatal CRKP strains is Blandium, suggesting that it may be difficult to treat these infections without effective antibiotics.
