Late-onset Leclercia adecarboxylata sepsis in a premature neonate

The epidemiology, etiology and outcome of neonatal sepsis are changing over time. while monitoring longitudinal trends in neonatal sepsis in our institution, we encountered a case of late-onset neonatal sepsis due to leclercia adecarboxylata. a gram-negative rod previously not encountered in the clinical setting, l. adecarboxylata has recently emerged as a human pathogen, primarily in immunosuppressed patients. this report describes the clinical and laboratory features of this case of late-onset l. adecarboxylata sepsis, and reviews significant features of infection associated with this emerging pathogen.
