Neonatal sepsis is still a problem in the health sector, particularly in developing countries and the incidence is quite high, therefore requiring early detection and proper therapy. We report a rare manifestation of R. radiobacter infection in which sepsis occurred in a newborn infant. In patients with sepsis caused by R. radiobacter appropriate antibiotics are needed to prevent worsening. R. radiobacter is often a bacterial contaminant and rarely causes infection in humans, but in immunocompromised patients, this microorganism can be an agent in an infection. This study aims to improve understanding of sepsis caused by R. radiobacter. This study is a case report of a 27-day-old neonate with sepsis neonatal. From the result of the two-sided blood culture using VITEK 2 Compact on September 28, 2020, R. radiobacter was detected. Intravenous Meropenem was administered from day 20 patient in hospital but the patient's condition gradually deteriorated, and the patient died 28 days after birth. R. radiobacter was rarely reported as a pathogen. In immunocompromised patients, delayed detection and inadequate treatment can increase morbidity and mortality.
