The patient, who was born spontaneously to a 22-year-old mother as G1 P1 Y1 with a weight of 2605 g at 37 weeks of gestation, had an Activity, Pulse, Grimace, Appearance and Respiration (APGAR) of 8 and 5, respectively, at the first and fifth minutes APGAR 9. Physical examination revealed that the patient’s general condition was moderate: body temperature was 36.7 °C, respiratory rate was 68 beats per minute, heart rate was 146 beats per minute, blood pressure was 59/33 mmHg, saturation was 92%, both hemithoraxes participated equally in respiration, consciousness was clear, and the sucking reflex was weak. Because the mother had a history of premature membrane rupture for 22 hours, ampicillin and gentamicin were given intravenously after a blood culture. Leuconostoc lactis was grown in a blood culture sent by the patient. On the 12th day of her hospitalization, the patient was discharged with full oral feeding, had started to weigh regularly, and had good general condition, oral intake, and activity. Leuconostoc species should be kept in mind in vancomycin-resistant gram-positive infections. It should be kept in mind that Leuconostoc lactis may be a cause of Early-onset neonatal sepsis, albeit very rarely. Keywords: Newborn, Leuconostoc lactis, sepsis
