title: Late-onset Streptococcus pasteurianus sepsis in a preterm baby in a neonatal intensive care unit.
abstract: Apnea, cyanosis, lethargy and prolongation in capillary filling time developed on the postnatal 37(th) day in a preterm baby who was born at the 30(th) gestational week with a birth weight of 1 300 g. Acute phase reactants and immature/total neutrophil count ratio were found to be high. The patient who was diagnosed with sepsis was successfully treated with meropenem which was started empirically. In his blood culture Streptococcus pasteurianus grew. S. pasteurianus is in the subgroup of streptococcus bovis which is one of the D group streptococci and its previous name is S. bovis type II/2. In the literature, there are very few cases of neonatal infection related with this bacterium. As far as we know, this is first case of neonatal sepsis caused by S. pasteurianus in Turkey. In addition, we tried to determine the clinical properties of neonatal infections arising from S. pasteurianus by reviewing the literature.
