A Case of Streptococcus Constellatus Bacteremia Secondary to Respiratory Syncytial Virus Bronchiolitis in a Neonate

Common causes of bacteremia in the neonatal period include group B streptococcus, listeria, and E. coli. We report a rare case of neonatal bacteremia with culture-positive Streptococcus constellatus. Streptococcus constellatus is part of the normal flora of the orogenital regions of the body; when found elsewhere, it causes pyogenic abscesses in the brain and digestive tract. In this case, the Streptococcus constellatus bacteremia was secondary to prolonged hospitalization in a patient with respiratory syncytial virus (RSV) bronchiolitis. This report serves to make physicians aware of and to define treatment options for Streptococcus constellatus as a rarely isolated organism that can cause asymptomatic bacteremia in a neonate while demonstrating the treatment strategy successfully employed.
