Streptococcus constellatus: agente etiológico asociado en empiema pleural

Streptococcus constellatus is a commensal microorganism in man but may cause infections in different locations. We report a 59 years old male with severe sequelae of a previous cerebrovascular accident that consulted in the emergency room for fever of 15 days of evolution. A right empyema was diagnosed. The bacteriological culture of the effusion disclosed the presence of Streptococcus constellatus and two anaerobic strains (Prevotella intermedia and Fusobacterium urealyticus). The patient was treated with a pleural drainage and received ceftriaxone and clindamycin during six weeks. He was discharged in good conditions and is asymptomatic after eight months of follow up.
