Empiema pleural por Streptococcus grupo anginosus en un preescolar y revisi贸n de la literaturaStreptococcus anginosus pleural emphyema in a child. Case report and review Left pneumonectomy in a child with congenital pulmonary malformation was performed two months prior to admission. Within one week he had high fever. Chest CT scan showed massive left pleural effusion. Both Streptococcus anginosus group and Prevotella spp. grew from the fluid obtained by pleural punction. Antimicrobial therapy was immediately initiated with clindamycin and penicillin. Streptococus anginosus group is quite confusing in terms of classification and taxonomy. Now it is well recognized that three species belong to this genera: S. anginosus S. constellatus and S. intermedius. They all are considered normal flora of the oropharynx, nasopharynx, gastrointestinal tract and vagina but also they have been identified as agents of suppurative infections in children and adults. Many reports show adequate response to penicillin, however there is some emerging resistance in strains isolated in other studies. In this article we also suggest some diagnostic and microbiologic recommendations.
