title: [Streptococcus dysgalactiae subspecies equisimilis bacteremic erythroderma in a pediatric patient: a case report and review of literature].
abstract: Infections caused by pyogenic streptococci are commons in pediatric ages. However, in the last decades there has been an increase in the isolation of no A or B Streptococci. We report a case of a 6 years old girl, who presents fever for 5 days and erythroderma. Streptococcus dysgalactiae subspecies equisimilis was isolated from blood cultures. She receives antibiotics for 14 days with ß-lactams with a good clinic evolution with normalization of the inflammatory parameters. This agent ß-hemolítico presents antigens of Lancefield groups A, C and G, and a great similitude regarding virulence factors, with Streptococcus pyogenes. Frequently in old patients, few reported cases in pediatric population. First line treatment remains ß-lactam antibiotics for which there are no reports of increasing resistance.
