Recurrent bacteremia with different strains of Streptococcus pyogenes in an immunocompromised child

摘要

We report an immunocompromised child who experienced two episodes of bacteremia due to Streptococcus pyogenes. Random amplification of polymorphic DNA profiles, emm genotypes, superantigen profiles, antimicrobial susceptibility, and resistance-related genes were investigated, and the results showed different profiles between the two isolates. This is the first report describing recurrent bacteremia caused by different strains of S. pyogenes. (C) 2016 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.
