Unfortunately, the original version of this article  contained missing infromation. In the study procedures it was mentioned that samples were to be inoculated onto chocolate agar (otorrhea samples were inoculated onto chocolate agar with bacitracin), blood (with gentamycin) and MacConkey agar. Instead, the samples have been routinely plated on Columbia agar with sheep blood, colistin/nalidixin columbia (CNA) agar with sheep blood, McConkey agar, supplemented chocolate agar and Sabouraud agar. The use of the different agar does not have any impact on the study results and conclusions. We express our gratitude to Mark van der Linden and Matthias Imöhl from the German National Reference Center for Streptococci, who performed all microbiological analyses.
