Abstract: The pathogens Streptococcus pneumoniae and Streptococcus pyogenes can cause serious diseases. In this work effective carrier-coupled antisense peptide nucleic acids (PNAs) against S. pneumoniae were identified. The counteranion pyrenebutyrate was investigated for its ability to improve uptake of CPP-PNAs in streptococci. Furthermore, transcriptomic effects of CPP-PNA on streptococci were examined. As Galleria mellonella is an increasingly popular infection model organism, additionally the S. pyogenes specific immune response of the larvae was investigated using a proteomics approach.
