Detection of Streptococcus pneumoniae serotypes causing invasive and non-invasive infections using whole-genome sequencing

Objective. Seroyping of the Streptococcus pneumoniae strains obtained from patients with invasive and non-invasive forms of pneumococcal infection circulating in Russia using whole-genome sequencing. Materials and Methods. The 144 invasive and 90 non-invasive S. pneumoniae strains isolated in 2002– 2023 during the multicenter epidemiological study «PEGASus» were investigated. Real-time PCR and whole-genome sequencing were used to determine serotypes. The 16 serotyping targets were examined by PCR technique. Whole-genome sequencing was performed on the Illumina equipment.

Current methods of capsular typing of Streptococcus pneumoniae: possibilities and availability for local laboratories

Pneumococcal conjugate vaccines contain a limited number of serotype-specific antigens of S. pneumoniae. It is important for vaccination programmes effectiveness assessment to control a variety of circulating S. pneumoniae serotypes. This review …
