Abstract

ABSTRACTThe incidence of scarlet fever cases remains high in China. Here, we report the complete genome sequence of a Streptococcus pyogenes isolate of serotype M12, which has been confirmed as the predominant serotype in recent outbreaks. Genome sequencing was achieved by a combination of Oxford Nanopore MinION and Illumina methodologies.

Highlights

  • The incidence of scarlet fever cases remains high in China

  • De novo assembly in combination with the Illumina short reads and Oxford Nanopore Technologies (ONT) long reads generated a single contig with a length of 1,939,733 bp and a GϩC content of 38.5%

  • Genome sequence alignment shows that TJ11-001 harbors four mobile genetic elements, including ␾HKU.ssa and ICE-HKU937, which may both play an important role in the clonal expansion of M12 group A Streptococcus (GAS) species, which cause scarlet fever

Summary

Introduction

The incidence of scarlet fever cases remains high in China. Here, we report the complete genome sequence of a Streptococcus pyogenes isolate of serotype M12, which has been confirmed as the predominant serotype in recent outbreaks. Illumina sequencing generated 2,679,224 reads and 335 Mb of high-quality raw data. De novo assembly generated 25 contigs of 1,904,680 bp length.
