This study analyzes the evolutionary history and host adaptation of two GBS clonal groups, revealing host switching, regional AMR gene distribution differences, and biased sampling in multi-host pathogens.

The paper reprocesses SARS-CoV-2 genomic data to correct systematic errors in phylogenies using a novel assembly tool, resulting in a cleaner global tree of 4.47 million samples.

This paper introduces GBS-SBG, a serotyping tool for Group B Streptococcus using genome sequencing, achieving high concordance with PCR-based methods on both short-read and assembly data.

This paper introduces a hybrid metagenomic assembler that improves assembly quality and enables high-resolution analysis of resistance determinants and mobile elements in the human gut microbiome.

The paper identifies specific bacterial species associated with gut microbiome recovery after antibiotic use and shows their role in promoting microbial diversity and preventing pathogen colonization.
