Maximum-likelihood single-nucleotide polymorphism tree of Shigella flexneri strain 2a isolates from California, USA (UCLA_689, 2020, and UCLA_1207, 2023), and the United Kingdom. Analysis was performed by using CLC Genomics Workbench version 22.0.2 (https://www.qiagen.com) single-nucleotide polymorphism analysis for microbial relatedness workflow and using reference strain Shigella flexneri 2a strain 981. GBRU, UK Gastrointestinal Bacterial Reference Unit; UCLA, University of California Los Angeles. Scale bar indicates nucleotide substitutions per 100 sites.
