Figure 4. Maximum-likelihood phylogenetic tree of the Shigella sonnei clonal complex 152 within the 10 single-nucleotide polymorphism linkage cluster t10.1814 (n = 125) found during an epidemiologic and genomic investigation of sexually transmitted S. sonnei from presumptive men who have sex with men, England, 2016–2023. A total of 125 isolates included in tree. Sequence read run accession is sample identification, additional information provided is gender, presence of blaCTX-M gene variants, and association with travel. Presumptive men who have sex with men was defined as cases among male adults (>16 years of age) without a history of travel or where travel history was unknown.
