Figure 8. Alignment of exemplar IncFII plasmid from a Shigella sonnei strain during an epidemiologic and genomic investigation of sexually transmitted Shigella sonnei from presumptive men who have sex with men, England, 2016–2023. The strain fell within the 10 single-nucleotide polymorphism linkage cluster t10.1814 and strain 01233204 (GenBank accession no. SRR29176725), showing the cassette containing blaCTX-M-15 (highlighted in red) has moved to the chromosome. 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
