Samples were collected from infected breeder chickens across the UK (n = 161), USA (n = 25), and the Netherlands (n = 5). Grouped bar charts show the relative proportion of isolates belonging to CC5 by country (1a), year of collection (1b), and disease site (1c). MLST clonal complexes were assigned based on shared sequence at five or more MLST house-keeping loci.
