Composition of genetic clusters enrolling Portuguese isolates. Cluster were identified after applying a conservative threshold of 1.5% allelic differences within each low-level genogroup, after sub-minimum spanning tree generation maximizing the shared loci between isolates at this level. PT Cluster – Cluster composed exclusively of ≥ 3 PT isolates; International Cluster – Cluster composed of ≥ 3 isolates of which ≥ 2 hail from Portugal; International Single PT – Cluster composed of ≥ 3 isolates of which only one is from Portugal; PT Pair – Pair of two isolates collected in Portugal; International Pair – Pair of two isolates with one collected in Portugal and the other from another country.

纳入葡萄牙来源分离株的遗传簇组成情况。各遗传簇的鉴定流程为：先生成次极小生成树(sub-minimum spanning tree)，以最大化该层级下分离株间的共享位点(shared loci)数量，随后在每个低级基因群(low-level genogroup)内设置1.5%的等位基因差异作为严格阈值。PT簇(PT为葡萄牙Portugal的缩写) — 仅由≥3株葡萄牙来源分离株构成的簇；国际簇 — 由≥3株分离株构成，其中≥2株源自葡萄牙；仅含1株葡萄牙分离株的国际簇 — 由≥3株分离株构成，其中仅1株源自葡萄牙；葡萄牙分离株对 — 由在葡萄牙收集的2株分离株组成的配对；跨国分离株对 — 由1株在葡萄牙收集、1株源自其他国家的2株分离株组成的配对。
