Multidrug-resistant Salmonella enterica subspecies enterica 4,[5],12:i:- sequence type 34 represents a worldwide public health risk. To determine its origin in the United States, we reconstructed a time-scaled phylogeny with a discrete trait geospatial model. The clone in the United States was introduced from Europe on multiple occasions in the early 2000s.
多重耐药的沙门氏菌肠亚种 4,[5],12:i:- 血清型 34 代表了一种全球性的公共健康风险。为了确定其在美国的起源,我们使用离散特征地理空间模型构建了一个时间尺度的系统发育树。美国的这个克隆是在 21 世纪初的多次从欧洲传入的。
