Transmission of multidrug-resistant salmonella enterica subspecies enterica 4,[5],12:i:-Sequence type 34 between europe and the United States

Abstract

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.
