Abstract excerpt
Riemerella anatipestifer (R. anatipestifer), a well-known waterfowl pathogen, increasingly threatens Chinese poultry by spreading to chickens. The genetic differentiation and host adaptation following cross-host transmission remain unclear. Here, we characterized a highly virulent, multidrug-resistant chicken-source strain (SDAU-RA1) and performed comparative genomics with global R. anatipestifer strains to...
