Cross-host transmission of Riemerella anatipestifer to chickens: Genomic evolution and identification of the novel vapX-like- vapD toxin-antitoxin system
{{output}}
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 characteri... ...
