The Majority of Typhoid Toxin-Positive <i>Salmonella</i> Serovars Encode ArtB, an Alternate Binding Subunit

While previous reports had suggested that the typhoid toxin (TT) could potentially use ArtB as an alternate binding subunit, this was thought to play a minor role in the evolution and biology of the toxin. In this study, we establish that both TT genes and artBSalmonella entericaentericaSalmonell
