Bovine-adapted clonal complexes Staphylococcus aureus (S. aureus CCs) appear to have derived from human CCs and acquired bovine affinities through a series of spill-over events that resulted in the acquisition of various mobile genetic elements (MGEs). Several hosts have a high prevalence of the CC398 lineage. This lineage seems to have started in humans via reverse zoonosis, then it spread to pigs, then it returned to humans via pig zoonosis, and ultimately it spread to other species.
