Cross contamination between 4 exclusively terrestrial and exclusively marine hosts is unlikely suggesting the divergence of 5 the different species of the genus Brucella may have taken place 60 million years ago, 6 concomitant with the radiation of their mammalian hosts (Artiodactyla) from other 7 mammalian orders. 8 9
