The study by Price et al. highlights the emergence in multidrug resistance S. aureus in a livestock associated lineage, and the subsequent transmission to humans. Of note, the ancestral host of the lineage is predicted to be originally human, raising questions about agricultural practices that may have contributed to the emergence of drug resistance.
There is also a commentary on the paper here: http://mbio.asm.org/content/3/2/e00082-12.full
Looking forward to a good discussion.
