"In the case of MRSA, these bacteria have also spread in hospitals almost world-wide," says Jukka Corander, professor at the University of Helsinki, who was a member of the international research team that mapped several millennia of the evolution of the staphylococcus.

In their extensive study, the researchers sequenced whole genomes of the superbugs from a large sample from different animals as well as humans, and were able to study the DNA changes that helped the bacteria to adapt to new host organisms during thousands of years.

Analysis - Humans - Hosts - Superbugs - DNA

Based on genome analysis, humans were most probably the original hosts to these superbugs, and judging from DNA changes, the ability to colonise domestic animals appeared in an age when the first animals were domesticated to become livestock on farms.

In the study, published recently in Nature Ecology...
