Once restricted to northern China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution due to the evolution of commensalism with humans.

NY Times article about the study.
How the Brown Rat Conquered New York City (and Every Other One, Too)

After spreading slowly for thousands of years, the scientists found, brown rats scampered over much of the planet in just the past three centuries. And once brown rats settle into a new city, the new study suggests, they repel all newcomers — a finding that could have big implications for our health.
To Dr. Munshi-South, that’s good news. “It’s unlikely that a lot of diseases are going to be entering cities on rats walking into the local rat population,” he said.
