Mycobacterium pinnipedii

Mycobacterium pinnipedii is a member of the Mycobacterium tuberculosis complex which primarily infects seals. It is a slowly growing Mycobacterium. The species is named after the Pinnipeds, the organisms from which "M. pinnipedii" was first isolated.
In 2014, a genetic study showed that Peruvian human skeleton dating to 1000 CE had been infected with a form of tuberculosis most closely related to "M. pinnipedii", suggesting that seals had served as a vector for transmission of tuberculosis from the Old World to the New.
