[2][3] The bacterium was first isolated from a human skin infection in Cornwall, United Kingdom.

Another SIG bacterium, S. pseudintermedius, has also been implicated in cutaneous infections in humans–as a result of zoonotic transmission from domestic animals.

[4][5] The other SIG species have been isolated from various wild and domestic animals; such as dogs, cats, horses, camels, and dolphins, among others.

[6] S. cornubiensis was first described in a 2018 paper that discussed improved methods of detecting SIG species.

Designated strain NW1, S. cornubiensis was distinguished from other samples (all identified as S. pseudointermedius) due to differences in the sodA and hsp60 sequences.
