Members of the Staphylococcus intermedius group (SIG) and host associations based upon data presented in references 2, 3, and 11. The animal sources of the type strains are highlighted, and organisms from whom various SIG members have been recovered are also listed. The S. cornubiensis type strain was isolated from a human; however, human isolates associated with all SIG members, including the S. cornubiensis type strain, probably reflect transmission from animals.
