First of all, its S. pseudintermedius ¬†(just rectifying you and not being rude or anything! ūüôā )

S. pseudintermedius can be biochemically misidentified as S. aureus (be cautious!!).  It  has been  recently identified as new coagulase positive species of S. intermedius group. Few phenotyphic  tests such as PYR test (+), mannitol fermentation test (weakly and delayed), clumping factor activity test (-),  ONPG test(+),  VP or acetoin test (+),  acriflavine sensitivity test (S ). Novobiocin sensitivity test (S)  can be considered.  Genotyphic tests targeting mec A , nuc  genes of S. aureus and tuf gene of Staphylococcus genus can also be performed.

I have attached a link for  the  comparative phenotypic characteristics .

I hope its helpful enough.
