'''''Staphylococcus intermedius''''' is a [[Gram-positive]], [[catalase]] positive member of the [[bacteria]]l genus ''[[Staphylococcus]]'' consisting of clustered [[coccus|cocci]]. Strains of this species were originally isolated from the [[anterior nares]] of pigeons, dogs, [[Feline zoonosis|cats]], mink, and horses.  Many of the isolated strains show [[coagulase]] activity.&lt;ref&gt;{{cite journal|last=Hájek|first=V.|title=Staphylococcus intermedius, a New Species Isolated from Animals|journal=International Journal of Systematic Bacteriology|date=1 October 1976|volume=26|issue=4|pages=401–408|doi=10.1099/00207713-26-4-401|doi-access=free}}&lt;/ref&gt; Clinical tests for detection of [[methicillin-resistant Staphylococcus aureus|methicillin-resistant ''S. aureus'']] may produce false positives by detecting ''S. intermedius'', as this species shares some phenotypic traits with methicillin-resistant ''S. aureus'' strains.&lt;ref&gt;{{cite journal|last=Pottumarthy|first=S|author2=Schapiro, JM |author3=Prentice, JL |author4=Houze, YB |author5=Swanzy, SR |author6=Fang, FC |author7= Cookson, BT |title=Clinical isolates of Staphylococcus intermedius masquerading as methicillin-resistant Staphylococcus aureus.|journal=Journal of Clinical Microbiology|date=December 2004|volume=42|issue=12|pages=5881–4|doi=10.1128/JCM.42.12.5881-5884.2004|pmid=15583331 |pmc=535261}}&lt;/ref&gt; It has been theorized that ''S. intermedius'' has previously been misidentified as ''S. aureus'' in human dog bite wound infections,&lt;ref&gt;{{Cite journal|last1=Talan|first1=D.
