|Etymology:||Genus name: bunch of grape-like cocci (coccus means a grain or berry)|
Species epithet: refers to the similarity with S. intermedius.
|Type Strain:||LMG 22219 = CCUG 49543|
||Small round, greyish white, opaque colonies (1-2 mm in diameter) with smoth margin.
Does often give a double hemolysis zone on blood agar [clear (complete) narrow inner zone and a broad turbid (patial) outer zone].
The complete hemolysis of Staphylococcus spp. is caused by an α-hemolysin and the partial hemolysis by a β-hemolysin. Cf. Streptococcus spp.
||Cocci (0.5-1.5 µm in diameter), arranged in groups|
|Gram +/Gram -:||G+|
|Other Enzymes:||Coagulase +, DNase +, esculinase - and urease +|
|Biochemical Tests:||Voges-Proskauer +|
|Fermentation of carbohydrates:
Other carbohydrates: D-xylose -.
||S. pseudintermedius is a lactose fermenter, which can easily be seen on both purple agar och CLED agar.|
|16S rRNA Seq.:|
||About 70 species and subspecies have been described within the genus Staphylococcus. S. pseudintermedius is closely related to S. intermedius, S. delphini and S. schleiferi.|
|Comment:||S. pseudintermedius is coagulase-positive and can, therefore, be confused with primarely S. intermedius, but also with S. aureus. Purple agar with maltose is used for differentiation of S. aureus and S. pseudintermedius (see above).|
|New names of taxa within the classification category phylum|
During October 2021, an article was published by A. Oren och G.M. Garrity, in which new names are proposed for a number of taxa within the classification category phylum. This has resulted in many discussions in social media about whether it was really necessary to make these changes, which have created confusion among microbiologists and other professionals who come into contact with bacteriology.Published 2022-09-28.
