Citrate Positive (+ve)
Coagulase Positive (+ve)
Gas Negative (-ve)
Gelatin Hydrolysis Positive (+ve)

People also ask, is Staphylococcus aureus citrate positive?

Phenotypic identification of Staphylococcus aureus Single colonies were tested with tube coagulase and DNase test and growth on MSA. Since citrate is utilized by enterococci [16], pure colonies of Gram positive, Catalase positive staphylococci (catalase tests preceded coagulase reactions) were used.

One may also ask, how do you identify Staphylococcus aureus? A clinical isolate is presumptively identified as S. aureus by means of several simple procedures: Gram stain: Gram-positive cocci, occurring singly, in pairs,or “bunches of grapes.” Catalase test: Staphylococci are catalase-positive, distinguishes them from Streptococci which are catalase-negative.

Keeping this in view, is Staphylococcus aureus indole positive or negative?

aureus isolates, 17 (85%) were found as positive for coagulase, catalase, methylene red, Voges-proskauer and hemolysis tests and negative for oxidase and indole tests. They also produce acid from glucose, lactose and sucrose.

Does Staphylococcus aureus test positive for urease?

aureus. The bacterium should have been negative for urease and positive for mannitol. A urea broth test identified the gram negative bacterium as Proteus vulgaris.
