- How is Staphylococcus aureus differentiated from other Staphylococci species on Mannitol Salt agar?
Homework Answers
Staphylococcus aureus can be determined using mannitol salt agar test. S. aureus is capable of fermenting mannitol. Fermentation of mannitol is indicated by acid production. The media which contain phenol red as indicator will turns to yellow on acid production. Coagulase positive staphylococcus that is S. aureus will produce yellow colony with yellow baground indicating acid production and other staphylococcus sp. That is coagulase negative produce red colonies in red baground. Hence S.aureus can be easily identified.

On a mannitol-salt agar plate, a bacterium grows on the plate, and turns medium color from light orange to bright yellow. The color indicator is phenol red. This bacterium must be capable of: Select one: O a. Fermenting lactose to make acidic by-products. O b. Utilizing citrate as a main carbohydrate source to grow. O c. Fermenting glucose to make acidic products, which lowers the pH of the MSA agar. O d. Fermenting mannitol to make acidic products,...

May you please put this in layman's terms? ABSTRACT Coagulase-negative staphylococci (CoNS) and Staphylococcus aureus are part of the natural flora of humans and other mammals. We found that spent media from the CoNS species Staphylococcus caprae can inhibit agr-mediated quorum sensing by all classes of S. aureus. A biochemical assessment of the inhibitory activity suggested that the S. caprae autoinducing peptide (AIP) was responsible, and mass spectrometric analysis identified the S. caprae AIP as an eight-residue peptide (YSTCSYYF). Using...
