Question

You have a culture of bacteria that you suspect is either staphylococcus aureus or streptococcus pyogenes. is there any morphological difference between the two?

Answer 1

Yes. Staphylococcus aureus differs from Staphylococcus pyogenes because it grows in clusters, whereas Chain-like  growth.

Although all infections have the potential to be dangerous, Staphylococcus is associated in the microbiological literature. Staphylococcus aureus tends to cause more widespread illness, such as the development of abscesses and purulent discharge. Between erysipelas to necrotizing fasciitis, Staphylococcus pyogenes has been associated to a wide range of illnesses.

In order to distinguish between staphylococci that are catalase positive and catalase negative, the catalase test is crucial. Agar slants or broth cultures are flooded with several drops of 3% hydrogen peroxide to conduct the test. Cultures that have catalase immediately bubble. Gram-positive cocci include streptococci and staphylococci. Streptococci develop in chains, whereas Staphylococci form clumps. Because Staphylococci may make catalase, they can be distinguished using the catalase test.
