What is Staphylococcus aureus sim test results?

Staphylococcus aureus is negative for motility, and positive for the indole production. The SIM test tests for sulfur reduction, indole production and motility. Positive for indole production means tryptophan is broken down into indole and pyruvate and will give a red color. Motility, you will see the bacteria move outside of the stab. Positive for sulfur reduction will give a black color in the medium.

What is smaller in size Staphylococcus epidermidis or E. coli?

Staphylococcus epidermidis is generally smaller in size compared to E. coli. Staphylococcus epidermidis typically measures about 0.5 to 1.0 micrometers in diameter, while E. coli is usually around 1.0 to 3.0 micrometers in length and 0.5 micrometers in diameter. Thus, Staphylococcus epidermidis is considered to be smaller overall.
