yes. it is a weak positive for this test though. Better idea for identification would be to run some fermentation tests, like mannitol, sucrose, trehalose and mannose. after you have done some type of growth on salt agar and tested its susceptibility to novobiocin and perhaps lysostaphin.

Is Staphylococcus aureus positive for catalase?
correct
Is staphylococcus aureus methyl red positive?
yes
Do nitrogen protons have a charge?
All protons -- whether in nitrogen or elsewhere -- are identical, and all have a positive charge.
What is positive about NH3 Nitrogen has a strong positive charge hydrogen is negative or they are covalently bonded?
they are covalently bonded
What does a reduction potential chart show?
How likely chemical species are to gain electrons and therefore, be "reduced". Reduction potential is measured in volts(V) and the more positive the reduction potential value, the more likely it will be reduced.
Is staphylococcus epidermidis citrate positive?
Staphylococcus Epidermidis does return a gram positive result on the citrate lab test. Gram stains will produce these results on slides.
Is staphylococcus aureus positive for gelatin?
Yes it is. This test can be used to differentiate between S. aureus (which is positive) and S. epidermidis (which is negative).
Does staphylococcus aureus test positive for nitrate reduction?
S. aureus is Nitrate Reduction test positive....
What are results of Imvic test on staphylococci?
Staphylococcus epidermidis indole test - negative methyl red - negative voges proskauer test - positive citrate test - no idea
Is S epidermidis gram negative or gram positive?
gram positive..
What are the EMB test results for Staphylococcus epidermidis?
The Eosine Methylene Blue test is selective for only gram-negative bacteria. It is possible for gram-positive bacteria to grow, but it would barely grow. Staphylococcus are gram-positive spherical bacteria. So it would not grow on the Eosine methylene Blue Agar.
Does staphylococcus epidermidis test positive for hydrogen sulfide?
This is a bacterium that is one of more than 40 species for the bacteria. It can attack people who have something wrong with their immune systems.
How is Staphylococcus albus good for humans?
Staphylococcus albus, now known as Staphylococcus Epidermidis, is present on people's skin naturally and typically is not harmful unless it is introduced into the person's system via an injury to the skin that disrupts the skin's integrity, such as a laceration. It can also be introduced into the body via a urinary catheter.
Is staphylococci epidermidis gram-negative or gram-positive?
gram positive
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 the gram reaction of s epidermidis?
Gram positive, coccus shape.
What is the shape of staphylococcus aureus?
Staphylococcus is a coccus and so indiviual cells are round in shape. Groups of cells typically form grape like clusters because they divide along two planes rather than the chains formed by Streptococcus which only divide along one plane.
