NO, s. epidermidis does not show up positive in an acid fast stain. The acid fast stain is a differential stain that differentiates cells with mycolic acids in their cells wal…ls with those who do not. cells with mycolic acid are therefore acid fast. s epidermidis does not contain this waxy substance in their cell wall so it doesnt fall into this category.
No, it is negative.
Positive and its shape should be round (coccus). :)
S. epidermidis also accounts for two of every five cases of prosthetic valve endocarditis. Prosthetic valve endocarditis is an infection that develops as a complication of the… implantation of an artificial valve in the heart.
It is gram-positive
No. MacConkey agar is used to grow gram negative bacilli S. epidermidis is gram positive cocci
It grows on the agar but does not ferment the mannitol
Staphylococcus epidermidis is coccoid (spherical) about 1.0μm diameter. It stains Gram Positive (Purple).
It does not have capsules
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.
Escherichia Coli is a gram-negative bacterium whereas Staphylococcus Epidermidis is a gram-positive bacterium, staph. Epidermidis will have thicker cell walls.
Staphylococcus epidermidis is a Gram-positive bacterium, which is part of the normal skin flora. It has been tested as negative for indole production.
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 y…ou have done some type of growth on salt agar and tested its susceptibility to novobiocin and perhaps lysostaphin.
