I think, srteptococcus is Aerotolerant organism, because it doesn't use oxygen for metabolism, but are able to grow in oxygen. Even they are able to grow with oxygen the amount of oxygen required is less than normally exists in air.
St. aureus is an obligate aerobe which means it needs a supply od molecular oxygen (O2) to live.
Facultative- can grow with or without oxygem.
Facultative anaerobic
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.
correct
yes
Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.

Staphylococcus epidermidis belongs to the genus Staphylococcus. It is part of the human skin flora and is a non-motile bacterium.
Is stpylococcus epidermidis is largest
Staphylococcus Epidermidis does return a gram positive result on the citrate lab test. Gram stains will produce these results on slides.
1. Staphylococcus aureus 2. Staphylococcus epidermidis 3. Staphylococcus saprophyticus
staphylococcus epidermidis
no it cannot, it is nitrate reduction negative
Staphylococcus epidermidis Staphylococcus aureus Enterococcus Neisseria sp. Haemophilus influenzae Corynebacteria
i have ni have no clue your on your own pick up a book and figure it out
Gram + cocci, facultative anaerobes, catalase 2) Most Staph reside harmlessly as normal flora of skin. 3) Staphylococcus epidermidis 4) Staphylococcus aureus - skin / wound infections, food poisoning 5) Staphylococcus saprophyticus - UTI
Yes it is. This test can be used to differentiate between S. aureus (which is positive) and S. epidermidis (which is negative).
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.
