No. Impetigo is usually caused by Staphylococcus aureus, gram positive cocci.
It is gram-positive
No, Staphylococcus Aureus is a gram positive facultative anaerobe. It has a cell wall surrounding a peptidoglycan layer, however does not produce an endospore like many other gram positive bacteria. Staphylococcus Aureus is a cocci shaped bacteria with pyogenic properties.
gram-positive, catalase-positive, and coagulase-positive cocci
E. coli is a gram-negative bacteria.S. aureus is a gram-positive coccus. It is a coccus because its shape is round (from the Greek kokkos=grain).
Post ID Special:Contributionssaid: "blue-violet.....because it is a gram-negative bacteria"Wrong...the color is correct, but S. aureus is gram-POSITIVE.
Learn to use wikipedia.Gram positive cocci in clusters.
Staphylococcus aureus is a coccal bacterium that is Gram-positive. It is part of the natural microflora of humans and can grow on sores, pimples and other open wounds.
Staphlococcus saprphyticus is a gram positive bacteria
Would be gram-positive because of the cell wall of the Staphylococci.
E.coli is a gram negative rod mostly isolated from urine while staph is a gram positive cocci. You can differentiate them by color. E. Coli is Pink which is negative while Staph is Purple with is positive.
Gram + coccus. Positive methanol test. Yellow on agar.
Staphylococcus aureus is a Gram-positive bacteria. it has a perfect spherical cell with a diameter of one micrometer. The cell cluster looks like grapes under a microscope.

MRSA-- methicillin resistant staphylococcus aureus
MacConkey agar is designed to grow Gram-negative bacteria and also contains crystal violet dye which inhibits the growth of Gram-positive bacteria. Since S. aureus is Gram-positive it should not grow on MacConkey agar. No. MacConkey agar inhibits MOST of the Gram-positive bacteria. There are some Gram-positive bacteria that can tolerate bile-salt are able to grow in MacConkey agar. Enterococcus and some species of Staphylococcus are able to grow in MacConkey. (lack citation though)
To determine which pathogen you are dealing with. Bacteria with a thick peptidoglycan layer stain gram positive (like staphylococcus aureus) while bacteria with a thin layer stain gram negative (like escherichia coli)
No, it will not. Methylene blue agar is used to identify gram negative bacteria, staphylococcus is gram positive.
Gram positive organisms are either rods or cocci. Rods, or bacilli, include Bacillus anthracis, which causes anthrax, while cocci include Staphylococcus aureus.
S.aureus is a positive gram. Indole test is a part the biochemistry test to determinate a bacteria negative gram. indole test used to determine S.aureus, the result is negative. That is improve which S.aureus haven't trytophanase enzym (please see indole test principle)bcb
