Yes. Staphylococci are classified as gram positive bacteria and appear as purple spheres when Gram stained.

Which bacilli are gram positive oxidase negative and catalase positive?
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer. For gram negative, catalase negative and oxidase negative rods, it is likely that you have bacteria of the Bacteroides genus.
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.
Will staph grow on EMB agar?
No, it will not. Methylene blue agar is used to identify gram negative bacteria, staphylococcus is gram positive.
What is the color of staphylococcus aureus after gram staining?
Post ID Special:Contributionssaid: "blue-violet.....because it is a gram-negative bacteria"Wrong...the color is correct, but S. aureus is gram-POSITIVE.
On the basis of gram reaction only can you distinguish between staphylococcus and streptococcus?
If the Gram stain is properly done, and based on color alone: - you CANNOT distinguish between Staphylococcus (positive/purple) and Streptococcus (positive/purple) - you CAN distinguish between Staphylococcus (positive/purple) and Neisseria (negative/red) - you CANNOT distinguish between Escherichia (negative/red) and Proteus (negative/red) - you CAN distinguish between Escherichia (negative/red) and Bacillus (positive/purple) Gram positives will stain purple because of the retention of the dye (crystal violet) in their thick peptidoglycan cell walls. On the other hand, Gram negatives have a thin cell wall and cannot retain the purple stain, so when they are counterstained, they will appear red
Is staphylococcus epidermitis gram positive or negative?
Gram positive.
Is staphylococcus arueus of upper resp gram positive or gram negative?
S. arureus is a gram posotive cocciScientific classificationDomain:BacteriaKingdom:EubacteriaPhylum:FirmicutesClass:BacilliOrder:BacillalesFamily:StaphylococcaceaeGenus:StaphylococcusSpecies:S. aureus
Staphylococcus?
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
What does not belong with the others bacillus escerichia lactobacillus staphylococcus streptococcus?
Escherichia does not belong...bacteria of this Genus are Gram negative, the rest are Gram positive bacteria.

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.
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.
Is impetigo gram positive rods?
No. Impetigo is usually caused by Staphylococcus aureus, gram positive cocci.
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.
Will staph grow on EMB agar?
No, it will not. Methylene blue agar is used to identify gram negative bacteria, staphylococcus is gram positive.
What is the color of staphylococcus aureus after gram staining?
Post ID Special:Contributionssaid: "blue-violet.....because it is a gram-negative bacteria"Wrong...the color is correct, but S. aureus is gram-POSITIVE.
