Is staphylococcus a gram-negative or gram-positive bacterium?
Staphylococcus is a gram-positive bacterium.
What are some examples of gram positive and gram negative bacteria?
Some examples of gram-positive bacteria include Staphylococcus aureus and Streptococcus pneumoniae. Examples of gram-negative bacteria include Escherichia coli and Pseudomonas aeruginosa.
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.
What is S Acin in a urine culture report?
S Acin on a urine culture report likely refers to Staphylococcus saprophyticus, which is a type of bacteria commonly found in the gastrointestinal tract and can sometimes cause urinary tract infections in young women. It is important to consult with a healthcare provider for proper diagnosis and treatment if S. saprophyticus is identified in a urine culture.
Will staph grow on EMB agar?
Staphylococcus bacteria typically do not grow well on Eosin Methylene Blue (EMB) agar. EMB agar is selective for gram-negative bacteria, particularly Enterobacteriaceae, and contains dyes that inhibit the growth of gram-positive bacteria like Staphylococcus.
Is staphylococcus a gram-negative or gram-positive bacterium?
Staphylococcus is a gram-positive bacterium.
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
What are some examples of gram positive and gram negative bacteria?

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.
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
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.
