MRSA (Methicillin-resistant Staphylococcus aureus) is not classified as selective or differential; rather, it refers to a specific strain of Staphylococcus aureus resistant to methicillin and other antibiotics. However, MRSA can be identified using selective media that inhibit the growth of non-MRSA strains while allowing MRSA to grow, such as mannitol salt agar with specific antibiotics. In this context, it can be considered selective for isolating MRSA from samples.
What else can I help you with?
Is a tsa agar selective or differential?
its a selective media
Is chromagar a selective agar?
It is selective and differential. There are many different CHROMagar varieties. CHROMagar MRSA II, for example, will select for Staphylococcus aureusand MRSA colonies will turn purple. Other strains will be different colors. Many people dispute the results and the companies do not suggest that it be used for diagnosis.
Is tryptone broth differential or selective media?
Tryptone broth is neither differential nor selective media. It is a nutrient-rich medium used for the growth of a wide range of microorganisms.
Is Mannitol salt agar a selective or a differential medium?
Both
Is the media for oxidase test selective or differential?
The media for oxidase test is differential, not selective. It helps differentiate between bacteria that produce the enzyme cytochrome c oxidase (positive result) and those that do not (negative result).
Why can mannitol salt agar and EMB agar be described as both selective and differential media?
it is selective because only a salt tolerant can grow. 7.5 nacl it has diffrential properties also. if mannitol formentors turns yellow staphlococus aureus; but if it has no change then its a nonpathogenic staphlococci (s. edermis)
What is blood agar tellurite medium?
It is a SELECTIVE DIFFERENTIAL media used for the groth of Corynebacterium diphtheria.
Minimal salt agar that contains detergent as a carbon source is selective or differential?
The minimal salt agar with detergent as a carbon source would be considered selective. The detergent would inhibit the growth of organisms unable to tolerate or metabolize it, allowing only detergent-resistant microorganisms to grow.
Is TSA selective or differential media?
Selective media favor the growth of particular microorganisms. Bile salt or dye like basic fuschin and crystal violet favor the growth of gram-negative bacteria by inhibiting the growth of gram positive bacteria. Maconkey agar is widely used to grow E.coli and related bacteria. Differential media are media that distinguish among different groups of microbes and even permit tentative identification of microorganisms based on their biological characterstics. Blood agar is used to culture of bacteria from human throat. Mckoney agar is both differential and selective media.
How could the use of a medium which is both selective and differential be justified?
The use of a medium that is both selective and differential can be justified in a few ways. They allowe the growth of organisms that can be of interest. The media can also be quite useful diagnostically in medical settings.
Why cant you use the same selective and differential media for staphylococci and streptococci?
Staphylococci and Streptococci grow in different locations under different conditions. Staphylococci are found on skin surfaces and nasal path whereas Sptreptococci are found in the intestinal and urinary tract. Thus, due to difference in the growth conditions and biochemical processes, we need to use different selective and differential media for them.Binod,Toronto, Canada
What is septic MRSA?
Septic (sepsis) MRSA means that the MRSA bacteria has entered into the blood.
