Will s aureus grow on a crystal violet agar plate?
Staphylococcus aureus can grow on crystal violet agar plates as crystal violet agar is a selective medium that inhibits the growth of Gram-negative bacteria and allows the growth of Gram-positive bacteria like S. aureus.
Does Staphylococcus grow on non crystal violet MacConkey agar?
Staphylococcus will not grow on Mac since crystal violet inhibits the growth of Gram positivesfmchinea: Actually some species of staphylococcus grow on MacConkey's plate including Staphylococcus aureus.
What are the colonial features of staphylococus aureus in nutrient agar?
* Colonies are circular, 2-3 nm in diameter with a smooth shiny surface when grown on nutrient agar,milk agar or blood agar for 24 h at 37 degrees * Colonies are often pigmented,though a few strains are unpigmented Got the answers from here http://www.geocities.com/SouthBeach/Port/3008/staphyl.html
If an organism can grow on both a nutrient agar and a MacConkey Agar on which would you expect it to grow better?
You would expect the organism to grow better on nutrient agar because it is a general-purpose medium that supports the growth of a wide range of organisms. MacConkey agar, on the other hand, contains inhibitors that selectively inhibit the growth of Gram-negative bacteria, so the organism may not grow as well on this medium.
What are non fastidious microorganisms?
Fastidious organisms are bacteria that can't produce their own vitamins, so they usually acquire them from the host. They require special fortified agar to be grown in the laboratory. I assume non-fastidious organisms can produce their own nutrients and don't need the special agar! Hope that helps

Why staph aureus grows on macconkey agar?
Staphylococcus aureus does not typically grow on MacConkey agar, as this medium is selective for Gram-negative bacteria, particularly Enterobacteriaceae, due to its bile salts and crystal violet dye that inhibit Gram-positive organisms. However, if S. aureus is observed on MacConkey agar, it may be due to contamination or the presence of certain strains that can tolerate the inhibitory conditions. Generally, for the isolation of S. aureus, media such as mannitol salt agar is more appropriate since it is selective for staphylococci.
Can Staphylococcus grow in penicillin G?
It depends. Some bacteria, like Staphylococcus aureus, have become resistant to penicillin G. Not all species of Staphylococcus are resistant. Even some strains of Staphylococcus aureus are still susceptible to penicillin G.
How do mannitol-salt agar tests work?
Mannitol salt agar supports growth of organisms that can grow in a high salt concentration, particularly Staphylococcus species and halophiles. The phenol red pH indicator in the agar will also let you know whether or not the bacterium you streaked ferments mannitol by changing to a yellow color if fermentation has occured.

What is the aerotolerance of staphylococcus aureus?
Staphylococcus aureus is facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It can tolerate oxygen but thrives better in environments with low to moderate oxygen levels.
Can vibrio parahaemolyticus grow on nutrient agar?
Yes, Vibrio parahaemolyticus can grow on nutrient agar, as it is a common medium used for culturing a wide variety of bacteria. Nutrient agar provides the necessary nutrients for the growth of many bacterial species, including Vibrio parahaemolyticus.
What agar does Corynebacterium xerosis grow on?
Corynebacterium xerosis typically grows on nutrient agar.
Is MRSA selective or differential?
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.
Is MRSA virus reproductive?
MRSA is a bacterium, (methicillin-resistant staphylococcus aureus), not a virus. It does grow, but not like a virus.
