09/02/2021 ÿú Staphylococci are very hardy and will grow on nutrient agar: S. aureus can grow at temperature! Medium mannitol-salt agar (MSA Difco) medium from red to yellow isolated on Baird-Parker agar must confirmed. Colonies are often pigmented, though a.
30/03/2021 ÿú Will Staphylococcus aureus grow on nutrient agar? Staphylococci can be isolated in routinely used bacteriological media like nutrient agar, blood agar or specific media like mannitol salt agar (MSA), lipovitellin salt mannitol agar (LSM), Vogel-Johnson agar (VJ), Baird Parker agar, potassium thiocyanate-actidione-sodium azide-egg yolk-pyruvate agar (KRANEP).
Tellurite and lithium chloride in Baird-Parker agar inhibit the growth of most bacteria, while pyruvate and glycine specifically promote the growth of S. aureus. Tryptic soy broth (TSB) and BHI are the preferred media to grow cultures of Staphylococci. Cultures are grown at 37øC with aeration.

What are the reasons as to why Staphylococcus aureus does not grow on MacConkey agar? S. aureus is Gram positive - which crystal violet (that is part of MacConkey) will inhibit. S. aureus is also inhibited by the bile salts that is part of the agar (since the bile salts will limit growth to enteric bacteria), Staphylococcus aureus easily grow on Blood agar, Brain Heart Infusion agar then you can grow it on Manitol salt agar and identification using catalase and coagulase and vitek2 Best regrades.
10/04/2009 ÿú Staphylococcus can grow well on mannitol salt agar because it can tolerate high saline. It prefers to grown on a salty or saline medium in order to grow at all.;"
