Question

does e coli grow on mannitol salt agar

Answer ( 1 )

  1. No, Escherichia coli (E. coli) does not grow on Mannitol Salt Agar (MSA). Mannitol Salt Agar is a selective and differential agar primarily used for the isolation and differentiation of Staphylococcus species, particularly Staphylococcus aureus. E. coli, being a coliform bacterium, does not possess the ability to ferment mannitol or tolerate the high salt concentration present in MSA, so it typically does not grow on this medium.
