this MacConkey with crystal violet can grow enterococcus
MacConkey agar is designed to grow Gram-negative bacteria and also contains crystal violet dye which inhibits the growth of Gram-positive bacteria. Since S. aureus is Gram-positive it should not grow on MacConkey agar. No. MacConkey agar inhibits MOST of the Gram-positive bacteria. There are some Gram-positive bacteria that can tolerate bile-salt are able to grow in MacConkey agar. Enterococcus and some species of Staphylococcus are able to grow in MacConkey.

E.coli shows pink colour colonies in MacConkey agar due to fermentation of lactose
types macconkey agar
Yes. But because it is not a lactose fermenter, the colonies will be colorless (or sometimes have a green tint).

MacConkey agar
yes
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.

campylobacter can growth in mcconkey agar.
MacConkey's agar refers to a culture medium that is designed to selectively grow Gram-negative bacteria. It contains crystal violet dye, which inhibits certain Gram-positive bacteria.
The organism would be expected to grow better in nutrient agar. Nutrient agar is rich in nutrients and microorganisms grow well when there is availability of nutrients.

Yes. But because it is not a lactose fermenter, the colonies will be colorless (or sometimes have a green tint).
