EMB agar preferentially selects for the growth of _________bacteria.

Question

Quizplus · Accepted Answer

EMB agar is selective for gram-negative bacteria because it contains two dyes, eosin and methylene blue, which inhibit the growth of gram-positive bacteria. Additionally, the agar is designed to differentiate between lactose fermenters and non-fermenters, which are both typically gram-negative. Gram-variable and gram-positive bacteria are not typically selected for on EMB agar.
