Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories reflect big differences in the microbes' biology, and they also dictate ...

This medium is both selective and differential. The selective ingredients are the bile salts and the dye, crystal violet which inhibit the growth of Gram-positive bacteria. The differential ingredient ...

Three of these six pathogens are antibiotic-resistant Gram-negative bacteria. Recently, antibacterial drugs against ESBL-producing Gram-negative bacteria accounted for ∼15% (2 out of 13 ...

The selective components are the eosin and methylene blue dyes that inhibit the growth of Gram-positive bacteria and permit the growth of Gram-negative enteric rods. The differential component of the ...
