The selectivity of the medium is due to Lithium Chloride and a 1% Potassium Tellurite Solution, suppressing growth of organisms other than staphylococci.
no
Minimal salts agar is selective and differential. It grows gram positive bacteria and turns different color depending on what the specimen is.

Peptone glucose agar (PGA) medium
Gram + bacteria do NOT grow on EMB agar, EMB agar inhibits their growth, and is selective for Gram -
Baird Parker agar is used for selecive isolisation of gram positive Staphylococci species. It was introduced to overcome the problems with recovering damaged S. aureus from foodstuffs.
its a selective media
Selective
Glucose Salts Agar (GSA) is a selective agar that selects for gram-negative bacteria only. This means that no gram-positive bacteria will be able to grow on it.
no
Potassium tellurite agar is selective for the growth of Staphylococci and is somewhat selective for the growth of Corynebacteria. Staphylococci and Corynebacteria reduce the potassium tellurite in the agar, which makes the colonies grow black.
Salmonella-Shigella (SS) agar. XLD agar. Hekton enteric agar.
Because 7.5% NaCl agar inhibits gram negative organisms from growing, and is "selective" in that only gram positive organisms can grow in this type of agar.

thermus agar
Minimal salts agar is selective and differential. It grows gram positive bacteria and turns different color depending on what the specimen is.
