MP2 Agar

Description

This cherry red, agar is prepared from a modified Columbia agar base with the addition of 5% washed bovine erythrocytes and full strength esculin.  This selective agar has been formulated to enhance the growth of gram-positive Staphylococci, Streptococci and Enterococci bacteria while inhibiting the growth of all gram- negative Enterobacteriaceae and Pseudomonas organisms. The addition of esculin enhances the capability of differentiating Streptococci.  Certain Streptococci will hydrolyze esculin, causing a mild background blackening for E-strep and a mild greening or no background coloration for suspect Streptococcus agalactiae and Streptococcus dysgalactiae organisms.  All suspect Streptococcus agalactiae organisms should be moved to our special Camp media for confirmation.
