Himedia Monsur Medium Base

Monsur Medium Base

Details

Monsur Medium Base is recommended for selective isolation and differentiation of Vibrio chlolerae and other Vibrios from pathological samples. The colonies are often surrounded by a gelatin liquefaction halo, which becomes definite and clearly visible after 48 hours incubation. Potassium tellurite reacts as both selective and differential agent. It inhibits many gram-positive bacteria. Proteus may form grey centered colonies without a halo. After 24 hours Vibrios show small translucent colonies with a grey-black center and a turbid halo, at 48 hours and longer, colonies become black centered with a well defined halo.
