Remel™ Casman Agar Base

Isolate wide variety of microorganisms using Thermo Scientific™ Remel™ Casman Agar Base (Dehydrate). This medium was developed to substitute previous formulations that required fresh and heated blood and fresh meat infusions to supply nutrients necessary for the growth of Haemophilus and gonococci^1,2. Following a study of several dehydrated blood agar bases, Leopold selected Casman Agar for routine use in the isolation of bacteria from clinical specimens³.

This medium contains peptones and beef extract which provide amino acids and other nitrogenous compounds necessary for the growth of bacteria. Dextrose added in the medium enhances the growth of pathogenic cocci. Nicotinamide inhibits the enzyme activity of erythrocytes that destroys the V factor in blood. Cornstarch serves to neutralize toxic fatty acids, which inhibit the growth of some fastidious bacteria and enhance beta hemolytic reactions. The growth factors required by Haemophilus spp., hemin (X factor) and nicotinamide adenine dinucleotide (V factor) are supplied by sheep blood.
