GELATIN MANNITOL SALT AGAR (STAPHYLOCOCCUS AGAR NO. 110)

Staphylococci are widespread in nature though they are mainly found living on the skin, skin glands and mucous membrane of mammals and birds. These organisms are also associated with staphylococcal food poisoning. Staphylococcus Agar No. 110 also known as Stone Gelatin Agar is used for the selective isolation of pathogenic Staphylococci on the basis of pigment production, mannitol fermentation and gelatin liquefaction. These properties are few of the characteristics of pathogenic Staphylococci.
Staphylococcus Agar No. 110 is recommended by APHA and AOAC. The medium can be used with Egg Yolk Emulsion to study the egg yolk reactions.
