Selectively enrich Saphylococcus aureus from food and feedstuffs when following ISO 6888-3:2003 with Thermo Scientific™ Oxoid™ Giolitti-Cantoni Broth (Dehydrated) when used with sterile solution of Potassium tellurite (SR0030). Mannitol and sodium pyruvate in the medium act as growth stimulants for staphylococci and aid detection of the organisms when present in small numbers1.

The growth of Gram-negative lactose-fermenting bacilli is inhibited by lithium chloride and Gram-positive bacilli are inhibited by potassium tellurite in combination with glycine.
