LV002-02032
Productomschrijving
Oxoid Giolitti-Cantoni Broth, a tellurite-mannitol-glycine enrichment broth, based on the formulation of Gott and Cantoni is used for the selection and enrichment of Staphylococcus aureus from foodstuffs. Mannitol and sodium pyruvate are growth stimulants for staphylococci and aid detection of the organism when present in small numbers only.The growth of Gram-negative lactose fermenting bacilli are inhibited by lithium chloride and Gram-positive bacilli are inhibited by Potassium tellurite in combination with glycine.
The creation of anaerobic conditions by overlaying with 2cm of sterile paraffin wax inhibits the growth of micrococci.
Giolitti-Cantoni Broth is recommended for the detection of Staphylococcus aureus in dried baby milk and other weaning foods where the organism should be absent from 1g of test material.
The medium is suitable for the examination of meat and meat products. For this purpose the concentration of the Potassium tellurite must be reduced to 0.35% and it is recommended that the weight of the test sample should be reduced to 0.1-0.01g.
