Product Summary and Explanation
In 1911, Russell described the use of two sugars in a medium to differentiate Gram-negative organisms of intestinal origin. Lead or iron salts were added to Russell’s medium to detect the presence of hydrogen sulfide. Kligler added lead acetate to Russell Double Sugar Agar, resulting in a medium capable of differentiating typhoid, paratyphoid, and dysentery. A modification of this medium was developed, Kligler Iron Agar, using Phenol Red as an indicator and iron salts to detect hydrogen sulfide production. In 1940, Sulkin and Willett described a triple sugar ferrous sulfate medium for use in identification of enteric organisms. Triple Sugar Iron Agar is essentially the formula originally described by Sulkin and Willett.
Triple Sugar Iron Agar is recommended for differentiation of enteric, Gram-negative bacilli from clinical specimens, dairy samples, and food products.
