Hektoen Enteric Agar, Granulated 500G

This granulated medium is used for differential and selective isolation of Salmonella and Shigella species from enteric pathological specimens. It is currently recommended as one of several plating media for the culture of Enterobacteriaceae from stool specimens. The increased concentration of carbohydrate and proteose peptone helps to reduce the inhibitory effect of bile salts and indicators and allows good growth of Salmonella and Shigella species while inhibiting the normal intestinal flora.
