Stool screening test

Hardy Diagnostics introduces EnteroScreen 4™ for a single tube screen on stool specimens for enteric pathogens. It is designed to rule out normal enteric flora and to aid in the detection and the differentiation of Salmonella and Shigella species.

EnteroScreen 4™ eliminates the need to inoculate the three to four tubes.

The EnteroScreen 4™ system consists of four layers in a single tube; three agar layers and petrolatum layer. The tube contains, in order from bottom to top, urea agar, petrolatum plug, modified lysine iron agar and lysine iron agar.

With this method, urease activity, lysine decarboxylase, lysine deaminase, gas and hydrogen sulfide production reactions can be simultaneously evaluated. Urea agar, the bottom agar layer, is added to the tube to differentiate other nonlactose-fermenters, from Salmonella and Shigella species. Technical insert comes with an easy-to-follow identification algorithm in a flow-chart format.
