Descrição

Descrição geral

ReadyPlate^™ Listeria Agar plates are ready-to-use, sterile 90mm plates for the enumeration, detection, and identification of Listeria monocytogenes and other Listeria sp. from food and feeding stuff. This medium contains the chromogenic compound 5-bromo-4- chloro-3-indolyl-β-D glucopyranoside, a substrate for the detection of β-glucosidase. This enzyme is commonly produced by all Listeria sp. that appear on the medium as blue-green colored colonies. Differentiation of Listeria monocytogenes from other Listeria sp. is achieved through the production of a phosphatidylinositol-specific phospholipase C (PI-PLC). Listeria monocytogenes hydrolyses the specific purified substrate added to the medium producing an opaque halo around the colonies.
This basic pH of the medium, ensures good growth for a broad range of bacteria. The addition of inhibitors results in the reduction of the growth of the majority of concomitant Gram-positive and Gram-negative pathogens, as well as of yeasts and fungi. Selectivity is obtained by the addition of lithium chloride, nalidixic acid, and cycloheximide.
