PDX-LIB – Listeria Indicator Broth

Call for Price

Paradigm Diagnostics' Listeria indicator broth (PDX-LIB) is intended to be used in the food processing environment and on food contact surfaces to detect the presence of Listeria species. A color change from yellow to light brown/black is considered presumptive positive. Applicability of PDX-LIB is limited for selected common Listeria species (Listeria monocytogenes, L. innocua, L. ivanovii, and L. welshmeri) on selected common surface types (Sealed concrete, ceramic tile, stainless steel, and plastic).

Description

Scientific Principal
PDX-LIB contains a patented formula of antibiotics, growth enhancers and color- changing compounds. The antibiotics function synergistically to inhibit most non-Listeria microorganisms. Growth enhancers provide recovery nutrients to support the growth of sub-lethally injured Listeria. Indicator compounds will turn the broth from yellow to black when converted by beta-glucosidase enzyme produced by Listeria species. A brown to black color 30-48 hours at 37oC indicates a presumptive positive test for Listeria spp. Positive results can be read as early as 30 hours. Results cannot be considered negative until samples have been incubated for 48 hours.
