一般描述
Universal Pre-enrichment Broth (UPB) is used for recovering sublethally injured Salmonella and Listeria from food products. UPB lacks inhibitory agents to provide selectivity for target pathogens and may not be adapted for samples with high levels of background microflora.
应用
Universal Pre-enrichment Broth (UPB) has been used in the enrichment of Listeria monocytogenes and Salmonella species. It has also been used in the growth kinetic studies of Salmonella typhimurium.
制备说明
Suspend 38.05 grams in 1000 ml distilled water. Heat if necessary, to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Mix well and dispense as desired.
附注
We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.

This study rigorously evaluated a previously developed immunobead array method to simultaneously detect three important foodborne pathogens, Campylobacter jejuni, Listeria monocytogenes, and Salmonella spp., for its actual application in routine food testing. Due to the limitation of the detection limit
