Rapid identification of listeria spp. without enrichment broth
A recently granted patent (Publication Number: US11905566B2) discloses a composition for nucleic acid amplification assays and lysis reagent solutions. The composition includes a lysis reagent solution containing specific components such as sodium sulfate, magnesium sulfate, poly(ethylene oxide)octylphenyl ether, potassium phosphate, lysozyme, and proteinase K. Additionally, the composition comprises an isothermal nucleic acid amplification assay involving a polymerase, two template nucleic acids, and a nicking enzyme. Importantly, the composition does not include enrichment broth, distinguishing it from conventional methods.
Furthermore, the patent claims a composition that includes the same lysis reagent solution along with a sample of Listeria, without the presence of enrichment broth. This composition can also incorporate an isothermal nucleic acid amplification assay involving a polymerase, two template nucleic acids, and a nicking enzyme. The patent specifies that the sample in this composition can be an environmental sample, collected using a collection device pre-moistened with letheen broth. These claims highlight the innovative approach of the composition in streamlining nucleic acid amplification assays for efficient and accurate detection of target nucleotide sequences, particularly in environmental samples.
