DNAFoil, a novel technology for the rapid detection of food pathogens: Preliminary validation on Salmonella and Listeria monocytogenes

نویسندگان

چکیده

Over the past decades, several tools have been developed for food pathogen detection, including proteomics, metabolomics, immunological, biosensor, and nucleic acid-based approaches. Although these techniques are reliable precise, they time-consuming, technically challenging, costly. Hence, it is necessary to develop rapid which can be performed at household level. DNAFoil mechanism a portable, completely self-administered, on-site DNA test that does not need expensive instru-ments or settings confirm detection in as little 30 min. was used successfully detecting contamination adulteration with pork derivatives (down 0.1%) vegetal components 0.01%), respectively. In this study, initial validation experiments of were investigated detect Listeria monocytogenes Salmonella contamination. To specificity proposed method toward Salmonella, 18 different strains, 6 non-Salmonella bacteria, 2 fungi investigated; also, case monocytogenes, five bacterial two fungi, investigated. The results stated Swiss Decode L. solutions few 1 10 copies per microliter, also showed accuracy our ranges between 92 100%, while precision value ranged 88 100%. terms quality control applicability, reactions could visually detected naked eye using lateral flow strip, in-place during manufacturing more lab tests. cost, usually much cheaper than traditional methods. Therefore, promising universal technology pathogens.

Rapid Detection of Listeria monocytogenes in Food and Food Animals

The objective of this study was to streamline the detection and identification of Listeria monocytogenes (LM) in livestock and foods. Hog tonsil scrapings, hog tissues collected at necropsy, ground pork, and turkey washes were inoculated into UVM-1 (10% w/v) and after incubation (3 days) transferred to UVM-2. After 2 days, samples were plated to Palcam agar and incubated (48 h, 37 o C). Charact...

Fluorescence-Free Biosensor Methods in Detection of Food Pathogens with a Special Focus on Listeria monocytogenes

Food pathogens contaminate food products that allow their growth on the shelf and also under refrigerated conditions. Therefore, it is of utmost importance to lower the limit of detection (LOD) of the method used and to obtain the results within hours to few days. Biosensor methods exploit the available technologies to individuate and provide an approximate quantification of the bacteria presen...
