Super-Fast Detection of Bacillus cereus by Combining Cellulose Filter Paper-Based DNA Extraction, Multienzyme Isothermal Rapid Amplification, and Lateral Flow Dipstick (MIRA-LFD).

ABSTRACT: Bacillus cereus is a widespread foodborne pathogen that can cause food poisoning when present in food at certain levels. Ingesting contaminated food may lead to symptoms such as abdominal pain, diarrhea, and, in severe cases, life-threatening conditions. In this study, a simple and super-fast method for detecting B. cereus was developed, which combines cellulose filter paper-based DNA extraction, multienzyme isothermal rapid amplification (MIRA), and lateral flow dipstick (LFD) technology. Initially, PCR was adopted to evaluate the DNA extraction efficiency of the filter paper, followed by the optimization of the lysis formula and extraction conditions. With the above optimization, DNA that can be used for subsequent nucleic acid amplification can be obtained within 3 min. Th
