An ultra-fast, one-step RNA amplification method for the detection of <i>Salmonella</i> in seafood

One of the most damaging pathogens of pinewood is the pinewood nematode (PWN), Bursaphelenchus xylophilus, which could cause an adverse effect on the ecosystems of forests and the commerce of timber. Therefore, it is crucial to realize rapid and accurate B. xylophilus detection. In this work, an accelerated strand exchange amplification method (ASEA) was established to detect B. xylophilus for the first time. By integrating with fast nucleic acid extraction, the whole detection procedure could be finished within 30 min, dramatically shortened the detection time. The ASEA method exhibited high specificity toward B. xylophilus and the detection limit for B. xylophilus plasmid DNA was as low as 1.0 × 100 copies/μL. Furthermore, the ASEA approach also exhibited accurate detection for B. xylophilus when applied to actual pinewood samples, meeting the demand of B. xylophilus detection in realistic scenario. We believe the ASEA method has significant potential for B. xylophilus detection, and it will be helpful for controlling forest pest and quarantine regulations.This article is protected by copyright.
