- Abstract
[Objective] To establish a simple, rapid and visual pathogen detection method for shrimp, and to achieve self detection by fishermen. [Method]The specific primers of LAMP (loop-mediated isothermal amplification technique) were designed for decapod iridescent virus 1 (DIV1). After optimizing the conditions of reagent dosage, temperature and reaction time, a visual and rapid detection method of LAMP combined with hydroxynaphthol blue (HNB) was established. [Result] 12 mmol/ L Mg2+ and 250 μmol/ L HNB solution in the LAMP reaction system was the most suitable condition at 65 ℃ for 60 min. The minimum detection limits of LAMP-HNB of DIV1 was 10² copies/ μL plasmid. The stability and specificity of the detection of DIV1 had also been verified using positive plasmids with target genes, and the results of 16 repeated experiments were relatively stable, multiple template amplification experiments did not show false positives, which meets the experimental requirements. [Conclusion] The LAMP-HNB visualization rapid detection method established in this study is suitable for the on-site rapid detection of shrimp DIV1 mentioned above. [ABSTRACT FROM AUTHOR]
