- W4253236463 abstract "Abstract Background: At present, the process of inspection and quarantine starts with sampling at the customs port, continues with transporting the samples to the central laboratory for inspection experiments, and ends with the inspected results being fed back to the port. This process takes a rather long time, has the risks of degradation of biological samples and generation of pathogenic microorganisms, and does not meet the rapid on-site detection demand. Therefore, development of a technology for rapid and high-throughput detection of pathogenic microorganisms at the customs port is of great significance. This study was to develop a microfluidic chip to be applied to rapid high-throughput detection for swine disease with higher accuracy and lower risk of spreading pathogenic microorganisms during transportation. Results: PCR technology has the advantages of high accurate and sensitivity in disease detection, clinical testing and food quarantine, so it plays an important role in customs inspection. However, the traditional PCR detection instrument has a large size, is time-consuming and has strict requirements on the experimental environment, which greatly limit its application in on-site testing. In this paper, the positive nucleic acid of four swine diseases were detected by a portable and rapid microfluidic PCR system, which could achieve a on-site real-time quantitative PCR detection. Eight clinical samples were detected together on the microfluidic chip in the system, and the detection results were obtained in about an hour. The detection limit of this microfluidic PCR detection system was as low as 1 copies/μL. The results show that the high sensitivity and specificity of the microfluidic PCR detection system in disease detection will play an important role in customs inspection and quarantine during customs clearance. Conclusion: The microfluidic PCR detection system established in this study could meet the requirements for rapid detection of samples at the customs port The new method can avoid the risky process of transporting the samples from the sampling site to the testing lab, and drastically reducing the inspection cycle, and would enable parallel inspections on one chip which greatly raising the efficiency of inspection." @default.
