The triose phosphate isomerase (TPI) gene of Giardia lamblia was selected as the target gene, for which primers were designed, and the synthetic plasmid containing TPI gene sequence was used as the template to establish a LAMP microfluidic chip detection method for detection ofG. lamblia. The specificity, sensitivity, repeatability and stability of the method were evaluated. The results showed that the established LAMP microfluidic chip detection method for G. lamblia could complete nucleic acid amplification within 30 min, and the detection sensitivity reached 4.0 × 10 copies/μl and 0.01 ng nucleic acid/μl. In addition, this method showed high specificity for G. lamblia, while not being able to amplify the nucleic acids of Cryptosporidium, Trichinella spiralis, Eimeria, hepatitis E virus or Enterococcus faecalis. The stability and repeatability of the method were tested using different dilutions of recombinant plasmids. The results showed that the nucleic acid concentration was highly correlated with the reaction time, and positive fecal samples presented amplifying signals. The results demonstrate the establishment of a lamp microfluidic chip-based nucleic acid detection method forG. lamblia. The method is simple and highly specific.
Key words： Giardia lamblia; Microfluidic chip; LAMP; TPI gene
