Abstract:
Objective To establish a simple and rapid detection technique for Oncomelania infected with Schistosoma japonicum(SJ), with high sensitivity and good specificity .Methods The gene fragment of SJ was amplified by PCR , and cloned into the T-vector to construct positive-reference.An isothermal nucleic acid amplification reaction system for detecting Oncomelania infected with SJ was set up , and its sensitivity was analyzed by detecting positive-reference diluted according to geometric proportion , and its specificity by detecting the genomic DNA of relative samples .Then, a corresponding means of purifying nucleic acid was designed to assemble a reagent detecting Oncomelania infected with SJ . This reagent was validated by detecting Oncomelania samples.Results The 213 bp amplified products were obtained and used to construct recombination T-vector for positive reference .An isothermal nucleic acid amplification reaction system was set up for detecting Oncomelania infected with SJ , and the amplification results could be simply determined by color change, with better sensitivity and specificity .The reagents for detecting Oncomelania infected with SJ were assembled , which could detect samples containing only 1% infected Oncomelania.Conclusion A visible detection method for Oncomelania infected with SJ is successfully established and validated .
