Embodiment 1

[0051] 1. Sample source

[0052] 360 double-umbilical snails were collected from Shenzhen, Guangdong (170), Dongguan, Guangdong (109), and Hong Kong (81).

[0053] 2. DNA extraction

[0054] Genomic DNA was extracted from the samples of the umbilical snail, quantified by a spectrophotometer, and checked by agarose gel electrophoresis. Genomic DNA concentration>10ng / μL, OD 260 / OD 280 >1.7, take samples with bright and clear electrophoresis strips without drag for subsequent operations. The sample DNA that passed the quality inspection was diluted with deionized water to a concentration of 20 ng / μL, transferred to a 384-well plate, and stored at -20°C for later use.

Abstract

The invention discloses an SNP (single nucleotide polymorphism) marker for geospecific biomphalaria tracing and a detection method and application of the SNP marker. The SNP marker comprises at leastone of three SNP molecular marker bodies, namely SNPs of the 501st position in the SEQ ID NO:1, the 501st position in the SEQ ID NO:2 or the 501st position in the SEQ ID NO:3. The detection method includes: extracting a biomphalaria sample DNA; performing PCR (polymerase chain reaction) amplification and single base extension on target genes of sample DNA to form sample analytes; performing cocrystallization of sample analytes and matrixes of mass spectrometry chips and detecting the SNPs of the target genes to achieve precise typing of the different SNPs. By the above method, SNP typing information of the different positions can be acquired rapidly and accurately, and reliable reference information is provided for subsequent correlation research. The biomphalaria from the different areascan be distinguished according to the SNP chips of the positions, and rapid tracing detection is realized.

Description

technical field [0001] The invention belongs to the technical field of molecular biology, and more specifically relates to a SNP marker, a detection method and an application for traceability of geographically specific umbilical snails. Background technique [0002] Double-umbilical snails belong to the phylum Molluscs, Pneumonia subclass, and Snail family. Among the more than 30 known species of double-umbilical snails, double-umbilical snails smooth, double-umbilical snails, shoal double-umbilical snails, and Puer's double-umbilical snails 18 species including S. mansoni and other 18 species can act as intermediate hosts of Schistosoma mansoni to spread schistosomiasis, causing serious disease burden to the world, especially in Africa, South America, Asia and other regions, and seriously hindering social and economic development. Among them, the double umbilical snails are mainly distributed in the fresh waters of St. Lucie in the Caribbean Sea and the northeastern coast o...
