Description

The primer pair of echinococcosis cause of disease is organized to combine and kit with surveyor for detecting
Technical field
The invention belongs to medical diagnosis on disease field, and in particular to one kind is used to detecting and identifying that a variety of people organize echinococcosis cause of disease Primer pair combination and its kit.
Background technology
Echinococcosis (Hydatidosis) is being commonly called as hydatidosis (echinococcosis), is the children by echinococcus Worm parasitizes parasitic zoonoses caused by human body.The Echinococcus that the whole world was found in the past is divided into 6 kinds, i.e., Echinococcus granulosus (Echinococcus granulosus), Echinococcus multilocularis (Echinococcus Multilocularis), Fu Shi echinococcus (Echinococcus vogeli), less section echinococcus (Echinococcus Oligarthus), Echinococcus felids and Shiqu echinococcus (Echinococcus shiquicus), wherein carefully Grain echinococcus (E.granulosus) is divided into 10 genotype, i.e. Echinococcus granulosus G1-G10 types by genotype.With point Application and development of the sub- biology techniques in echinococcus is studied, the result that people obtain according to Phylogenetic analysis, again 10 genotype of original Echinococcus granulosus (E.granulosus) are divided into 4 new worm kinds, they are respectively E.granulosus sensu stricto (G1-G3 types), E.equinus (G4), E.ortleppi (G5) and E.canadensis(G6–G10).Echinococcosis is widely current in all over the world, falls ill to have over nearly 20 years and increases trend.China is complete The popular the most serious country of ball echinococcosis, district occurred frequently accounts for the 44% of national total area, and compromised population exceedes 5,000,000.
According to existing literature, what China had now been found that causes the echinococcosis cause of disease of human infection to have three kinds, wherein, carefully In the highest flight, Echinococcus granulosus G6-G10 types are in various regions for grain echinococcus G1-G3 types and the prevalence of Echinococcus multilocularis Show distributed state, but its infection risk also can not be ignored.The adult and its larva of echinococcus not of the same race are in form, biology Feature, pathogenic aspect have differences.Wherein, the children of Echinococcus granulosus G1-G3 types and Echinococcus granulosus G6-G10 types Worm can cause the cystic echinococcosis of people, and the larva of Echinococcus multilocularis can cause the alveolar echinococcosis of people.Cystic echinococcosis can be sent out Life is in the multiple internal organs of whole body, and the most common with liver, lung, alveolar echinococcosis primary lesion is nearly all located at liver.Detection and identification The species pop disease of echinococcosis cause of disease is learned research, the prevention and control of disease and treatment and all had great importance.
At present, existing PCR detection method by specific amplification it is minimally invasive/operation patients lesion tissue in target DNA sequence, To be confirmed whether to infect echinococcosis, and confirm the echinococcosis cause of disease species of infection.Existing PCR detection method mainly has substance PCR method and multiple PCR method.(the A PCR system for identification of such as Dinkel A Echinococcus species and genotypes,with reference to the epidemiological situation in eastern Africa[J].2004:48-48.) establish the PCR detection sides of detection Echinococcus granulosus Method;(the Development of Three PCR Assays for the Differentiation such as Boufana B between Echinococcus shiquicus,E.granulosus(G1genotype),and E.multilocularis DNA in the Co-Endemic Region of Qinghai-Tibet plateau,China[J].American Journal of Tropical Medicine&Hygiene,2013,88(4):795-802) establish detection particulate spine ball silk ribbon Worm G1 types, Echinococcus multilocularis and 3 kinds of substance PCR methods of Shiqu echinococcus;(the Detection of such as Can H Echinococcus granulosus and Echinococcus multilocularis in cyst samples using a novel single tube multiplex real-time polymerase chain reaction.[J] .Mikrobiyoloji Bulteni,2016,50(2):266.) establish while detecting Echinococcus multilocularis and particulate spine ball silk ribbon The real-time fluorescence multiple PCR method of worm;Cong nuan Liu et al. (Discrimination between E.granulosus sensu stricto,E.multilocularis and E.shiquicus Using a Multiplex PCR Assay. [J].Plos Neglected Tropical Diseases,2015,9(9):) and Lou Zhongzi et al. (patent e0004084. CN201310102181.4) establish while detecting Echinococcus granulosus G1-G3 types, Shiqu echinococcus and Echinococcus multilocularis Multiple PCR method, wherein Shiqu echinococcus do not find human infection also at present, and its infection host is mainly Xiaoxinganling mountains Animal and canid.
In the above method, one reaction system of substance PCR method can only detect a kind of cause of disease, and detection program is cumbersome, time-consuming Arduously, it is unfavorable for the quick detection of extensive sample.Multiple PCR method can be to two under same system, same reaction condition Or more than two different target genes synchronize the reaction system of detection, i.e., one can detect a variety of cause of diseases simultaneously, greatly improve The efficiency of method.But, three-type-person's echinococcosis disease that on the one hand existing multiple PCR method not finds directed entirely to China Original (Echinococcus granulosus G1-G3 type E.granulosus sensu stricto, Echinococcus multilocularis E.Multilocularis With Echinococcus granulosus G6-G10 type E.canadensis) and design, it is impossible to meet detection and identify Human Hydatidosis cause of disease Demand;On the other hand, the design of primers difficulty of multiplex PCR is far longer than substance PCR, because adding multipair draw in one system Thing, easily occurs cross reaction with the nearer cause of disease of affiliation, occurs that complementation also easily occurs between false positive results, and primer pair With reference to, be also easy to produce disturbing reaction, therefore, existing echinococcosis multiple PCR method has that specific poor, method is unreliable etc. to ask Topic.
Therefore, the present invention is directed to Echinococcus granulosus G1-G3 types (the E.granulosus sensu of China's human infection Stricto), Echinococcus multilocularis (E.Multilocularis) and Echinococcus granulosus G6-G10 types (E.canadensis) three The chondriogen conservative region design specific primer of kind of cause of disease, constructing a kind of can synchronously detect a variety of echinococcosis cause of diseases Multiple PCR method.This method high specificity, sensitivity are high, and with high flux, simplicity, quick advantage, can significantly improve Operating efficiency, reduces time, financial cost, in the further identification parting and echinococcosis disease of minimally invasive or operation echinococcosis patient People's Molecule Epidemiology Investigation field is with a wide range of applications.
