Description
Technical field
The present invention relates to a kind of primer pair and the test kit that detect zooparasite.Exactly, the present invention relates to a kind of primer and the detection kit of distinguishing detection low pathogenicity and highly pathogenic babesia motasi.
Background technology
The Babesia now reported has more than 100 plants, wherein name and be recognized the Babesia infecting sheep have sheep Babesia (
b. ovis), Mohs Babesia (
b. motasi), coarse Babesia (
b. crassi) and some Babesia U sps.Sheep Babesia by Rh (
rhipicephalus) hard tick propagate, be small-sized Babesia pathogenic by force, its biological characteristics and ox Babesia basically identical; Coarse Babesia is the large-scale Babesia that a kind of virulence is low, breeds in the mode of quaternary fission or binary fission, and its communication media tick and circulation way it be unclear that, and only finds in Iran and Turkey at present; And Mohs Babesia is the polypide the most extensive, characteristic of division is the most complicated that distributes in the Babesia of infection sheep, they are pathogenic different because of its difference distributed, as stronger in having of being separated with Mediterranean in southern Europe is pathogenic, and Northern Europe be separated pathogenic more weak, and these two kinds of Mohs Babesias be all by Haemaphysalis punctata (
haemaphysalis punctata) the large-scale Babesia propagated, at the Mohs Babesia that Sahara is separated, in form between known Mohs Babesia and sheep Babesia, but its communication media is not the tick of Haemaphysalis.According to pathogenic, difference, morphology, serology and the molecular classification Evolution analysis result to sheep and goat infectivity of Babesia, Uilenberg (2006) thinks in Mohs Babesia at least containing two or more kinds or subspecies.
China, before 1996, only has the report of 2-3 example sheep Babesia Gibsoni, then respectively in Gansu, there is the report of morbidity in Hebei, Liaoning, Yunnan, Shanxi, the ground such as Henan and Xinjiang.The Epidemic Scope of this disease in expanding trend year by year, may with Tick victor distribution range extensively have certain relation.This research team in last century Mo, the reconnaissance investigation of carrying out to China's part provinces and regions sheep Babesia Gibsoni.By blood inoculation and tick propagation experimentation, successively ground separation obtains the Babesia strains of 9 strain sheep in China Liaoning, Hebei, Gansu, Hubei, Xinjiang etc.Epidemiology survey finds that this disease is extensively popular in China, and some local harm are serious, positive rate more than 30%, the breeding sheep that cause of disease is introduced other places and lamb pathogenic comparatively strong, seriously restrict the breed improvement of sheep and the development of sheep husbandry.Carry out molecular classification research with the rrna 18S rRNA gene of pyriform worm (comprising Babesia and Taylor worm) to find; all there is nearer sibship Lintan, Gansu, the strain isolated of fiber crops when, Zhuhe, sky Ning County and Hebei, Hubei and Liaoning with Mohs Babesia; so name as Mohs Babesia (Liu et al., 2007; Guan et al., 2009), and carry out finding in the research of molecular classification with rrna 28S rRNA and transcribed spacer ITS gene, plastosome CoI gene etc.: the Mohs Babesia of China can be divided into two Asias to prop up; One is the Lintan strain of Mohs Babesia and the strain of Mohs Babesia God blessings of low pathogenicity, and two is highly pathogenic Mohs Babesia Ning County's strain and Mohs Babesia Hebei strain (Niu et al., 2009a).2010, (the Guan et al. such as Guan, 2010e) confirm that the positive serum that sheep is infected in Mohs Babesia Lintan strain whole worm antigen and the strain of Mohs Babesia God blessings has strong cross reaction, and there is no cross reaction with the positive serum of the Ning County's strain of Mohs Babesia and Hebei strain.These results conform to from the conclusion of Uilenberg: Chinese Mohs Babesia also at least may exist two different subspecies.Confirm through propagation experimentation, the communication media between the different subspecies of Mohs Babesia is not identical yet, and the communication media of some subspecies is not yet studied clear at present.
The Babesia Gibsoni of people is reported in nineteen sixty the earliest, primarily of two kinds infect people Babesia disease pathogen-vole Babesia (
b. microti) and difference Babesia (
b. divergens) cause, patient often with concurrent various syndromess such as severe anemia, interval high heat, sore muscle, tics, can cause death during severe infections.The Babesia of people is not infected before research in recent years shows, due to entomophila distribution range constantly extensively, the host range of the pathogenic cause of disease of carrier's Babesia is also in expansion, constantly there is (Schnittger L in the new pathogenic cause of disease of people's Babesia, et al., 2012), this disease progressively becomes a kind of global mankind and newly sends out parasitosis and be subject to public attention.Record according to current document, now mainly contain the ability that four large class Babesias have Zoonosis, the first kind is vole Babesia, and it is a kind of and the closely-related Zoonosis parasite of rodent, and U.S. most people infect Babesia case and caused by it; Equations of The Second Kind is rebaptism
b. duncani, the similar vole Babesia of form, but the two sibship is far away; 3rd class comprise difference Babesia (
b. divergence) and class difference Babesia,
b. venatorum(being also referred to as EU1); 4th class is Korea S newfound Babesia KO1 type, and very similar to the Mohs Babesia Hebei pathogen strain form of China, molecular classification analysis shows that both homologys are up to 98%, and nucleotide sequence only differs from 13 bases.
Present stage, mainly there is sheep Babesia-Mohs Babesia and the sheep Babesia U sp Xinjiang Strain of two kinds in China.But between the different Local Isolates of Mohs Babesia, because it is pathogenic, there is some difference for communication media and serology, binding molecule taxonomy shows that Mohs Babesia exists two different subspecies, i.e. the Mohs Babesia subspecies of low pathogenicity, as Lintan strain and God blessings strain; Highly pathogenic Mohs Babesia subspecies, as Ning County's strain and Hebei strain.
The gold standard that Babesia detects is the mode adopting blood smear dyeing microscopic examination, but blood smear dyeing microscopic examination result is subject to the impact of several factors, and recall rate is low, and accuracy is poor.Though Standard PCR, sleeve type PCR and the nuclei aoid methods such as real-time fluorescence PCR based on SYBR Green dyestuff have application, the shortcomings such as it is low that Standard PCR exists sensitivity, poor specificity, and sense cycle is long; Sleeve type PCR is highly sensitive, but the PCR of two steps reacts loaded down with trivial details, easily pollutes, and is not suitable for large-scale epidemiology survey.
