Problems solved by technology

However, due to the large number of Zika virus ZIKV subtypes and the high homology of the conserved regions with other flaviviruses, it is difficult to design specific primers for real-time RT-PCR
[0004] At present, there is no effective and accurate detection method for Zika virus ZIKV

Abstract

The invention provides a detection primer for the zika virus and applications of the detection primer, belonging to the field of medical examination. The detection primer for the zika virus provided by the invention can accurately and specifically detect the zika virus, the zika virus can be detected even when the concentration is as low as 1x10<1> copies / [mu]L, and thus the sensitivity is high. With the adoption of the detection primer, the accuracy in detecting the zika virus can be improved, a kit for detecting the zika virus prepared by adopting the detection primer can be conveniently applied, the detection is rapid and sensitive, and the experimental result is accurate and reliable.

Description

technical field [0001] The invention relates to the field of medical testing, in particular to a Zika virus detection primer and its application. Background technique [0002] Zika virus ZIKV (zika virus, ZIKV) is a mosquito-borne virus belonging to the family Flaviviridae. It is a single-stranded positive-sense RNA virus with a total gene length of about 11Kb. The diameter of the virus particle is 40-70nm, with an envelope , containing 10794 nucleotides, encoding 3419 amino acids, ZIKV viral gene encoding 3 structural proteins: capsid protein (C), membrane precursor protein (pr M) and envelope protein (M), and 7 non- Structural proteins (NS1, NS2a, NS2b, NS3, NS4a, NS4b and NS5). According to the genotype of Zika virus ZIKV, it is divided into African type and Asian type. [0003] Clinical detection methods include general blood routine examination, serological examination, virus isolation and culture, etc. Serological methods are only suitable for acute or convalescent ...
