[0101] 2.1 RNA extraction:

[0102] Take n 1.5ml sterilized centrifuge tubes (n = number of samples + 1 tube of negative control + 1 tube of positive control) and mark them. First add 600 μL of lysate (the lysate is highly corrosive, do not get it on th...

Embodiment 2

[0133] Embodiment 2, the sensitivity test of kit

[0134] 1. Materials:

[0135] Methods The virus strains used in the research process were bovine enterovirus and foot-and-mouth disease virus isolated and preserved in our laboratory.

[0136] 2. Method

[0137] Bovine enterovirus and foot-and-mouth disease virus cell cultures were used as 10 -1 、10 -2 、10 -3 、10 -4 、10 -5 、10 -6 、10 -7 、10 -8 、10 -9 、10 -10 The multiple dilutions were carried out for multiple RT-PCR detection, and at the same time, the virus of each dilution was inoculated into BK cells, and the sensitivity of the two methods was compared.

[0138] 3. Results

[0139] The cell cultures of bovine enterovirus and foot-and-mouth disease virus were serially diluted by 10 times, and the assembled kits A and B were used for detection respectively. The test results showed that the detection limit could reach 10 -6 , which is equivalent to cell separation and culture identification, but the detection tim...

[0144] 2. Method

[0145] Use the established RT-PCR method to detect a variety of common cattle viruses (including bovine enterovirus, bovine infectious rhinotracheitis virus, bovine viral diarrhea virus, foot-and-mouth disease virus, vesicular stomatitis virus) to verify the method specificity.

[0146] 3. Results

[0147] The results showed that no matter whether kit A or kit B was used, the established method had no cross-reaction with the above-mentioned viruses, and the specificity was good.

Abstract

The invention discloses a nucleotide sequence for detecting bovine enterovirus and foot-and-mouth disease virus, and the nucleotide sequence for detecting the bovine enterovirus and the foot-and-mouth disease virus is as shown in SEQ (sequence) ID (identity) NO: 1 to SEQ ID NO: 4 in a sequence table, wherein the SEQ ID NO: 1 and the SEQ ID NO: 2 are a sense primer and an antisense primer for detecting the bovine enterovirus respectively; and the SEQ ID NO: 3 and the SEQ ID NO: 4 are the sense primer and the antisense primer for detecting the foot-and-mouth disease virus respectively. The invention further discloses a kit containing the primers for detecting the bovine enterovirus and the foot-and-mouth disease virus. The kit has the characteristics of quickness, sensitiveness, specificity, stability and good repeatability.

Description

technical field [0001] The invention relates to a nucleotide sequence and a detection kit for detecting bovine enterovirus and foot-and-mouth disease virus, especially a detection nucleotide sequence and a kit for multiplex RT-PCR detection of bovine enterovirus and foot-and-mouth disease virus, not only applicable to animals The accurate detection of tissue samples can also be applied to the detection of living animal samples (throat swabs, anal swabs, feces, serum, herpes skin, herpes fluid, conjunctival secretions, etc.), and can be used for domestic screening of bovine enteroviruses. Inspection and entry-exit quarantine, as well as simultaneous detection and differential diagnosis of bovine enterovirus and foot-and-mouth disease virus, etc., belong to the field of animal disease detection, inspection and quarantine. Background technique [0002] Both bovine enterovirus and foot-and-mouth disease virus are members of the Picornaviridae family. Picornavirus is an extremel...
