Abstract:
PURPOSE: A method for diagnosing porcine circovirus 1 and 2 from Postweaning Multi-systemic Wasting Sysdrome(PMWS) or Porcine Der- matitis and Nephropathy Syndrome(PDNS) is provided to improve accuracy of diagnosis. CONSTITUTION: A method for diagnosing porcine circovirus type 1 and 2 from Postweaning Multi-systemic Wasting Sysdrome(PMWS) or Porcine Der- matitis and Nephropathy Syndrome(PDNS) comprises: a step of loading DNA and common probe(sequence number 3) of porcine circovirus(sequence number 3) on a nylon membrane; a step of amplifying the DNA isolated from sample of outside; a step of hybridizing PCR amplified product with nylon membrane; a step of dyeing hydridized product with nitrotetrazolium and bromo-chloro-indolyl phosphate; and a step of determining negative or positive.

Abstract:
PURPOSE: A detection kit for swine cholera virus antibody using immunochromatography method is provided, thereby rapidly detecting the swine cholera virus antibody, and enabling the in-situ detection of the swine cholera virus antibody, so that the swine cholera virus antibody can be rapidly detected in farmhouses. CONSTITUTION: The detection kit for swine cholera virus antibody using immunochromatography method is prepared by binding a protein antigen(1), preferably E2 protein of swine cholera virus to strip type nitrocellulose membrane(5); and binding anti-swine IgG antibody(2) to the opposite side of the nitrocellulose membrane(5). The method for detecting the swine cholera virus antibody comprises the steps of: contacting a swine blood sample with the nitrocellulose membrane(5) by spotting the sample on the sample pad through a sample loading hole(4); transferring the swine blood sample to the swine cholera virus antigen(1) via the nitrocellulose membrane(5), and transferring the anti-swine IgG gold conjugate adsorbed in a conjugate pad to the absorbing pad(3); and measuring the occurrence of red purple by the antigen-antibody reaction followed by the gold particle reaction with the antigen-antibody conjugate in the antigen fixed region(1).
Abstract:
PURPOSE: Recombinant porcine adenovirus type 3 expressing Japanese encephalitis virus gene NS1 and use thereof are provided, thereby inducing immunity to Japanese encephalitis virus in human, and improving stability of the vaccine by using adenovirus. CONSTITUTION: A recombinant vector of porcine adenovirus type 3 expressing Japanese encephalitis virus gene NS1, pPAV3E3-NS1(KCTC 10377BP), is prepared by removing E3 gene of porcine adenovirus type 3, and inserting the Japanese encephalitis virus gene NS1 under the control of E3 promoter, wherein the Japanese encephalitis virus gene NS1 has the nucleotide sequence set forth in SEQ ID NO: 1. A host cell transformed with the recombinant vector pPAV3E3-NS1(KCTC 10377BP) is provided. The recombinant porcine adenovirus type 3 expressing Japanese encephalitis virus gene NS1(PAV3E3-NS1) is obtained by culturing the transformed host cell. A vaccine for Japanese encephalitis virus comprises the recombinant porcine adenovirus type 3 expressing Japanese encephalitis virus gene NS1.

Abstract:
본 발명은 국내 돼지 사육농가에 심각한 경제적 피해를 야기시키는 돼지의 주요 전염병의 백신제조에 사용될 수 있는 발현 벡터 및 이를 이용하여 재조합 바이러스를 제조하는 방법에 관한 것으로, 본 발명의 발현벡터는 돼지아데노바이러스 4형의 E3 유전자 부위를 제거하여 E3 프로모터하에 삽입된 외래 유전자가 발현될 수 있도록 제작한 플라스미드이고, 유전자 재조합 돼지아데노바이러스 4형은 발현벡터에 외래 유전자를 삽입한 후, 이를 돼지아데노바이러스 4형 게놈 유전자와 대장균내에서 동질성 재조합(homologous recombination)하고, 이를 리포펙틴을 사용하여 돼지신장세포(porcine kindey)에 형질도입시켜 바이러스를 선발한 것이다. 한편, 본 발명의 발현벡터에 삽입될 수 있는 외래 유전자는 최대 약 4.0kb의 크기를 갖는 것으로, 예를 들면 돼지 유행성 설사병 바이러스 스파이크(spike) 유전자, 돼지 전염성 위장염 바이러스 스파이크 유전자 등이 있다.
