  • 종계장 질병 청정화에 대하여는 오래 전부터 논의 되어왔던 주제인 만큼 많은 양계인들이 나름대로의 풍부한 지식과 의견을 가지고 있고 어떻게 대비하여야 할 것인지를 충분히 알고 있을 것으로 생각한다. 그러나, 새 천년이 시작된 이 시점에 육계에서 가금티푸스발생이 급격히 증가하여 종계장에서의 질병 청정화가 새롭게 거론되고 있어 마음이 무겁기만 하다. 이와 같이 육계에서 가금티푸스 발생이 급격히 증가를 한 이유는 종계로부터 가금티푸스 균이 난계대전염되었기 때문인 것으로 보는 것이 일반적인 견해일 것이다. 따라서, 이 자리에서는 작금의 상황을 좀더 직접적으로 살펴보고자 종계장에서의 난계대 질병 중 현재 문제가 되고 있는 육계에서의 가금티푸스 방제에 관련하여 중점적으로 이야기 하고자 한다.

  • Human pathogenic viruses such as hepatitis A and E virus (HAV and HEV), which lead to acute liver failure and death, are foodborne pathogens associated with the consumption of virus-contaminated meats, filter-feeding bivalves, fruits, and salads. Two of the three swine farms examined in this study had HAV and HEV positive stool samples in a nested RT-PCR assay. The use of the immunomagnetic separation (IMS) facilitated the separation of HAV through interactions between the ligand on the virion surface and the antibody from the swine feces containing both HAV and HEV. The nested RT-PCR analysis was performed for the detection of HAV obtained from hepatocarcinoma cell line (PLC/PRF/5) contaminated with eluent fraction of IMS. This indicated that IMS has the potential to simultaneously isolate and concentrate target viruses by changing antibodies linked on the magnetic beads.

  • Soybean stunt virus (SSV) was newly isolated in Korea from naturally infected soybeans (Glycine max). The main symptoms caused by this virus on soybean cultivars are crinkling, mild mottling and reduction in plant size. This virus induced local lesion on the inoculated leaves of Chenopodium amaranticolor, C quinoa and Vigna sinensis, and mosaic symptoms on Nicotiana tabacum (Bright yellow, KY-57). The virus was inactivated at 60C, and was infectious at dilution of $10^3$. Extract juice became infective 3 days later at room temperature. The virus was transmitted by green peach apid (Myzus persicae). This virus closely is related serologically to cucumber mosaic virus. The virus particles observed in the electron microscopy were spherical types of 30mm in diameter.

  • A yellow stripe and bud benting disease of soybean was commonly observed on the field at Suweon area. The causal agent was identified as alfalfa mosaic virus (AMV) by indicator plant reactions, physical properties, serological test and electron microscopy. AMV produced vein clearing, top necrosis, top bent and mottling on the parts of soybean plants. Local lesions were produced on the inoculated leaves of Vigna sesquipedialis, Vicia faba and Tetragonia expansa, while Chenopodium am, anticolor, C. quinoa, Pisum satvium, Petunia hybrida and Nicotiana tabacum 'Bright yellow' were systemically infected. The thermal inactivation point was $60^{\circ}C$, dilution end point was $10^{-3}$, and longevity in vitro was 2 days at room temperature. AMV from soybean was reacted with AMV - antiserum in agar gel diffusion test. Electron microscopy of AMV from soybean exhibited bacilliform particles of 60nm in length.

  • 제주지역 돼지에서 각종 전염성 질병 원인체에 대한 항체를 조사하여 그간 전염성 병원체에 대한 역학조사가 미진하였던 부분을 보완하여 질병의 분포를 파악하고자 1995년부터 1996년에 걸쳐 제주도 전역에서 돼지의 혈청을 채취하여 각종 병원체에 대한 항체 분포율을 조사하였다. 본 연구에서 검사한 돼지 혈청 시료에서는 돼지 오제스키병 바이러스에 대한 항체는 전혀 검출되지 않았다. 돼지 콜레라바이러스에 대한 항체는 기대 수준 이하로 낮아 백신접종이 원활히 수행되고 있지 않음을 시사하였으며 특히 농장에 따라 항체 보유돈과 항체 음성돈이 혼재하는 농장과 항체가 전혀 검출되지 않는 농장 등 돼지 콜레라 방역의 사각지대가 존재할 가능성이 있음을 보여주었다. 유 사산 원인체인 돼지 파보바이러스 및 뇌심근염에 대한 항체가가 다양하게 나타나 일부 문제가 있을 것으로 사료되었다. 돼지 생식기호흡기증후군(PRRS) 바이러스에 대한 항체 분포율은 내륙 보다 다소 낮게 나타났고, 돼지 influenza virus, 위축성 비염, 흉막 폐염 등 각종 세균성 질환에 대한 항체수준도 다양하게 나타났다. 본 혈청학적인 연구결과는 제주지역에서의 양돈방역 정책수립 및 질병방제의 기초자료로 유용하게 이용될 것으로 사료된다.

  • A total of 3 hybridoma clones producing monoclonal antibody (MCA) against infectious laryngotracheitis virus (ILTV) was established by somatic cell hybridization between mouse myeloma cells and spleen, cells from mice immunized with ILTV. The MCAs were screened by the indirect flourescent antibody (IFA) staining and the specific hybridomas were cloned by limiting dilution method. The MCAs produced by the 3 hybriomas were all classified as immunogloblin G and found to be reacting against common antigen(s) of high and low pathogenic ILTV examined. The titer of these antibodies in mouse ascitic fluid was from $10^5$ to $10^6$. Indirect fluorescent antibody test using these antibodies was found to be quite effective for the detection of ILTV from infected chickens being the most sensitive among the test methods adopted.

  • Antifungal substances were isolated and identified from garlic and taxus extracts to develop safe and broad fungicide. The inhibitory effect of seedborn disease of sesame, pepper, radish, chinese cabbage by formulation of antifungal substances was investigated. The antifungal substance isolated through column chromatography from garlic and taxus extracts was confirmed by GC-MS as allicin($C_6H_{10}OS_2$) and taxol($C_{47}H_{51}NO_{14}$) and the quantified content from each extracts by HPLC analysis was 0.62%, 0.29%, respectively. The formulation composed of garlic and taxus extracts controlled effectively the seedborn fungi tested in this study at 10X dilution, but at 100X dilution the inhibitory effect decreased. Phytotoxicity of these formulations did not recognized.
