The main feature is the sheep cough, breathing Difficult, a large number of serous nasal fluid, weight loss, type Ⅱ alveolar epithelial cells and ciliated bronchial epithelial neoplasia [1]. Autopsy can be seen Sheep lung consolidation, retraction poor, larger, larger than the normal lung 2 to 3 times. The surface of the lungs have a solid circular miliary size gray Color nodules that adenoma, nodules occur fusion, the formation of irregular shape and large nodules. Airway filled with foamy liquid, lifted Two hind legs can flow out of the nostril foamy liquid that is a card-based cart test [2]. Sheep lung adeno-virus (JSRV) is the causative agent of sheep pulmonary adenoma. Contained within all genomes of normal sheep that have been studied There are about 20 copies of endogenous retroviruses (ERVs) that are closely related to JSRV. Because of their gene The structure is very similar to that of sheep lung adenoma virus, also known as the endogenous sheep lung adenovirus (enJSRV), in order to distinguish between sheep lung adenoma The virus is exJSRV [3]. Studies have shown that the gene structure of enJSRV and exJSRV are highly conserved among the gag gene, long terminal repeat (LTR) env gene at a larger difference, especially env gene encoding transmembrane protein region (TM) and long terminal repeat U3 region is 2 high Variable area. Therefore, in the detection of pathogen exJSRV, specific primers were designed at these two hypervariable regions and specific probes were prepared to exclude enJSRV [4] [5]. So far, no single method of diagnosing the disease has been established in the world [1]. There are three reasons for this. One is the potential of the disease Volt longer, longer duration, in the incubation period or obvious clinical symptoms of sheep is difficult to find. Second, ill sheep do not detect circulating anti-body Body, it is difficult to use conventional immunological methods for diagnosis, and third is the pathogen caused by the disease of sheep lung adeno-virus (JSRV) has not yet established in vitro Raising system, so conventional virus isolation and identification methods can not be used. The current diagnosis of the disease also depends mainly on clinical symptoms and pathology Weave examination. Therefore, the establishment of specific diagnostic criteria for the disease in the country's entry and exit inspection and quarantine, domestic sheep safety assessment, sheep inspection Epidemic mass and so has a very important significance. Detection of Sheep Lung Adenovirus Virus by Dot Assay1 ScopeThis standard specifies the sheep lung adenomatous virus nucleic acid dot blot hybridization reagents, materials and equipment, sampling, methods of operation, the results of determination. This standard applies to the detection of clinical suspected sick sheep and import and export of sheep lung tissue or peripheral blood samples of sheep lung adeno-associated virus nucleic acid, also Suitable for rapid detection of sheep lung adenomatosis pathogens in sheep clinical samples.2 Normative referencesThe following documents for the application of this document is essential.

Dot blotching is to be tested directly sheep tissue or blood-like DNA denaturation, spotted on the nitrocellulose membrane or nylon membrane, and then with the preparation of specific probes hybridization to detect the sample before Molecular hybridization of viral DNA. 3.2 Abbreviations The following abbreviations apply to this document.
