Scope
This standard specifies the technical requirements for diagnosis of avian reticuloendotheliosis. It includes two aspects: detection of specific serum antibodies against avian reticuloendotheliosis virus (REV); detection of infectious REV in pathological materials and biological products. This standard is applicable to: detection of REV-specific antibodies to determine whether poultry populations (farms) or individuals have been infected with REV; particularly suitable for batch sampling inspection of whether REV infection exists in SPF chicken farms; detection of whether infectious REV exists in pathological materials of suspected sick poultry or certain attenuated vaccines.
本标准规定了禽网状内皮增生病诊断的技术要求。它包括两方面：对禽网状内皮增生病病毒(REV)特异血清抗体的检测；病料及生物制品中传染性 REV 的检测。本标准适用于：检测 REV 的特异性抗体，用以判断禽群体(场)或个体是否感染过 REV；特别适用于 SPF 鸡场中是否存在 REV 感染的大批样品的抽检；检测疑似病禽的病料或某些弱毒疫苗中是否存在传染性 REV。

Veterinary laboratories and quarantine personnel use this standard to diagnose avian reticuloendotheliosis by detecting serum antibodies or isolating the virus. It is critical for controlling REV transmission in poultry flocks, ensuring biosecurity in SPF chicken farms, and assessing the risk of vaccine contamination.
兽医实验室和检疫人员使用该标准来诊断禽网状内皮增生病，通过检测血清抗体或分离病毒确认感染。该标准对控制REV在鸡群中的传播、保障SPF鸡场生物安全以及评估疫苗污染风险至关重要。
AI Summary AI generated
This standard specifies diagnostic technical requirements for avian reticuloendotheliosis (REV), including serum antibody detection and virus isolation and identification. REV is a C-type retrovirus that infects multiple avian species, causing growth retardation, immunosuppression, and tumors, often with co-infections. The standard applies to SPF flock monitoring, suspected case diagnosis, and vaccine contamination testing, playing a key role in controlling REV transmission and safeguarding poultry health.
本标准规定了禽网状内皮增生病（REV）的诊断技术要求，包括血清抗体检测和病毒分离鉴定。REV是一种C型反转录病毒，可感染多种禽类，引起生长迟缓、免疫抑制和肿瘤，常与其他病毒混合感染。标准适用于SPF鸡场监测、疑似病例诊断和疫苗污染检测，对控制REV传播和保障养禽业健康具有重要意义。

REV 属C-型反转录病毒,有囊膜,呈球形 ,直径 80 um~110 ym。
REV 被列为鸡群中除马立克氏病病毒(MDV)和 ALV 外的第三类致肿瘤病毒。
当种禽在开产后才感染 REV 时 ,会有一短暂的病毒血症期,此期间可造成垂直感染。
在病理上诊断为马立克氏病肿瘤或J-亚型白血病肿瘤的现场样品中 ,在分离到马立克氏病病毒(MDV) 或 J-亚型白血病病毒(ALV -J)的同时 ,也有近50%的样品同时分离到 REV。
This standard specifies the technical requirements for diagnosis of avian reticuloendotheliosis.
REV belongs to C-type retrovirus, has an envelope, is spherical, with a diameter of 80 nm to 110 nm.
REV is listed as the third type of oncogenic virus in chickens besides Marek's disease virus (MDV) and ALV.
When breeding poultry are infected with REV after laying, there will be a transient viremia period, during which vertical transmission can occur.
In field samples pathologically diagnosed as Marek's disease tumor or J-subtype leukemia tumor, nearly 50% of samples also had REV isolated simultaneously with Marek's disease virus (MDV) or J-subtype leukemia virus (ALV-J).
