AI Summary AI generated
This standard specifies technical requirements for surveillance of highly pathogenic avian influenza, including epidemiological investigation, clinical examination, serological testing, and etiological detection. It applies to routine surveillance and post-outbreak monitoring of epidemic spots, areas, and threatened zones. Through sentinel animal placement, serum antibody detection (ELISA, HI), and pathogen confirmation, early detection and rapid response are achieved. The standard emphasizes field investigation and sampling when H5/H7 antibody titers reach 1:16 or above, providing technical support for avian influenza prevention and control.
本标准规定了高致病性禽流感监测的技术要求，包括流行病学调查、临床症状检查、血清学检测和病原学检测等方法。适用于常规监测和疫病发生后的疫点、疫区和受威胁区监测。通过岗哨动物设置、血清抗体检测（ELISA、HI）和病原学确认，实现早期发现和快速响应。标准强调对H5/H7亚型抗体效价达到1:16以上时需进行现场调查和采样检测，为禽流感防控提供技术支撑。
Key Sentences extracted from text
本标准规定了高致病性禽流感监测技术。
发现禽类急性死亡，并且出现脚鳞皮下出血，或鸡冠出血，或发绀，头部水肿，或肌肉和其他组织器官广泛性严重出血，就可以怀疑为高致病性禽流感。
用间接酶联免疫吸附试验(间接ELISA)或血凝抑制试验(HI)检测血清抗体(见GB/T18936)。
如果出现间接ELISA阳性，或H5或H7的HI效价达到1:16以上，须进行现场调查并采样进行病原学检测。
岗哨动物：在某地专门设立的易感动物群，一般禽群为30只-100只，通过临床观察和实验室检测来证实该地是否存在所监测的病原。
This standard specifies the surveillance techniques for highly pathogenic avian influenza.
If acute death of poultry occurs, with subcutaneous hemorrhage on foot scales, or comb hemorrhage, or cyanosis, head edema, or extensive severe hemorrhage in muscles and other tissues and organs, it can be suspected as highly pathogenic avian influenza.
Use indirect enzyme-linked immunosorbent assay (indirect ELISA) or hemagglutination inhibition test (HI) to detect serum antibodies (see GB/T 18936).
If indirect ELISA positive, or HI titer of H5 or H7 reaches 1:16 or above, field investigation and sampling for etiological detection must be conducted.
Sentinel animal: a susceptible animal group specially established in a certain place, generally 30-100 birds, to confirm whether the monitored pathogen exists in that place through clinical observation and laboratory testing.
