avian encephalomyelitis 解釋
雞腦脊髓炎
  1. Biogen - tab is an effective and invaluable medicine for many poultry diseases, particularly chronic respiratory disease, infectious coryza, salmonelloses fowl typhoid and paratyphoid infection, blue comb disease, fowl cholera, coccidiosis, and leucocytozoon disease. the diseases infected by virus, such as newcastl disease, avian encephalomyelitis are found not to be effected by biogen - tab treatment

    愛禽美對許多家禽疾病是相當有效的藥品,特別是慢性呼吸器病,通稱crd ,傳染性可利查,沙士桿菌病如家禽傷寒,副傷寒,藍冠病,家禽霍亂,球蟲病,及白冠病等但有些疾病,由病毒感染者無效如新城雞瘟,傳染性喉頭氣管炎

  6. Avian encephalomyelitis virus ( aev ) is a picornavirus with a predilection for the central nervous system and other parenchymous organs of chickens that is transmited by the oral - faecal route. the virus may be spread by the vertical and horizontalroutes, and because of its great stability, contaminated areas may remain infectious for long periods. the egg - adapted van roekel strain is highly neurotropic and does not grow efficiently in the enteric tract of the chicken, and the field isolates of aev is usually enterotropic. despite this. the virion polypeptides of both naturally - occurring strains and the van roekel strain are antigenically identical

    侵害雞的中樞神經系統和其它實質性器官,該病毒通過口-糞途徑傳播,具有水平和垂直傳播的能力。由於它極大的穩定性,被污染的區域可能長期保持傳染性。雞胚適應株vanroekel是高度嗜神經的,並且在雞的腸道內不能有效的生長,而野毒株卻是嗜腸道型的。
  7. Avian encephamyelitis ( ae ), which is also called epidemic tremor, characterized by nonsuppurative encephamyelitis, is caused by avian encephalomyelitis virus and has a sign of decreasing egg production. in adult chickens and decreasing hatching rate in fertilized eggs and has 40 % - 60 % of incidence and 25 % of mortality

    該病發病率為40 60 ,死亡率為25左右。成年雞感染后出現產蛋率下降,種蛋出雛率降低。但雛雞感染aev的早期血清中的igm , igg系統的變化規律尚未見報道。
  8. The research consist of four parts. the first part is multiplication, purification and electron microscope examination of the avian encephalomyelitis virus. a 1 : 5 dilution of isolate - nh937 of aev and control group of pbs were inoculated to susceptible 6 - day - old chickens embryos. respectively. after incubation for 10 days, the urinay vesicle liquid was collected. making a comparison the size of the chickens embryos between the test group and the control group, the results showed that the size of the control group is bigger than that of the test group. purified virions were examined under the electron microscope, the result revealed that there are a lot of virions and the aev - nh937 was multiplicated in embryos. the second part was seguence analysis of the genome of the aev - nh937. nine pairs of primers were designed according to published calnek vaccine strain of aev

    本研究共分四個部分:第一部分為aev的增殖,純化和電鏡觀察,用1 : 5倍稀釋的aev - nh937株和陰性對照pbs分別經卵黃囊接種於6dspf雞胚,繼續孵化10d后,收集尿囊液。比較接種組和健康對照組雞胚的大小,結果顯示,健康對照組雞胚明顯大於接種組。分離、提純aev ,把純化的病毒在電鏡下觀察,證明確有大量aev病毒粒子存在,說明aev在雞胚中成功擴增;第二部分是aev - nh937基因組的序列測定工作。
