雞腺病毒
英文
chicken adenovirus-
The results of biological tests have demonstrated that allantoic fluid of the first passage virus did n ' t produce macroscopic pathogenic role to chicken embryos and after passaged for four times, gross lesions were observed in chicken embryo. the virus showed typical coronavirus under electron - microscope and it could n ' t form plaque in cef cells and could hemagglutinates chicken red blood cells after treatment with 1 % trypsin. to surprise, the virus replicated in cef cells also showed hemagglutination activity to chicken red blood cells. in addition, the spf chickens which inoculated with the virus isolated from the chicken damaged tissue showed clinical sign and grow lesion, but it ' s gross lesion did n ' t resemble to those of field outbreaks
生物學特性：雞胚尿囊液經離心、磷鎢酸負染后，電鏡觀察該病毒為典型的冠狀病毒；該毒株的第一代尿囊液對雞胚無肉眼可見的致病作用，當繼代到第5代后，胚體嚴重病變；病毒在雞胚中隨著接種時間的延長，其效價增高， 96h可達到48h的2倍；該毒株可在cef上生長，但不能形成明顯的蝕斑；經1胰酶處理后可凝集雞紅細胞；雞胚的第四代尿囊液病毒回歸動物體，病死雞腎臟呈典型的花斑腎，腺胃則未見肉眼可見的病變。The results showed that, at 12 48 hrs post infection, the bursal epithelial cells bore swollen and necrotic shape. the lymphoid cells in the medulla and cortex of lymphoid follicles had various degrees of degeneration and necrosis. the lymphoid follicles showed glandular structures or cystic vacuoles owing to the prolifetation of bursal epithelium and lymphocyte depletion. lymphoid follicles from bursa at 72 144 hrs post inoculation became atropy. marked proliferation of interfollicular and interstitial connective tissue was present
結果表明，病毒感染后12 48小時，雛雞法氏囊粘膜上皮細胞腫脹、壞死脫落，淋巴濾泡髓質部及皮質部淋巴細胞不同程度變性、壞死、排空，形成腺管樣結構或囊狀空泡，接毒后72 144小時，法氏囊淋巴濾泡淋巴細胞壞死排空，淋巴濾泡萎縮，網狀結締組織大量增生，而胚胎發育時期，法氏囊粘膜上皮腫脹變性，法氏囊淋巴濾泡形成延遲或不完整，淋巴濾泡內淋巴細胞缺乏或空虛。
