bursa fabricius
解釋
法氏囊-
The chickens and chicken embryos were inoculated with variant serotype isolate e of infectious bursal disease virus using cloacal, nosal routes or via the allantoic cavity route, and the histopathological features of the bursa of fabricius of the ibdv _ infected chickens at various intervals of time were systematically investigated
本試驗全面而系統地觀察了傳染性法氏囊病病毒變異e株，通過泄殖腔、鼻腔和尿囊腔接種雛雞和雞胚后不同時間法氏囊的組織形態學變化。 -
Spf chickens with 21 - day - old were infected subcutaneously with oil - emulsion vaccine of ibdv of germinal or cellcular and injected intramuscularly with different dosages bursin which gain through ultrafilter. lt is proved that bursin of chickens and ducks can both shorten the time of antibody induced against ibdv, raise the level of serum antibody. they make chickens obtaining strong immunocompetente in a short time. agp liters of the group of infecting 0. 4mlcbs + ibdv of germinal and 0. 8mlcbs + ibdv of cellcular or 0. 8mldbs + ibdv of germinal and cellcular are higher than immune control group about 2 liters averagely. the chickens were inoculated with ibdv live vaccine mixed with the different dosages of lyophilized bursin by the eye drop method. the results sugest that cbs or dbs of different dosages can both improve the antibody inducation to different age chickens against ibdv. they may also alleviate the immunological injury of activated virus to bursa of fabricius. and promote the repairation of the lesion. it can be found that bs can raise body weight gain and feed coversion ratio
將超濾獲得的法氏囊活性肽分別以不同劑量肌肉注射21日齡spf雞，同時頸部皮下注射ibd胚毒或細胞毒滅活苗，結果表明：雞、鴨法氏囊活性肽都能夠縮短ibd油苗誘導產生抗體的時間，提高抗體水平，使雞可以在比較短的時間內獲得堅強的免疫。 0 . 4mlcbs胚毒組和0 . 8mlcbs細胞毒組或0 . 8mldbs胚毒和細胞毒組的agp抗體滴度平均比免疫對照組高2個滴度。將法氏囊活性肽與ibd活苗聯合免疫雞，結果表明：不同劑量的cbs和dbs都可以對不同日齡雞ibd抗體的產生有不同程度的促進作用；還可以減少弱毒對雞法氏囊組織的損傷，加快其修復。 -
Extract the bursin from the bursa fabricius of chichens and ducks through the ultrafilter with loooda filter. ( the bursin of chickens - cbs. the bursin of ducks - dbs ) determine the major constitution by high - performance liquid chromatography ( hplc ) and thin - layer chromatography ( tlc ). it is proved that there is bursin ( bs ) in two extractions. caculate the quantitation of bursin in the extraction of the bursa fabricius of chickens and ducks. it can be found through tlc that the quantitation of cbs in the extraction of the bursa fabricius of chickens is 1. 436mg / ml and the quantitation of dbs in the extraction of the bursa fabricius of ducks is 4. 035mg / ml. the result obtained through hplcis that the quantitation of cbs is 1. 199mg / ml and dbs is 3. 316mg / ml
採用超濾法從正常雞、鴨法氏囊組織中提取分子量小於1000da的物質，分別以薄層層析法和高壓液相色譜法檢測其主要成分，證明兩種超濾液中均有法氏囊活性肽（囊素三肽， bursin ， bs ）的存在，分別計算雞、鴨法氏囊提取物中的囊素三肽的含量。薄層層析方法求得雞法氏囊提取物中的bs含量為1 . 436mg / ml ，鴨法氏囊提取物中的bs含量為4 . 035mg / ml ；高壓液相色譜的方法求得雞法氏囊提取物中的貼含量為1 . 199mg / ml ，鴨法氏囊提取物中bs含量為3 . 316mg / ml 。 -
Three ibdv strains, designated as zj2000, zj991 and zj992, were isolated from bursa of fabricius of the sick chicken flocks in hangzhou, shenzhou, and ningbo of zhejiang province. the isolates could react with ibdv positive reference serum in the agar immune - diffusion test and caused 30 - 100 % mortality when passaged in chicken embryos. chickens inoculated with these isolates exhibited clinical and pathological signs typical of infectious bursal disease
從浙江省杭州、嵊州，寧波等地暴發疑似傳染性法氏囊病的雞群中採集法氏囊病料（編號分別為zj2000 、 zj991 、 zj992 ） ，分離病毒，經瓊脂免疫擴散試驗、動物回歸試驗、雞胚回歸試驗和電鏡觀察等證實所分離的3株野毒是傳染性法氏囊病病毒。 -
Bursa of fabricius
腔上囊法氏囊 -
Infectious bursal disease virus ( ibdv ), the causative agent of infectious bursal disease ( ibd ), causes immunosuppression in young chickens by destroying the precursors of b lymphocytes in the bursa of fabricius
傳染性法氏囊病（ ibd ）是由傳染性法氏囊病病毒（ ibdv ）引起的急性接觸性傳染病，是危害世界養禽業的主要傳染病之一。
