Heamagglutination tests were applied to detect virus in allantoic fluid of chicken embryos which were infected by b95 gathered from the vaccinated chickens " cloacal and oral cavity. the results show that the virus may be detected from 2 days to 11 days after the chicken being vaccinated. the hi antibodies were measured by heamagglutination inhibition tests. there is no significant difference between the immunized and the control chickens which were fed in one case. chickens were immunized with b95 by different immunization meathods or with different vaccines by the same meathod. lt is demonstrated that eyedrop, drinking water, spray or muscle injection all can stimulate good effects, but eyedrop and spray seem to be the best meathods. b95 immunized chicken have relatively higher hi titers and it also can last for a longer time than others
但如果兩者相隔10天以上免疫, b95免疫不受h120的影響;如果同時免疫b95和h120 ,加大b95的免疫劑量也能獲得良好的免疫效果。用棉拭子采b95免疫雞口腔、泄殖腔的分泌液,檢測其中病毒的存在,結果免疫后2 11天雞口腔和泄殖腔中均有病毒的存在,說明b95免疫雞帶毒時間長。研究結果表明, b95具有不受母源抗體干擾、 hi抗體產生快、水平高、持續時間長、同居擴散性強等特點,因此b95是一株優良的、具開發前景的新的新城疫疫苗株。In recent years, the outbreak of nd appear some new characters, it is reported that the amount of immunity defeat on nd increased, even chicks with high hi titer can be infected by ndv virulent strain. the gene - engineering vaccine is badly needed to control nd outbreak. so newcastle disease virus strain b95, a naturally avirulent and heat stable strain, was introduced from australia
新城疫是國際獸疫局公布的16種烈性傳染病之一。近年來,新城疫的爆發出現了許多新特點,免疫失敗報道增多,甚至抗體水平較高的雞群也發病。為控制新城疫的爆發,急需研製基因工程苗。Newcastle disease is a highly contagious and economically most important disease of poultry. the disease also inflicts many other avian species. the disease varies in degree of severity ranging from mild, inapparent infecion to severe disease. based on the severity of the disease in chickens, the causative agent of the disease, newcastle disease virus ( ndv ), is divided into three pathotypes : ( 1 ) the lentogenic strains, which cause mild inapparent infection ; ( 2 ) the mesogenic strains, which cause mild respiratory symptoms with low mortality ; ( 3 ) the velogenic strain, which are highly virulent and cause high mortality
新城疫( newcastledisease , nd )是由新城疫病毒( newcastlediseasevirus , ndv )引起的侵害禽類的急性高度接觸性傳染病,是家禽傳染性疾病中危害最嚴害的疫病之一,由於對世界養禽業危害極大,故被國際獸疫局確定為類傳染病。在傳染性疾病的預防中,疫苗是減少易感人群而被最廣泛採用和最有效的途徑。All the result showed that ndv f48e9 strain has its own speciality compared with other five ndv strains, and there were many difference between velogenic strains and lentogenic strains. so the infectious cdna of rnesogenic strains and lentogenic strain was far from enough to understand the replication, pathogenicity of ndv and the interaction between ndv and host cells, and the infectious cdna of velogenic strains ( eg. f48e9 ) was required to explain the relationships between structure and function
本研究成功地獲得了ndvf48e9 t因組的核昔酸序列,並構建了表達ndvf48e9基因組cdna的低拷貝表達載體休f48e9 ,為構建新城疫病毒強毒株f48e9株的感染性cdna奠定了物質基礎,進一步研究ndv的生物學特性、結構與功能的關系;進一步探討影響ndv毒力的因素、以及研製新型疫苗載體提供了可靠保證。The immunologic enhancement of lactobacillus dna on the newcastle disease inactived vaccine and the avian influenza disease inactivated vaccine

美國研究者已經成功地研究出一種用於新城雞瘟的疫苗,但還沒有用於人身上的疫苗。By morphologic examination, structure characteristics ^ biological property n serological tests and pathology characteristic study, this virus was identified as the medium virulence chicken. new castle disease virus ( ndv ), whose pathology characteristics were appeared different from those of the standard virulence ndv. la sola vaccine could not give good protection against the infection of this virus isolate
用spf雞胚在吉林省患病雞群中分離到一株病毒,經病毒形態學、結構特徵、生物學、血清學及致病性等試驗研究,確定該病毒為雞新城疫強毒,對lasota免疫雞的致病性及其致死率與雞新城疫標準強毒e _ 9f _ ( 48 )對比差異顯著, lasota疫苗對該株病毒免疫保護效果不理想。Preparation and application of inactivated oil emulsion vaccine against newcastal disease and colibacillosis
雞新城疫一多價大腸桿菌二聯油乳滅活苗的研製與應用Researchers in the united states have developed one for ( newcastle ) disease in chickens, but so far there are no products for humans
美國的研究人員已經研製出了一種雞新城疫疫苗,但到目前為止適合人類的產品。This strain ' s virulence was judged by mean death time of chick embryos ( mdt ), intracerebral pathogenicity index in day - old chicks ( icpi ) and intravenous pathogenicity index in 6 - week - old chickens ( ivpi ) and it was found to be the virulent strain. at last, it was tested by the recurrent infection and found that it was the newcastle disease virus ( ndv ), and it was named hbg - 1 strain. in order to find the difference of the cleavage site of this strain with f48e9 and ? 30 strain, a part of the cleavage site of fusion protein gene fragment was amplified by rt - pcr using a primer and sequenced. the sequence analysis showed this strain had low homology with f4ge9 and cso. a phylogenetic tree based on the published sequences of ndv reference strains was constructed and showed the isolated strain hbg - 1 belonged to the genotype w ndv, a novel genotype ndv
為了進一步探尋分離株與標準株的異同,又採用rt - pcr方法,擴增獲得分離株f _ o裂解位點附近的基因片段,經測序后與國際上已發表的新城疫病毒的核酸序列進行比較,結果表明其與標準株和疫苗株之間的同源性較低,僅為82 86之間。經系統發育進化樹分析后,判定該分離株為新城疫病毒( ndv )基因型。運用計算機軟體對其裂解位點處的氨基酸序列進行預測和分析,結果表明該分離株為新城疫病毒強毒株並具有基因型的典型結構特徵。In recent years, there is occurrence nd continuously in the nd la sola vaccine immunity and high antibody chicken, some scholars reported its reason relation with not only immunity method, path, vaccine etc., but also poison and different genotype. one virus isolate was obtained from the diseased chicken flocks in jilin province using spf chicken embryos
近年來,在新城疫lasota疫苗免疫雞群及高抗體雞群中不斷有新城疫的發生,有學者報道,其原因不僅與免疫方法、途徑、疫苗等有關,更重要的是與新城疫毒株的變異,不同基因型的出現有關。Investigation on hbsag positive rate and immunization coverage rate of hepatitis b vaccine in xincheng district
