H5N1亚型禽流感灭活疫苗免疫鸵鸟后抗体消长规律及免疫程序的研究

为了探讨鸵鸟对H5亚型禽流感灭活疫苗的免疫原性,做好鸵鸟禽流感的防控工作,采用哈尔滨兽医研究所研制的重组H5N1亚型禽流感疫苗,不同剂量免疫鸵鸟,用HI方法检测母源抗体和免疫抗体,根据母源抗体的衰减和免疫抗体的消长规律确定首免和再免日龄.结果表明,雏鸵鸟母源抗体能维持约3周～8周;8周龄时分组首免,C1组产生的免疫反应优于C2组,抗体峰值能达到7.50 log2,维持时间为9周左右;17周龄时C1组以3.0 mL/羽进行二免,2周后抗体达到7.40log2,3周～7周抗体维持在高峰值,最高达8.80log2,以后逐渐下降,有效抗体水平能维持至接种后25周左右.二免后25周进行三免,以5 mL/羽三免后2周抗体可达到9.80log2,2周～4周抗体维持在最高峰,以后缓慢下降,期间抗体时有起伏,但有效抗体水平约可维持1年时间.三免后45周内抗体水平合格率均在70%以上.根据抗体消长规律,初步推荐了鸵鸟的免疫程序.     

鸵鸟红细胞免疫功能研究

应用红细胞Ｃ３ｂ受体花环（Ｃ３ｂＲＲ）和免疫复合物花环（ＩＣＲ）试验，证实鸵鸟红细胞表面存在补体Ｃ３ｂ受体（Ｃ３ｂｒｅｃｅｐｔｏｒ，Ｃ３ｂＲ），表明红细胞免疫系统（Ｒｃｄｃｅｌｉｍｍｕｎｅｓｙｓｔｅｍ，ＲＣＩＳ）的概念亦适用于这种动物；鸵鸟红细胞不但有传统医学观念上的功能，而且还可借助ＣＲ１（ＣｏｍｐｌｅｍｅｎｔｒｅｃｃｐｔｏｒｔｙｐｅＩ）进行免疫粘附，并以此为基础，表现出各种重要的免疫功能。     

荚果蕨露地引种栽培试验研究

本文对露地引种栽培荚果蕨的生长发育规律、环境因子对其生长、发育及园林观赏效果的影响作了研究.结果表明;在北京地区露地栽培中,荚果蕨4月上旬萌发,营养生长迅速;6月中旬始孢子叶生长;10月下旬枯萎,绿色期较长.对土壤适应性极强,尤耐碱性土;全光下可正常生长,但适当遮荫观赏效果最佳,喜湿润空气,忌土壤长期积水.     

Poisoning in ostriches following ingestion of toxic plants - field observations

Data from post-mortem and field studies were obtained that discussed poisoning in ostriches following ingestion of toxic plants. From the notes, all plants studied caused death in ostriches and there was systemic organ damage. Poisoning from Sarcostemma viminale (Melktou) resulted in beak patting, muscular tremors and head flopping, followed by collapse and violent kicking before death. Ingestion of Combretum oatesii (Red wings) seeds from plants in free grazing pastures resulted in vomiting, restlessness, eyelid flicking, collapse and kicking movements. Dichapetalum cymosum (Gifblaar) killed an ostrich after episodes of shaking legs, rapid respiration and bradycardia and hyperaemia of the lungs, liver and kidneys. Poisoning from Senecio sceleratus (Ragwort) caused skin haemorrhages and bleeding in tracheal mucous membranes, the pericardium, diaphragm and interperitoneal membrane. Consumption of drupes from Melia azedarach (Syringa berry) caused muscle tremors, kicking movements and respiratory distress. Lantana camara (Cherry pie) poisoning resulted in extremely inflamed eyes with copious yellow exudates extending down their beaks and onto their necks. Bentonite was administered by gavage at a dose of 5 g/kg. Poisoning in these cases is usually associated with the farmer allowing his/her birds to roam free-range in paddocks in which toxic plants are growing. Toxic plants should be removed from grass cut for hay. The author is willing to send photographs of all poisonous plants if requested by a reader.     

鸵鸟流感研究进展

自９０年代以来，驯养鸵鸟在世界很多国家发展迅猛，已成为经济动物养殖业中重要成员。然而，随之鸵鸟流感也扩散蔓延，危害严重而复杂。本文仅就流感病毒及其疫苗方面的新进展和世界鸵鸟流感现状作一论述。     

Ostrich (<Emphasis Type="Italic">Struthio camelus</Emphasis>) production in Egypt

This review discusses the historical, developmental and practices of ostrich farming in Egypt. In the early 20th century, ostrich farming was very important for production of ostrich feathers and documents were produced to perfect the art of procuring the plumes from the birds and subsequently processing them. Pharaohs used ostrich feathers for adornment. Of 43 provinces, 12 were featured in 2003-2004 as farming ostriches: Alexandria, Al-Behera, Al-Dakahlia, Al-Wadi Al-Gadid, Aswan, Cairo, El-Sharkia, Geiza, Ismailia, Kafr-El-Sheikh, Matrouh and Nubaria. Abattoirs and tanneries specialising in ostrich handling are limited to two. Egypt has numerous strengths and opportunities to develop its ostrich sector. Rising meat prices suggest that fresh ostrich meat is unaffordable to many locals. Funds may be allocated to local advertising campaigns to promote ostrich meat; provision of incentives to farmers; and improving the capacity of abattoirs.     

陕西关中地区非洲鸵鸟适应性研究

通过对引入陕西的120只非洲黑颈鸵鸟行为、生命体征、生产性能、抗病性能研究。结果发现,非洲黑颈鸵鸟引入陕西关中地区后三大生命体征平稳,抗逆性强,采食行为、性行为正常,生长发育、繁殖性能保持稳定上升状态。子二代种鸟的开产日龄无异于原非洲种鸟,且产蛋数、种蛋受精率和孵化率于开产第三年时达稳产、高产状态。子二代鸟在生长速度方面与子一代鸟比较,表现为平均日增重曲线峰值前移和达90公斤体重的饲养月龄提前一个月。非洲种鸟引入后,表现出了该物种独特的适应性、抗逆性及优秀的经济性能。     

鸵鸟骨骼观察

为适应奔跑和支持体重,鸵鸟的后肢骨骼特别发达。股骨和小腿骨,其形态结构与家畜相似。头骨断面呈海绵状,颈椎18枚,腰椎、荐椎、尾椎愈合成腰荐骨。胸骨扁而平呈板状,无龙骨突。     

鸵鸟新城疫病毒微量血凝抑制试验影响因素的研究

对鸵鸟新城疫病毒微量血凝抑制试验进行了研究,找到了影响该试验的主要因素,即被检血清中的非特异血凝抑制因子和凝集因子、稀释剂及其pH值、实验室温度、鸡红细胞的来源等。消除这些因素的影响,可明显提高这一试验的准确性。
