动物疫苗用蜂胶的质量要求及工业化提取技术的研究   总被引:2,自引:0,他引:2  
本研究对动物疫苗用蜂胶质量提出了“外观,相对密度,味道,熔点”4项简易指标和“磺值,蜂蜡,可氧化性,黄酮类反应阳性,酚类化合物,杂质含量”6项理化指标,摸索出一整套有效的蜂胶工业化纯化提取工艺技术,实践证明,该工艺技术具有快速,简便,经济,实用等特点。  相似文献

20世纪70年代人们开始采用致弱的火鸡疱疹病毒(HVT)疫苗控制马立克氏病(MD),尽管这个疫苗的使用降低了疾病危害带来的损失,但鉴于MDV毒力持续增强的趋势,目前使用的疫苗可能无法很好地控制MDV的复制。RNA干扰技术的(RNAi)高度特异性和有效性使得这项技术对于开发新的抗病毒策略非常有吸引力。  相似文献

The AAHA has undertaken the development of this document in an effort to inform veterinary practitioners, clarify misunderstandings held by veterinarians, and encourage practitioners to recognize that immunization of patients is a medical procedure. As such, it is bound by the same tenets that govern the recommendation of other medical procedures-principally, that it be tailored to the needs of the individual patient. Many diseases we immunize against are ubiquitous. Many are serious and some even life threatening. Some are of limited demographic concern given the exposure risk for each patient. These factors have all been considered in developing the AAHA Canine Vaccination Guidelines. In the end, each veterinarian must do what he or she determines to be in the best interest of the patient. Vaccination of individual animals produces not only individual immunity but also population or herd immunity. Since we have no readily available and reliable way to determine if each patient has developed an adequate immune response, we encourage the practice philosophy of vaccinating more patients while vaccinating each patient no more than needed.  相似文献

用不同培养基制备的精制破伤风类毒素,加入福氏不完全佐剂免疫豚鼠,测血清中抗体效价。结果表明,加强免疫后,以酪蛋白培养基制备的精制破伤风类毒素,其免疫原性为最强,抗体的效价均值达326IU/ml,与其他各组相比差异显著,这为制备抗原用的培养基的筛选,提供了依据  相似文献

In 2005, AAHA's Canine Vaccine Task Force met to reexamine and revise guidelines on the use of vaccines in dogs. The results of the Task Force's work are summarized and tabulated in this article and are published in their entirety on the AAHA website (www.aahanet.org). The 2006 AAHA Canine Vaccine Guidelines contain information on new technological developments in vaccines, an introduction to conditionally licensed vaccines, and detailed recommendations on the use of available vaccines. Perhaps the most noteworthy addition to the guidelines is a separate set of recommendations created for shelter facilities. Vaccines are classified as core (universally recommended), noncore (optional), or not recommended. The Task Force recognizes that vaccination decisions must always be made on an individual basis, based on risk and lifestyle factors.  相似文献
