Objective To screen the protective antigen of G.intestinalis and set the foundation for immune reseach of vaccine. Methods The trophozoite antigens were obtained with in vitro culture system of Giardia lamblia Stile. After further separation, purification and activity verification, the antigens were used to immunize the BALB/C mice divided into different groups,then indexes associated with immunity were determined. Through challenge infection, the most protective antigenic component of G.intestinalis were selected based on its anti-infection ability.

目的 筛选蓝氏贾第鞭毛虫的保护性抗原，免疫疫苗的研制奠定基础方法利用已建立的蓝氏贾第鞭毛虫滋养体体外培养系统，获取滋养体抗原，并进步分离、纯化、活性鉴定；然后分组免疫小鼠，检测相关免疫指标；再行攻击感染试验，视其抗感染能力，筛选出保护性强的抗原组分。

The antigenic reservoir produced a protective rate as high as 80%, which provides a way for developing new vaccine of Trypanosome evansi.

该抗原库的最佳免疫保护率达到 80%以上，它的建立为伊氏锥虫疫苗的研制开辟了一条新的途径。

Experimental mice were exposed to Trypanosome evansi after injection by different doses of antigenic reservoir. The results showed that 20 μg dose produced 83% and 67% protection to 2 sample variations after 4 immunizations. However, 3 immunizing doses could not give good protection. No protective effects were detected when experimental animals immunized by single VSG exposed to isotype from different rabbits.

用不同剂量抗原库免疫小鼠后进行攻虫，结果显示：经四次免疫后，20μg 剂量对随机抽取的两个变异体100 条虫体的保护率分别达到 83%和 67%；改变免疫方法，经三次免疫后的保护效果不理想；用单一 VSG 抗原免疫小鼠，接种来自不同兔体的同型虫体，不能起到相应保护作用。

Itproved a trypanosome can underwent antigenic variation.

采用cy鼠克隆和免疫学检测方法分离鉴定了抗原变异体ShTat1.1-ShTat1.9和ShTat2.1-ShTat2.5。

VAT ShTat1.1,ShTat1.2,ShTat1.3 and ShTat1.5were taken to study their growth characteristic,sensitivity to human serumand pathogenicity to mice.The result showed biological characteristic ofdifferent VAT were not all the same,which implied that antigenic variationof T.evansi was accompanied with variation of trypanosome otherphysiology and biochemistry property.

对伊氏锥虫安徽株单虫克隆ShTat1所产生的不同抗原变异体ShTat1.1、ShTat1.2、ShTat1.3和ShTat1.5的生长特征，对人血清敏感性以及对小鼠的致病力的比较研究发现，不同VAT的这些生物学特性不完全一致。

Objective: To investigate the antigenic components of Amaranthus spinosus pollen, and to lay theoretical base for the purification of Amaranthus spinosus pollen allergens and the standardization of allergenic vaccine.

目的：分析刺苋花粉的抗原成分以及刺苋花粉特异性变应原组分，为刺苋花粉变应原的纯化和标准化变应原疫苗的研制提供理论依据。

Monoclonal antibodies identify in dividual antigenic sites on the surface of the FMD virus.

单克隆抗体可鉴别位于FMD病毒表面的单个抗原位点。

Methods: Influenza viruses were isolated with the means of cultured in MDCK cell and embryonated eggs. The cross hemagglutination inhibition test was used for antigenic analysis and determined nucleotide sequence of HA1 genes of the influenza A (H3N3) virus.

采用MDCK细胞培养和鸡胚培养法分离流感病毒，交叉血凝抑制法进行抗原分析，对甲3型流感病毒的HA1血凝素基因作了核苷酸序列测定。
