如何进行血清分型以及血清的种类

Aook 2011-08-24

什么是诊断血清?

用于检测各种生物体抗原的含有特定凝集素的液体产品

用于血清学中研究生物组织以确定其具体血清分型 (主要用于流行病学目的)

What is Antisera?

Liquid products containing specific agglutinins to various organism antigens

Used for the serological study of organisms to determine their specific serotype (primarily for epidemiological purposes)

它是如何制造的?

用特定生物体给健康兔子进行超免疫接种。收集产生的抗体,加热, 过滤 ,吸收,最后制成成品

How is it made?

Healthy rabbits are hyper-immunized with specific organisms. The antibodies are harvested , heated, absorbed and filtered  to produce the final product

诊断血清的种类

多价诊断血清包含几个不同的诊断血清抗体,并作为初次筛选使用

单价诊断血清 包含一种单一抗体并且经常在多价诊断血清缩小抗原选择范围后使用

混合诊断血清 包含所有的抗体. 例- 沙门菌属乳胶

Types of Antisera

Polyvalent antisera contain several different antibodies and are used as an initial screen

Monovalent antisera contain a single antibody and are usually used after the polyvalent sera has narrowed down the selection of antigens

Omnivalent antisera contains all of the antibodies. I.e.- Salmonella latex

如何进行血清分型?


玻片凝集法

试管凝集法

How is serotyping done?


Slide Agglutination Method

Tube Agglutination Method


 
 

玻片凝集法

用甲醛生理盐水对机体组织进行悬浮沉降

 
在一张载玻片上滴上一滴诊断血清和一滴待检菌液

 

用铂丝混合2滴液体
轻摇载玻片,1分钟后观察凝集情况

 

有明显凝集出现即为阳性

Slide Agglutination Method

Suspend colony of organism  in formol saline

   
Add One drop of antisera +one drop of bacterial suspension to a glass slide

   
Mix two drops using a platinum wire
Rock slide and observe agglutination within 1 minute

    
Strong agglutination is considered positive

试管凝集法

将培养液在37度环境下放置6-8 小时

 

用甲醛生理盐水稀释培养液

  

滴入.05ml 的诊断血清和.5ml 的稀释待检菌液到一个 12 x 75 的试管中
(2种方法始终保持在生理盐水的环境下,以监控自动凝集)

  

混合,在 52度下静置1小时.

   

检查凝集情况 (不要摇晃)

Tube Agglutination Method

Grow culture for 6-8 hours at 37 C in broth

   

Dilute culture with formol saline

    

Add .05ml of antisera and .5ml of diluted bacterial suspension to a 12 x 75 test tube
(Always run a saline control for both methods to check for auto-agglutination)

    

Mix and incubate at 52 C for 1 hr.

     

Check for agglutination (do not shake)
