绿脓杆菌国际抗原分型系统(IATS)-20型血清的试制及应用

本文根据“绿脓杆菌IATS补充三株新血清型菌株的建议”,将3株新菌株加入到IATS中,使IATS由17个血清型发展为20个血清型,并中量试制3批IATS-20血清,经检定符合新制定的“绿脓杆菌分型血清制造及检定规程”要求。为此,曾将3批分型血清赠送给国内外有关实验室进行应用考核,现收到4个国家10个实验室的应用考核结果,共计检定了1685株绿脓杆菌,其总的分型率为97.51％,所加入的3个新血清型菌株占分离菌株数的3.62％,但巴基斯坦和美国较多,分别为9.64％和7.(?)％,说明加入此3个血清型十分必要。

Trial Production and Examination of Pseudomonas Aemginosa Typing Sera According to the Supplemented International Antigens Typing Scheme

This paper reported that three batches of the sera prepared based on the supplemented IATS-20 were examined in this laboratory and 10 laboratories from other 4 countries. After the quality of the sera successfully had been passed by inspection of NICPBP of China, many sets of them were sent to the laboratories of other countries for further investigation. The results from 10 laboratories of 4 countries showed the sera were specific and sensitive in slide agglutination, and 97.51 percent of 1685 clinical isolates were typable. However, 3.62 percent of these strai ns, especially in Pakistan and U. S. A. (9.69 and 7.95 percent respectively) belonged to 3 new supplemented serotypes. Obviously it would be better if 3 new antigens could be added to IATS.
