Abstract

The passive transfer of rabbit anti-mycobacterial immunoglobulins was directed against either living or soluble extracts of Mycobacterium tuberculosis strain H37Rv, which promotes the multiplication of the BCG strain of M. tuberculosis in the spleen of mice infected with low doses of this latter strain. This enhancing effect was reduced significantly when antisera were absorbed with living BCG. Moreover, such treatment led to the removal of all hemagglutinating antibodies when antisera were tested against either BCG or H37Rv soluble extracts. Therefore, it is most probable that the enhancing effect is related to the presence of mycobacterial antibodies.

摘要

兔抗分枝杆菌免疫球蛋白的被动转移针对的是结核分枝杆菌H37Rv菌株的活菌体或可溶性提取物,这会促进结核分枝杆菌卡介苗菌株在感染低剂量该后一种菌株的小鼠脾脏中的增殖。当抗血清用活卡介苗吸收时,这种增强作用会显著降低。此外,当抗血清针对卡介苗或H37Rv可溶性提取物进行检测时,这种处理会导致所有血凝抗体被去除。因此,增强作用很可能与分枝杆菌抗体的存在有关。
