| 摘要 |
In view of the paucity of human material available to study the immunological events occurring after inhalation of virulent bacilli, but prior to development of clinical TB, the present invention is based in part on studies of aerosol infected rabbits. The present inventors reasoned that by 3-5 weeks post-infection, the sera from infected rabbits would contain antibodies to the antigens being expressed by the in vivo bacteria.
