Abstract
Summary
Ascitic fluids were collected from mice after immunization with nonviable vaccines for Chlamydia psittaci, challenge with the respective viable agent, and implantation of Sarcoma 180. The fluids produced against the Borg, 6BC, and New Jersey strains contained useful titers of antibody demonstrable by neutralization and complement fixation titrations. Neutralization was demonstrable against intraperitoneal challenge in mice, but was slight or negligible against intracerebral challenge in mice and against inoculation into the yolk sac of embryonated eggs.
