ABSTRACT:
The present invention relates to a polypeptide vaccine and method to immunize subjects against Chlamydia. In particular, this invention relates to essentially pure polypeptides of Chlamydia psittaci strain DD-34 ranging from about 40 to 140 kilodaltons in a pharmaceutically acceptable carrier. These compositions are used to immunize several species of animals against Chlamydia. More specifically, this invention relates to the discovery of a highly immunogenic essentially pure polypeptide of Chlamydia psittaci strain DD-34 having a molecular weight of about 96 kilodaltons.
