Comparison of antigenic structure and pathogenicity of bovine intestinal Chlamydia isolate with an agent of epizootic bovine abortion.
A bovine fecal Chlamydia, isolated from a clinically normal cow, had pathogenic capabilities and antigenic structure similar to those of a chlamydial agent of epizootic bovine abortion (EBA). Intravenous inoculation of the fecal chlamydia into a pregnant heifer caused abortion and lesions in the fetus indistinguishable from those of experimentally induced EBA. In serotests with species-specific complement fixation antigens, the intestinal agent was similar to the EBA agent.
