The main cause of enzootic abortion in sheep is Chlamydia abortus, which often affects ewes in the later stages of pregnancy (OEA). This case study describes a rare case of C. abortus infection in a two-month-old ovine fetus from a 13-month-old primiparous sheep, which is an exceptionally early expression of the disease. Clinical examination revealed typical placental lesions, including swollen and crimson chorioallantois due to edema, inflammatory chorion, and cream-colored exudate on membrane surfaces. The diagnosis was confirmed by ELISA testing, which found specific antibodies against C. abortus in the ewe's blood samples. Because it challenges our current understanding of the dynamics of C. abortus infections, which typically induce late-term abortions in sheep, this occurrence is particularly significant. The flock's seven-month history of repeated abortions indicated an endemic infection pattern. Regardless of gestational age, this study emphasizes the importance of comprehensive diagnostic testing for aborted fetuses and the potential that C. abortus might cause pregnancy loss earlier than is often recognized. These findings contribute to our understanding of OEA and may influence future approaches to the prevention and management of diseases in sheep populations.
