Abstract
Chlamydophila abortus is a ubiquitous organism that causes ovine enzootic abortion (OEA), a major form of infectious abortion. C. abortus infection usually remains silent until the affected animal aborts late in gestation or gives birth to a weak or dead fetus. C. abortus was incriminated as an important cause of ovarian hydrobursitis in female dromedaries which might lead to conception failure, some authors directly associated chlamydiosis with abortion and calf mortality in female camels. Chlamydial organisms may be seen in stained smears of the placenta and in vaginal swabs from freshly aborted dams. They can also be isolated from the placenta or fetal organs, products of abortion, uterine discharge, and vaginal fluids. Isolation of the organism is only possible in living cells, such as chicken embryos or tissue cultures. Chlamydial DNA can be detected using PCR or microarray methods. Several antibiotics are effective against C. abortus, the most used of which are oxytetracyclines.
