Abstract

Abortion is one of the most important economic issues in sheep flocks. Chlamydophila abortus is an agent of enzootic abortions in sheep. Mycoplasma agalactiae is the main etiological agent of contagious agalactia, which can cause abortion in sheep. The aim of this study was to investigate the prevalence of M. agalactiae and C. abortus among aborted ovine fetuses in Sistan and Baluchestan, Iran. Sheep owners were asked to transfer their aborted fetuses to a nearby veterinary clinic; furthermore, they were taught biosecurity principles. A total of 78 aborted sheep fetuses were collected from all over Sistan region in the autumn of 2015 and winter of 2016. The samples were then transferred in ice to the Anatomy Laboratory of the Veterinary Faculty of Zabol University, Zabol, Iran. The spleen and abomasum contents of the fetuses were sampled under sterile and safe conditions. Polymerase chain reaction was used to detect M. agalactiae and C. abortus. The results showed that 24 (30.8%) cases were infected with M. agalactiae. However, infection with C. abortus was not detected in any fetuses. There was no statistically significant relationship between such independent variables as the location of livestock, history of abortion, fetal gender and age, age and parity of ewe, and fetal infection with M. agalactiae. The high incidence of Mycoplasma contamination in this study may be due to inappropriate biosecurity measures and lack of vaccination against agalactia in sheep herds in Sistan region.
