“…Prevalence in our study was higher than other similar studies in Iran. Molecular prevalence of C. burnetii in sheep abortions in Mashhad county (northeastern Iran), Sistan and Baluchestan province (southeastern Iran) and Fars province (southern Iran) were reported as 17.3%, 16.6% and 2.7%, respectively [12][13][14]. All of these studies used convenience sampling similar to our study.…”

“…However, the very small number of samples from other provinces made it difficult to compare in our study. In a study in Mashhad county, 25% of cattle fetuses were positive for C. burnetii [12]. In other countries, the prevalence of C. burnetii in cattle abortions was 4% in Turkey [17], 11.6% in Italy [18], 25.9% in Hungary [19] and 35% in Cyprus [22].…”

Background Coxiella burnetii is the causative agent of Q fever which is a highly infectious zoonotic disease. C. burnetii has become one of the most important causes of abortion in livestock, which can lead to widespread abortions in these animals. There are very limited studies on the prevalence of C. burnetii infection in cases of animal abortion in Iran. The aim of this study was to investigate the occurrence of C. burnetii in ruminant abortion samples in Iran. Methods Abortion samples from cattle, sheep and goats were collected from different parts of Iran and were tested using Real-time PCR targeting the IS1111 element of C. burnetii. Results In this study, 36 samples (24.7%) of the 146 collected samples were positive for C. burnetii. The prevalence of C. burnetii was 21.3% (20 of 94 samples) in sheep samples. Also, 10 of 46 cattle samples (21.7%) were positive. All six goat abortion samples were positive for C. burnetii. Conclusions The findings of the study demonstrate that C. burnetii plays an important role in domestic ruminant abortions in Iran, suggesting that more attention should be paid to the role of C. burnetii in domestic animal abortions by veterinary organizations. The risk of transmitting the infection to humans due to abortion of animals should also be considered.
