Chlamydia abortus is a gram-negative, obligate intracellular pathogen. The causative agent causes infections by affecting the urogenital system in humans and many animals due to its zoonotic character. It has been reported that C. abortus previously developed forms characterized by abortion in sheep and goats. Studies on horses from farm animals are very rare in our country and in the world. The aim of this study was to investigate the molecular prevalence of C. abortus in mares. For our research, vaginal swab samples were collected from 123 mares from farms in different settlements in Turkey. Samples were tested by real time PCR method. As a result of the test, a total of 4 (3.25%) samples were evaluated as C. abortus positive. As a result of the evaluation, in the analysis of variance with the 95% confidence interval, it was determined as 1.0577 for Marmara, 1.0233 for Southeast Anatolia, and 1.0000 for the Eastern Anatolia region. The presence of this agent, which is very difficult in culture isolation, was demonstrated in mares by molecular diagnosis. According to this result, it was concluded that it would be beneficial to take precautions against C. abortus infections in horse farms as in other farm animals. At the same time, our study is one of the rare studies in which C. abortus infection was investigated by real time PCR in mares genital swap samples. It will also contribute to further studies to determine the presence of infection in mares to understand the transmission cycle. It should not be forgotten that this agent, which is zoonotic and causes abortions, may also carry a risk for people working in horse farms and having a history of contact.
