Coxiella burnetii is a zoonotic bacterium that can infect a wide range of animals including horses. However, its circulation dynamics in and through horses are still unclear. The aim of this study was to evaluate prevalence of C. burnetii and its genomic characteristics in horse sera samples in the North of Iran (Golestan Province). The samples were collected in 2018 and the age, sex, and breed of each animal were recorded. Nested-PCR was used to detect C. burnetii based on the presence of the transposable gene IS1111. The results showed that 7.50 % (P < 0.05; 95 % CI: 0.5 %–0.12 %) of the examined sera samples were positive for C. burnetii. Based on the resuls, prevalence of C. burnetii in the age groupof < Years 1–5 (p-value <0.05, 95 % CI: 1 %–8 %) was less than the age group of >6 years old (p-value <0.05, 95 %, CI: 7 %–19.8 %). In previous studies, it was concluded that the horses' population in Golestan Province should be considered as an important factor in the epidemiology of Q fever and consequently in public health. Further studies should be implemented to evaluate if horses may be relevant indicators of zoonotic risk in urban and suburban endemic areas.

伊朗马血清中伯氏柯克斯体的分子检测。



伯内特柯克斯体是一种人畜共患细菌,可以感染包括马在内的多种动物。然而,其在马体内和通过马的循环动态仍不清楚。本研究的目的是评估伊朗北部(古勒斯坦省)马血清样本中伯内特隐球菌的流行率及其基因组特征。样本于 2018 年采集,记录每只动物的年龄、性别和品种。基于转座基因 IS1111 的存在,使用巢式 PCR 来检测C.burnetii 。结果显示,7.50%(P < 0.05;95% CI:0.5%–0.12%)的检测血清样本呈伯氏念珠菌阳性。根据结果​​,< 1-5 岁年龄组中伯氏念珠菌的患病率(p 值 <0 id=46>6 岁(p 值 <0.05,95 %,CI:7 %–19.8 %)之前的研究得出的结论是,古勒斯坦省的马匹数量应被视为 Q 热流行病学的一个重要因素,因此应开展进一步的研究来评估马匹是否可能是人畜共患病的相关指标。城市和郊区流行地区的风险。
