Hemoplasma species can cause infection varying from mild to severe in a wide range of hosts, including cattle and water buffalo. Two hemoplasma species, Mycoplasma wenyonii and Candidatus Mycoplasma haemobos, have been reported in cattle and water buffalo from different parts of the world to date. There was a lack of information on the presence and distribution of these pathogens in Turkey despite the negative economic impact on livestock production. This study aimed to develop a duplex PCR assay amplifying the 16S rRNA gene, in order to analyze DNA samples obtained from 297 cattle and 360 water buffaloes, and to determine the molecular prevalence of bovine hemoplasma species in Sivas province. Bovine hemoplasma species were found in 94 of 297 (31.64%) cattle and in 17 of 360 (4.72%) water buffaloes in this study. Randomly selected six positives PCR products (three samples each species) obtained from cattle and water buffaloes were sequenced, and the consensus sequences were uploaded to GenBank. Nucleotide similarity of 96.97-100% was determined between M. wenyonii isolates obtained in this study and those of M. wenyonii isolates present in the GenBank database, whereas C. Mycoplasma haemobos isolates from this study shared 99.04-100% homology with the C. Mycoplasma haemobos isolates uploaded to the GenBank. With the current study, the molecular presence of M. wenyonii and C. Mycoplasma haemobos were documented for the first time in cattle and water buffaloes in Turkey. Considering the rate of prevalence, veterinarians should take precautions against bovine hemoplasma species to protect animal health.
血支原体物种可引起广泛宿主(包括牛和水牛)的从轻度到重度的感染。迄今为止,已在来自世界不同地区的牛和水牛中报告了两种血支原体物种,即支原体和候选支原体。尽管对畜牧业生产有负面影响,但土耳其缺乏这些病原体存在和分布的信息。本研究旨在开发一种扩增 16S rRNA 基因的双重 PCR 检测方法,以分析从 297 头牛和 360 头水牛获得的 DNA 样本,并确定在锡瓦斯省牛血支原体物种的分子流行率。在本研究中,从 297 头牛中发现了 94 种(31.64%)牛血支原体物种,从 360 头水牛中发现了 17 种(4.72%)。从牛和水牛中随机选择的六个阳性 PCR 产物(每个物种各三个样本)进行测序,并将一致序列上传至 GenBank。从本研究中获得的 M. wenyonii 分离株与 GenBank 数据库中存在的 M. wenyonii 分离株的核苷酸相似性为 96.97-100%,而本研究中的 C. Mycoplasma haemobos 分离株与上传至 GenBank 的 C. Mycoplasma haemobos 分离株的同源性为 99.04-100%。通过目前的研究,首次在土耳其的牛和水牛中记录了 M. wenyonii 和 C. Mycoplasma haemobos 的分子存在。考虑到流行率,兽医应采取预防措施,防止牛血支原体物种,以保护动物健康。
