Ticks and tick-borne diseases are major impediments to livestock production. To date, there have been several studies on the prevalence of tick-borne pathogens (TBPs) in cattle, but very few studies have documented TBPs in goats in Uganda. In this study, polymerase chain reaction assays and sequence analysis of different molecular markers were used to assess the presence and genetic characteristics of TBPs in 201 goats from Kasese district in western Uganda. The risk factors associated with TBP infections were also analyzed. We detected spp. (13.4%), (10.9%), (5.5%), (5.5%), and (0.5%). The sequences of ssu rRNA and genes showed some degree of diversity among the parasite isolates in this study. The sequence formed a well-supported clade with isolates from ticks from Uganda. Wildlife interaction, sampling location, low body condition score, tick infestation, and herd size were significantly associated with TBP infections in the goats. The findings in this study provide important information on the epidemiology of tick-borne pathogens in Uganda, and show that goats could be potential reservoirs for tick-borne pathogens.
蜱虫和蜱传疾病是畜牧业生产的主要障碍。迄今为止,已有多项关于牛蜱传病原体(TBPs)流行情况的研究,但在乌干达,记录山羊体内TBPs的研究却非常少。在本研究中,采用聚合酶链反应分析和不同分子标记的序列分析,评估了乌干达西部卡塞塞区201只山羊体内TBPs的存在情况及其遗传特征。还分析了与TBP感染相关的风险因素。我们检测到了[具体物种1](13.4%)、[具体物种2](10.9%)、[具体物种3](5.5%)、[具体物种4](5.5%)和[具体物种5](0.5%)。本研究中,[具体物种1]的小亚基核糖体RNA(ssu rRNA)和[具体基因]序列在寄生虫分离株中表现出一定程度的多样性。[具体物种1]的序列与来自乌干达[具体蜱虫种类]蜱虫的分离株形成了一个得到充分支持的进化枝。野生动物接触、采样地点、低体况评分、蜱虫感染和畜群规模与山羊的TBP感染显著相关。本研究结果为乌干达蜱传病原体的流行病学提供了重要信息,并表明山羊可能是蜱传病原体的潜在宿主。
