Ticks infesting cattle represent a serious problem for improvement of cattle productivity in South Sudan. There has been limited information on ticks and tick-borne diseases in southern Sudan. This study was initiated to update the current distribution of ticks infesting cattle in the Central Equatoria region of South Sudan. The surveys for the present study were conducted at various cattle camps in Juba, Mangalla and Terekeka between December 2004 and June 2005. A total of 2322 ticks were collected from the bodies of 88 randomly selected cattle. Ticks were preserved in 70% ethanol for later identification. Seven ixodid tick species were found to infest cattle in Juba whilst six species were recorded in Mangalla and only four species in Terekeka. Amblyomma variegatum was the most common and widely distributed species found on cattle across all the study locations. Amblyomma lepidum was not found during this study. Based on these findings, it would be advisable to preempt the situation and institute containment procedures before possible East Coast fever outbreaks occur.
蜱虫寄生在牛身上是南苏丹提高牛生产力的一个严重问题。关于苏丹南部蜱虫和蜱传疾病的信息有限。本研究旨在更新南苏丹中赤道州寄生在牛身上的蜱虫的当前分布情况。本研究的调查于2004年12月至2005年6月期间在朱巴、曼加拉和特雷凯卡的各个牛营地进行。从88头随机挑选的牛身上共采集到2322只蜱虫。蜱虫保存在70%乙醇中以备后续鉴定。在朱巴发现有7种硬蜱寄生在牛身上，在曼加拉记录到6种，而在特雷凯卡仅发现4种。变异革蜱是在所有研究地点的牛身上发现的最常见且分布最广的物种。在本研究期间未发现鳞斑钝眼蜱。基于这些发现，在可能发生东海岸热疫情之前预先采取措施并制定控制程序是明智的。
