Cattle of various ages from Khartoum Province and western Sudan were surveyed for Onchocerca armillata infection by skin snip examination and some also at post-mortem examination. The former method reliably detected infection in cattle aged between nine months and eight years. Several of the older infected animals had no microfilariae in their skin. Prevalence rate and number of microfilariae per gram of skin were higher in male than in female cattle and in animals from western Sudan than those from Khartoum province. Severe pathological changes were seen in the thoracic aorta, brachiocephalic, costocervical and brachial arteries and posteriorly in the abdominal aorta to its bifurcation into the iliac arteries.
通过皮肤活检检查并对部分牛进行尸检，对来自喀土穆省和苏丹西部不同年龄的牛进行了武装盘尾丝虫感染调查。前一种方法能可靠地检测出9个月至8岁牛的感染情况。一些年龄较大的受感染动物皮肤中没有微丝蚴。每克皮肤中的微丝蚴流行率和数量在雄性牛中高于雌性牛，在来自苏丹西部的动物中高于来自喀土穆省的动物。在胸主动脉、头臂动脉、肋颈动脉和肱动脉以及腹主动脉后部直至其分叉为髂动脉处可见严重的病理变化。
