In the study for an animal model of onchocerciasis, particularly one dependent on a Simulium vector, the prevalence of Onchocerca lienalis in Georgia cattle was assessed. In 7 collections of cervical and umbilical skin samples and nuchal ligaments made between April and December, 1975, adult parasites were found in fascia of the ligamentum nuchae of 62 of 124 animals (50.0%), and microfilariae were present in 1 or more of the skin samples from 85 to 124 cattle (68.6%). Infections occurred in cattle of all ages examined (from 2 to more than 10 years). Microfilariae were found more frequently and abundantly in umbilical than in cervical skin. They were present in 47 of 62 cattle in which adult nematodes occurred, but also present in 38 of 62 cattle in which no adult nematodes were discovered. The adult nematodes caused considerable inflammation in the fascial sheath of the ligamentum muchae.
在对盘尾丝虫病动物模型的研究中，尤其是依赖蚋作为传播媒介的模型，对佐治亚州牛体内牛盘尾丝虫的流行情况进行了评估。在1975年4月至12月期间采集的7组颈部和脐部皮肤样本以及项韧带样本中，在124只动物的62只（50.0%）的项韧带筋膜中发现了成虫寄生虫，并且在85至124头牛的1个或更多皮肤样本中发现了微丝蚴（68.6%）。在所检查的所有年龄段的牛（2岁至10岁以上）中均有感染发生。微丝蚴在脐部皮肤中比在颈部皮肤中更频繁且大量地被发现。它们存在于62只出现成虫线虫的牛中的47只，但也存在于62只未发现成虫线虫的牛中的38只。成虫线虫在项韧带的筋膜鞘中引起了相当程度的炎症。
