A total of 32,042 cattle, slaughtered at the Pretoria, Johannesburg and Durban abattoirs, was examined for parafilariosis and as many animals as possible were traced to the farms from which they originated. The disease is most prevalent in the Bushveld areas of the northern Transvaal. The most important factors limiting its distribution are the annual rainfall and the duration of the frost period. Mention is made of some aspects of the economic loss involved. The effect of routine anthelmintic treatment and dipping on the prevalence of the parasite is briefly discussed.
对在比勒陀利亚、约翰内斯堡和德班屠宰场宰杀的32042头牛进行了副丝虫病检查，并尽可能追踪了许多动物的来源农场。该病在德兰士瓦北部的灌木veld地区最为普遍。限制其分布的最重要因素是年降雨量和霜冻期的持续时间。文中提到了所涉及的一些经济损失方面。简要讨论了常规驱虫治疗和药浴对寄生虫流行率的影响。
