A detailed examination on a group of oxen naturally infested with Parafilaria bovicola suggested a prepatent period varying from 238 to 250 days. In these animals 54% of all lesions bled only once, 22% a second time and 24% more than twice. Of all active lesions 42% occurred in the shoulder region and decreased from this area both cranially and caudally. The same tendency was noticeable on carcasses after slaughter. During the observation period May 1974 to February 1975 the number of positive animals increased, reaching peak values during September - October 1974, after which a decline was noticed. The filaricidal effects of nine compounds were tested. These were suramin (used in combination with diethylcarbamazine citrate), thiacetarsamide sodium, fenchlorphos, phosmet, mebendazole, fenbendazole, levamisole hydrochloride and trichlorphon.
对一组自然感染牛副丝虫的牛进行的详细检查表明，潜伏期为238至250天。在这些动物中，所有病变的54%仅出血一次，22%出血第二次，24%出血两次以上。在所有活动性病变中，42%发生在肩部区域，从该区域向头侧和尾侧均减少。屠宰后的胴体上也有同样的趋势。在1974年5月至1975年2月的观察期内，阳性动物数量增加，在1974年9月至10月达到峰值，此后出现下降。测试了九种化合物的杀丝虫效果。这些化合物是苏拉明（与枸橼酸乙胺嗪联合使用）、硫乙酰胂钠、皮蝇磷、亚胺硫磷、甲苯咪唑、芬苯达唑、盐酸左旋咪唑和敌百虫。
