A sudden decrease in milk yield, increased respiratory rate and occasional coughing were observed in dairy cows on two farms in spring 1991. Pigs were also kept on these farms, and pastures grazed by the cattle had been fertilised with pig slurry. Laboratory investigations of some of the cattle showed eosinophilia and high ELISA titres of antibodies against Ascaris suum. On one farm the clinical symptoms disappeared after the animals had been treated with oxfendazole and on the other farm the symptoms disappeared spontaneously with time.
1991年春季，在两个农场的奶牛中观察到产奶量突然下降、呼吸频率增加和偶尔咳嗽。这些农场也养猪，牛群放牧的牧场用猪粪施肥。对一些牛的实验室检查显示嗜酸性粒细胞增多，以及针对猪蛔虫的抗体ELISA滴度很高。在一个农场，动物用奥芬达唑治疗后临床症状消失，而在另一个农场，症状随时间自行消失。
