In 1973-1974, 4 controlled tests were performed in pony foals (n = 17) raised parasite-free and experimentally infected with Strongyloides westeri. Administration of infective larvae by stomach tube in 1 test resulted in low-grade infections and tended to invalidate the test. Intraoral and percutaneous (intra-aural) administration of larvae resulted in suitable test infections for 1 and 2 tests, respectively. A paste formulation of dichlorvos at 36.3 mg/kg of body weight removal from 4 ponies. Treatment of 4 the dosage rate of 44 mg/kg was consistently effective (greater than 99% to 100%) for eliminating intestinal infections of S westeri.
1973年至1974年，对17匹无寄生虫感染且经实验感染了西氏类圆线虫的小马驹进行了4次对照试验。在1次试验中通过胃管给予感染性幼虫导致轻度感染，这往往使试验无效。经口和经皮（耳内）给予幼虫分别在1次和2次试验中产生了合适的试验感染。以36.3毫克/千克体重的剂量率使用敌敌畏糊剂，可使4匹小马驹体内的寄生虫清除。以44毫克/千克的剂量率进行治疗，对于消除西氏类圆线虫的肠道感染始终有效（大于99%至100%）。
