When dexamethasone was administered intramuscularly to Hereford calves at the time of inoculation with Eimeria zurnii and E. bovis, there was no apparent effect on the resulting infection. Medication at the time of appearance of the clinical signs caused sufficient aggravation of the disease to result in the death of the animals. Administration of the drug after subsidence of the clinical signs did not cause a clinical relapse, but resulted in prolonged oocyst discharge in the feces. Treatment of uninoculated normal calves with dexamethasone caused a brief period of increased oocyst discharge without clinical signs.
在给赫里福德犊牛接种祖氏艾美耳球虫和牛艾美耳球虫时肌肉注射地塞米松,对随后发生的感染没有明显影响。在出现临床症状时用药会使病情严重恶化,导致动物死亡。临床症状消退后给药不会引起临床复发,但会导致粪便中卵囊排出时间延长。用地塞米松治疗未接种的正常犊牛会导致短时间内卵囊排出增加,但无临床症状。
