【摘要】 利用磷酸泰乐菌素在试管中对鸡毒支原体进行了抑菌试验和在鸡体内对人工诱发的鸡毒支原体病进行治疗试验。结果表明 :当试管培养基中的药物浓度达到0.0016μg/ml时便能抑制鸡毒支原体的生长繁殖 ,当饲料中的药物浓度达到1g/kg 时 ,能完全阻止鸡毒支原体引起的死亡 ,明显降低气囊病变程度并增加体重 ,但对降低血清中鸡毒支原体抗体的阳性率作用不明显更多还原

【Abstract】 The Tylosin Phosphate was used to inhibit mycoplasma gallisepticum in vitro and to control mycoplasma in vivo.The test results show M.gallisepticum was sensitive to Tylosin Phosphate in medium (0.0016μg/ml).The other results show the chicken were infected with M.gallisepticum were medicated for 5 days via feed with Tylosin Phosphate or were left as unmedicated controls. The chicken were observed for 20 days.The mortality and air-sac lesions were reduced obviously when the drug in feed 1g/kg.It also could maintain weigh gain,but it couldn’t reduce seroconversion obviously in medicated birds.更多还原
