磷酸泰乐菌素对鸡毒支原体的抑菌试验和对鸡毒支原体病的治疗试验

Bacteriostatic Effect of Tylosin Phosphate on Mycoplasma gallisepticum and Its Treatment Test for M.gallisepticum Infection

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 。

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.
