常見問題列表
泰地羅新具有特殊的三氮結(jié)構(gòu)，注射后吸收更迅速，細菌外壁穿透能力更強，與細菌核糖體蛋白結(jié)合位點更多，從而使其抑菌和殺菌的作用比一般的大環(huán)內(nèi)酯類抗生素更強。同時其特殊的三氮結(jié)構(gòu)可以延長泰地羅新在肺組織和支氣管液中有效濃度時間。
泰地羅新是廣譜抗菌藥，對一些革蘭氏陽性和革蘭氏陰性細菌均具有抗菌活性，對引起豬、牛呼吸系統(tǒng)疾病的病原菌尤其敏感，如胸膜肺炎放線桿菌、多殺性巴氏桿菌、支氣管敗血波氏桿菌、副豬嗜血桿菌以及溶血性曼海姆菌、睡眠嗜組織菌等。
Tildipirosin exhibits the inhibitory effect on C. coli species, and 23 of 31 (74%) isolates have MICs of 8 or 16 μg/mL while 8 of 31 (26%) have MIC >256 μg/mL. MICs against C. jejuni are 8-64 μg/mL. Tildipirosin against S. enterica and E. coli are 2-8 μg/mL. Tildipirosin inhibits the treponeme isolates form from CODD lesions from 19 sheep, with MIC90 of 0.0469 mg/L. The P. multocida B130 clones show the MIC of 0.25 mg/L for tildipirosin. The 10 P. multocida isolates that carry only erm(42) exhibit MIC of 16-32 mg/L for tildipirosin. The single M. haemolytica that harbours only erm(42) shows MIC of 32 mg/L for tildipirosin.
The mean percentage of lung consolidation for tildipirosin (4 mg/kg, s.c.)-treated calves is significantly lower than those for tulathromycin-treated and control calves. Metaphylactic administration of tildipirosin to calves 5 days prior to H somni challenge prevents subsequent culture of the pathogen from bronchial secretions and is more effective in minimizing clinical disease and lung lesions than is metaphylactic administration of tulathromycin.
