产品详情
Gamithromycin 是一种可以抑制 MmmSC 菌株 B237 和 Tan8 生长的抗菌剂,MIC 值分别为 0.00012 和 0.00006 μg/mL。
生物活性
Gamithromycin is an antimicrobial agent which can inhibit the growth of MmmSC strains B237 and Tan8 with MICs of 0.00012 and 0.00006 μg/mL, respectively.
性状
Solid
IC50 & Target[1][2]
MIC: 0.00012 μg/mL (MmmSC strain B237), 0.00006μg/mL (MmmSC strain Tan8)
体外研究(In Vitro)
The MIC values in serum are significantly lower than those in artificial medium; at an initial inoculum size of 10 cfu/mL, these are 64-, 8- and 64-fold lower for gamithromycin, tylosin and tilmicosin, respectively, against MmmSC strain B237 in serum compare to artificial medium. A similar pattern emerges for Tan8. Heat-inactivation of serum results in an MIC for gamithromycin that is higher than in either non-treated serum or artificial medium. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
The proportion of foals that recover without the need for a change in treatment is significantly (P<0.048) higher for foals treated with Gamithromycin (GAM) (38 of 40; 95%) or AZM-RIF (39 of 40; 98%) compare to control foals (32 of 41; 78%). The clinical scores, number of abscesses and the abscess scores after 1 and 2 weeks of treatment are significantly lower for foals treated with Gamithromycin (GAM) or AZM-RIF compare to control foals. The WBC count of foals treated with Gamithromycin (GAM) is significantly higher than that of foals treated with AZM-RIF on week 3 of treatment. has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。
