产品描述 | Tulathromycin A (CP 472295) is a macrolide antibiotic. |
靶点活性 | Antibacterial:1 microg/ml (MIC90 for Pasteurella multocida) |
体外活性 | 145 calves were inoculated by two highly pathogenic strains of M. bovis (with minimum inhibitory concentration values for tulathromycin of 1 and >64 μg/ml). Four days after inoculation, calves with clinical BRD were treated subcutaneously with saline or tulathromycin (2.5 mg/kg). Compared with saline, BRD-related withdrawals, peak rectal temperatures, and lung lesion scores were significantly lower for tulathromycin-treated calves (P < .01). Tulathromycin was highly effective in the treatment of BRD due to M. bovis in calves regardless of the minimum inhibitory concentration of the challenge strain (1 or >64 μg/ml). The MIC90 for tulathromycin were 1 μg/ml for Pasteurella multocida (bovine), 2 μg/ml for Mannheimia (Pasteurella) haemolytica, and 2 μg/ml for Pasteurella multocida (porcine) and ranged from 4-16 μg/ml for Actinobacillus pleuropneumoniae and from 0.5-4 μg/ml for Histophilus somni (Haemophilus somnus). |
体内活性 | Each study randomly allocated 250 calves to receive tulathromycin at 2.5 mg/kg and 250 calves to receive either florfenicol at 40 mg/kg or tilmicosin at 10 mg/kg on arrival at the feedlot. Calves were housed by treatment group in pens with 50 calves/pen. The treatment groups were physiologic saline (n=160) given SC at 0.02 ml/kg, tulathromycin (n=20) given SC at 2.5 mg/kg, and tilmicosin (n = 320) given SC at 10 mg/kg. |

对于不同动物的给药剂量换算,您也可以参考 更多...
请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
