用途: Tulathromycin A is a macrolide antibiotic.IC50 Value: 1 microg/ml (MIC90 for Pasteurella multocida) [2]Target: Antibacterialin vitro: Two highly pathogenic strains of M. bovis (with minimum inhibitory concentration values for tulathromycin of 1 and >64 microg/ml) were inoculated into 145 calves. 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 64 microg/ml) [1]. The lowest concentrations inhibiting the growth of 90% of isolates (MIC90) for tulathromycin were 2 microg/ml for Mannheimia (Pasteurella) haemolytica, 1 microg/ml for Pasteurella multocida (bovine), and 2 microg/ml for Pasteurella multocida (porcine) and ranged from 0.5 to 4 microg/ml for Histophilus somni (Haemophilus somnus) and from 4 to 16 microg/ml for Actinobacillus pleuropneumoniae [2]. in vivo: Each study randomly allocated 250 calves to receivetulathromycin at 2.5 mg/kg and 250 calves to receive either tilmicosin at 10 mg/kg (Colorado site) or florfenicol at 40 mg/kg (Idaho and Texas sites) on arrival at the feedlot. Calves were housed by treatment group in pens with 50 calves/pen [3]. The treatment groups were physiologic saline (n = 160) given SC at 0.02 ml/kg, tulathromycin (n = 320) given SC at 2.5 mg/kg, and tilmicosin (n = 320) given SC at 10 mg/kg [4].Tulathromycin is a triamilide antimicrobial that has been approved for use in the treatment and prevention of bovine respiratory disease and the treatment of swine respiratory disease. Toxicity: No adverse events related to tulathromycin were reported [4].Clinical trial: 物理化学性质: CAS号:217500-96-4 常用中文名:托拉菌素 A 常用英文名:Tulathromycin A 分子式:C41H79N3O12 分子量:806.079 密度:1.2±0.1 g/cm3 沸点:853.8±65.0 °C at 760 mmHg 熔点:N/A 闪点:470.2±34.3 °C 储存条件:-20℃ |
