Treatment of virulent footrot with lincomycin and spectinomycin 总被引：1，自引：0，他引：1
A mixture of lincomycin and spectinomycin was investigated as a treatment for footrot in sheep. In a controlled clinical trial 92.5% of acute and chronic cases of virulent footrot were cured following a single intramuscular injection of a mixture containing 50 mg lincomycin and 100 mg spectinomycin/ml at a dose rate of 1 ml/10 kg bodyweight. No improvement in clinical response was observed in groups of sheep treated on 3 successive days with this dose rate nor in another group treated once at a dose rate 1 ml/3.3 kg bodyweight. Cure effectiveness of each of the 3 treatment groups relative to untreated controls was 89%, 95% and 95%. Efficacy of lincomycin/spectinomycin was compared with that of penicillin/streptomycin in the treatment of footrot on 2 farms in south western New South Wales. Assessments made 14 to 17 d after treatment showed that on one farm all 122 ewes treated with lincomycin/spectinomycin had recovered while 170 of 175 ewes treated with penicillin/streptomycin recovered in the same period. On the second farm 87 of 90 ewes treated with lincomycin/spectinomycin recovered, compared with 184 of 190 sheep in the same flock treated with penicillin/streptomycin. Supportive footbathing did not seem to improve the clinical response in either treatment group and the paring done was sufficient only to establish diagnosis and to remove grossly overgrown horn. 相似文献

分析了涉嫌非法添加的盐酸林可霉素注射液检测中存在的问题并提出了建议。盐酸林可霉素注射液中的非法添加物,不仅增加了动物产品药物残留的风险,还导致含量测定时色谱峰出现不同变化,使每次检测结果出现巨大差异。严厉打击此种行为需从制度和技术上加以完善。 相似文献

1. The effects of adding lincomycin to either the food (2.2 mg/kg) or drinking water (equivalent or 0.5 equivalent amount) of male broiler chicks were examined. 2. There were four treatments: control (no lincomycin), diet containing 2.2 mg lincomycin/kg, control diet plus drinking water containing lincomycin at concentrations calculated to provide an intake equivalent to treatment 2, and treatment 14 with lincomycin concentration reduced by half. 3. There was no significant effect of any treatment upon mortality, efficiency of food utilisation at 42 d of age, final body weights or monetary indices. 4. Analyses of breast, thigh and liver tissues, using a method with a sensitivity of 1.0 mg/kg, failed to reveal any evidence of lincomycin residues. 5. It is concluded that the use of lincomycin at 2.2 mg/kg may not be effective in improving either the biological or economic performance of the broiler chicken. 相似文献

Lincomycin 10 mg kg?1, IV in buffalo calves followed two-compartment open model with high distribution rate constant α (11.2?±?0.42 h?1) and K 12/K 21 ratio (4.40?±?0.10). Distribution half-life was 0.06?±?0.01 h and AUC was 41.6?±?1.73 μg mL?1 h. Large Vdarea (1.15?±?0.03 L kg?1) indicated good distribution of lincomycin in various body fluids and tissues. Peak plasma level of lincomycin (71.8?±?1.83 μg mL?1) was observed at 1 min as expected by IV route. The elimination half-life and MRT of lincomycin were short (3.30?±?0.08 and 4.32?±?0.11 h, respectively). Lincomycin 10 mg kg?1 IV at 12-h interval would be sufficient to maintain T?>?MIC above 60 % for bacteria with minimum inhibitory concentrations (MIC) values ≤1.6 μg mL?1. Favourable pharmacokinetic profile in buffalo calves and a convenient dosing interval suggest that lincomycin may be an appropriate antibacterial in buffalo species for gram-positive and anaerobic bacterial pathogens susceptible to lincomycin. 相似文献
