摘要: 本研究报道了普鲁卡因青霉素-硫酸双氢链霉素混悬剂对试验性感染猪链球菌病的临床药效学。以试管2倍稀释法测得兰氏C群类马链球菌对青霉素、恩诺沙星的最小抑菌浓度(MIC)分别是0.0313、0.5 mg/L。肌注给药对猪链球菌病的试验性治疗结果表明,低、中、高剂量普鲁卡因青霉素-硫酸双氢链霉素混悬剂组(0.05、0.1、0.2 mL/kg体重,每毫升混悬剂含普鲁卡因青霉素、硫酸双氢链霉素200000 IU和250000 IU)及恩诺沙星组(2.5 mg/kg体重)用药3 d,对猪链球菌病的治愈率分别是60%、80%、90%及60%,而链球菌感染对照的死亡率为70%。

Abstract: The clinical pharmacodynamics of procaine penicillin-dihydrostreptomycin sulfate suspension against Streptococcosis suum experimentally induced in swine was studied in this paper. Minimal inhibitory concentrations (MICs) of penicillin and enrofloxacin for Streptococcus equisilis were determined to be 0.0313 and 0.5 mg/L by two-fold dilution method in vitro, respectively. Following the treatment with three different dosage of procaine penicillin-dihydrostreptomycin sulfate suspension (0.05 mL/kg穊w, 0.1 mL/kg穊w and 0.2 mL/kg穊w) and enrofloxacin (2.5 mg/kg穊w) against Streptococcosis suum for 3 consecutive days, the curative rates of the infected swine were 60%, 80%,90% and 60%, respectively. The mortality of the infected but untreated group was 70%.

Key words: penicillin G procaine; dihydrostreptomycin sulfate; Streptococcosis suum; pharmacodynamics experiments
