摘要:
为研究制备的5批新型磷霉素壳寡糖盐的抑菌性能及保存条件,采用微量肉汤稀释法,以标准磷霉素钙作为对照,测定5批新型磷霉素壳寡糖盐药品对大肠杆菌、耐甲氧西林金黄色葡萄球菌、铜绿假单胞菌、肺炎克雷伯菌、沙门氏菌等5种病原细菌的最低抑菌浓度(MIC)值;还分别测定了5批药品在-20 ℃冰箱及常温干燥条件下保存7 d不同保存条件下的抑菌活性。结果表明:新型磷霉素壳寡糖盐对耐甲氧西林金黄色葡萄球菌和铜绿假单胞菌的MIC值为3.9~15.6 μg/mL,对肺炎克雷伯菌的MIC值为15.6~52.1 μg/mL,对沙门氏菌的MIC值为104.2~125 μg/mL,对大肠杆菌的MIC值为15.6~104.2 μg/mL;本药品在-20 ℃冰箱条件下抑菌效果稳定,常温干燥条件下保存后,对铜绿假单胞菌和耐甲氧西林金黄色葡萄球菌的MIC值从3.9~15.6 μg/mL提高至125~250 μg/mL。表明新型磷霉素壳寡糖盐具有一定的抑菌作用,需在低温环境下保存。
Abstract:
To study the bacteriostatic properties and storage conditions of fosfomycin chitosan oligosaccharide salts, A micro broth dilution method was established by using standard phosphomycin calcium as a blank control. The minimum inhibitory concentrations(MICs) of new fosfomycin chitosan oligosaccharide salts against five pathogenic bacteria such as Escherichia coli(Eco), Methicillin-resistant Staphylococcus aureus(MRSA), Pseudomonas aeruginosa(Pae), Klebsiella pneumoniae(Kpn) and Salmonella(Sal) were determined. Moreover, the bacterios tatic activities of new fosfomycin chitosan oligosaccharide salts were determined under two different conditions: at -20 ℃ and 25 ℃ for 7 d. The results show that the MICs are 3.9-15.6 μg/mL for MRSA and Pae, 15.6-52.1 μg/mL for Kpn, 104.2-125 μg/mL for Sal, and 15.6-104.2 μg/mL for Eco, respectively. The bacteriostatic effect is stable under the condition of -20 ℃. After stored at 25 ℃,the MICs for MRSA and Pae increase to 125-250 μg/mL. The samples have bacteriostatic activity and should be stored at low temperatures.
