目的对成品硫乙醇酸盐流体培养基用于无菌检查的外观、有效性及稳定性进行评价。方法选用1批成品硫乙醇酸盐流体培养基,以3个月为1个时间节点,连续进行5次无菌检查,每次试验采用3个不同厂家的生物制品。结果使用该批培养基进行5个时间节点的无菌检查结果均合格,且外观良好。结论该成品培养基用于无菌检查具有良好的外观、有效性和稳定性,完全可取代自行配制的培养基进行无菌检查,提高工作效率及减少人为误差。
Objective To evaluate the appearance, efficacy and stability of the finished thioglycollate medium for sterility testing. Methods A batch of thioglycollate fluid medium was selected and used as a time node for three months. Five consecutive sterile tests were carried out. Three different biological products were used in each experiment. Results The results of the sterility test of the five time points were satisfactory and the appearance was good. Conclusion The finished medium is suitable for sterility test with good appearance, validity and stability. It can completely replace the self-prepared medium for sterility test, improve work efficiency and reduce human error.
