3个厂家即用型Baird-Parker琼脂平板性能评测

Performance evaluation of ready-to-use Baird-Parker agar plate of three manufacturers

目的通过对3个厂家产品的性能评测,寻找最适宜的即用型Baird-Parker琼脂平板。方法对3个厂家的Baird-Parker琼脂平板分别进行产品外观、质量控制测试、金黄色葡萄球菌菌落形态、特征性反应和菌落计数5个方面的比较,选择适合实验室的产品。结果 3个厂家的Baird-Parke琼脂平板均符合GB4789.28-2013的质控要求,但A厂家产品不稳定首先排除,B和C厂家产品的主要区别表现在外观和菌落大小方面,综合考虑实验室最终选择B厂家产品供日常检验使用。结论不同厂家的培养基产品存在差异,运输过程中保存条件的变化也会导致产品性能方面发生变化,使用前应进行严格的筛选和质量控制。

Objective To find the most suitable read-to-use Baird-Parker agar plate by evaluating the performance of three manufacturers＇ products. Methods The Baird-Parker agar plates of three manufacturers were compared to select the most suitable product for the laboratory with five different aspects, including product appearance, quality control test, Staphylococcus aureus colony morphology, characteristic reaction and colony count. Results The Baird-Parke agar plates of the three manufacturers were conformed to the quality control requirements of GB4789.28-2013. The product of manufacturer A was firstly excluded because of instability. The main differences between plate B and plate C were in appearance and colony size, and finally the product of manufacturer B was selected for daily inspection. Conclusion There are differences in the culture medium products of different manufacturers, and the changes in the storage conditions during transportation will also lead to changes in product performance, so strict screening and quality control should be carried out before use.
