ABSTRACT
Objective:
To investigate overall quality status of rose bengal agar culture medium for drug control in China to provide technical support for the drug standard revision.Methods:
Four quality control microorganisms, namely Aspergillus niger, Candida al-bicans, Staphylococcus aureus and Escherichia coli, were used to evaluate the quality of rose bengal agar culture medium from 7 domes-tic and foreign manufacturers.Results:
Including the control medium, the pH value of all the 8 media was different. The growth rate of Aspergillus niger and Candida albicans in the seven tested media were all above 0. 7 without significant difference (P>0. 05). The selectivity factors of Staphylococcus aureus in the seven media and the control medium was more than 6. The eight media showed differ-ences in the selectivity factors of Escherichia coli. Among them, A, B, C, E, G and the control medium had no inhibitory ( selectivi-ty) , while D and F showed certain selectivity.Conclusion:
The rose bengal agar media from different manufacturers for drug control show similar growth-promoting ability with different pH value and selectivity to Escherichia coli.
